New Results From Landmark NURTURE Study Show That Pre-Symptomatic SMA Patients Treated With SPINRAZA (nusinersen) Continue to Demonstrate Sustained…

By daniellenierenberg

DetailsCategory: DNA RNA and CellsPublished on Wednesday, 10 June 2020 16:58Hits: 131

CAMBRIDGE, MA, USA I June 10, 2020 I Biogen Inc.(Nasdaq: BIIB) today announced new results from NURTURE, the longest study of pre-symptomatic patients with spinal muscular atrophy (SMA) that is transforming expectations of early treatment with SPINRAZA (nusinersen). In infants genetically diagnosed with SMA, new data demonstrate that early and sustained treatment with SPINRAZA for up to 4.8 years enabled unprecedented survival. Patients continued to maintain and make progressive gains in motor function compared to the natural course of the disease. These results are being presented at the virtual Cure SMA Research & Clinical Care Meeting taking place June 10-12, 2020.

The new data include nearly a year of additional follow-up for NURTURE study participants. As of February 2020, all patients treated (n=25; median age of 3.8 years old) were alive and remained free of permanent ventilation. In the absence of treatment, the majority of children with SMA Type 1 would, on average, not reach their second birthday. Additionally, all children who achieved the motor milestone of being able to walk independently (many within a normal timeframe) have maintained that ability from the first occurrence until the last visit.

The impact of early and sustained SPINRAZA treatment on these infants and their families is remarkable. Ive had the privilege to watch them grow into active young children, many of whom have experienced progress in motor function consistent with children their age who do not have SMA, said Kathryn Swoboda, M.D., the Katherine B. Sims, M.D., Endowed Chair in Neurogenetics and Director of the Neurogenetics Program, Massachusetts General Hospital. The new results from NURTURE continue to bolster the substantial benefit of both prompt diagnosis and early and longer-term treatment with SPINRAZA.

NURTURE is an ongoing, Phase 2, open-label study of 25 pre-symptomatic patients with the genetic diagnosis of SMA (most likely to develop SMA Type 1 or 2) who received their first dose of SPINRAZA before 6 weeks old. The study has been extended by an additional three years, enabling Biogen to evaluate the longer-term efficacy and safety of SPINRAZA through 8 years of age and further understand the impact of early treatment. More information on the NURTURE study (NCT02386553) is available onclinicaltrials.gov.

Additional results from the updated interim analysis as of February 2020 show:

About SPINRAZA (nusinersen)2-4 SPINRAZA is the first therapy approved to treat infants, children and adults with spinal muscular atrophy (SMA) and is approved in more than 50 countries. As of March 31, 2020, more than 10,000 individuals have been treated with SPINRAZA. It is the only SMA treatment to combine unsurpassed real-world experience with a robust level of clinical evidence across a broad spectrum of patient populations.

SMA is a rare, genetic, neuromuscular disease that is characterized by a loss of motor neurons in the spinal cord and lower brain stem that can result in severe, progressive muscle atrophy and weakness. Approximately one in 10,000 live births have a diagnosis of SMA, and people of all ages are impacted by the disease. It is a leading genetic cause of infant mortality.

SPINRAZA, a foundation of care in SMA, is an antisense oligonucleotide (ASO), developed using Ionis Pharmaceuticals proprietary technology that is designed to target a root cause of SMA by increasing the amount of full-length survival motor neuron (SMN) protein, which is critical to maintaining motor neurons. It is administered by intrathecal injection into the fluid surrounding the spinal cord where motor neurons reside to deliver the treatment where the disease starts.

SPINRAZA currently maintains a robust clinical data set in SMA based on data from approximately 300 patients across a broad range of SMA populations demonstrating a favorable benefit:risk profile. SPINRAZA was evaluated in two randomized, double-blind, sham-controlled studies of infantile and later-onset SMA (ENDEAR and CHERISH, respectively) and supported by open-label studies that include pre-symptomatic infants (NURTURE), individuals with later-onset SMA (CS2/CS12) and an extension study of individuals who previously participated in the clinical development program (SHINE). The most common adverse events observed were respiratory infection, fever, constipation, headache, vomiting and back pain. Hypersensitivity, meningitis and hydrocephalus have been observed in the post-marketing setting. Renal toxicity and coagulation abnormalities, including acute severe low platelet counts, have been observed after administration of some ASOs. Laboratory tests can monitor for these signs.

Biogen licensed the global rights to develop, manufacture and commercialize SPINRAZA from Ionis Pharmaceuticals, Inc. (Nasdaq: IONS), a leader in antisense therapeutics. Biogen and Ionis conducted an innovative clinical development program that moved SPINRAZA from its first dose in humans in 2011 to its first regulatory approval in five years.

Molecular alterations in the extracellular matrix in the brains of newborns with congenital Zika syndrome – Science

By daniellenierenberg

How Zika affects the extracellular matrix

In some cases, Zika virus (ZIKV) infection during pregnancy leads to a series of severe defects in the fetus collectively known as congenital Zika syndrome (CZS). These include microcephaly, defective neuronal migration, and impaired cortical development. Aguiar et al. combined genomic, transcriptomic, and proteomic analyses of blood and postmortem brains and demonstrated that ZIKV-infected neonates showed a reduction in collagen expression and an increase in adhesion factor expression, alterations in the extracellular matrix consistent with the brain defects seen in CZS. Together, these datasets form a useful resource for those investigating the molecular mechanisms underlying CZS in humans.

Zika virus (ZIKV) infection during pregnancy can cause a set of severe abnormalities in the fetus known as congenital Zika syndrome (CZS). Experiments with animal models and in vitro systems have substantially contributed to our understanding of the pathophysiology of ZIKV infection. Here, to investigate the molecular basis of CZS in humans, we used a systems biology approach to integrate transcriptomic, proteomic, and genomic data from the postmortem brains of neonates with CZS. We observed that collagens were greatly reduced in expression in CZS brains at both the RNA and protein levels and that neonates with CZS had several single-nucleotide polymorphisms in collagen-encoding genes that are associated with osteogenesis imperfecta and arthrogryposis. These findings were validated by immunohistochemistry and comparative analysis of collagen abundance in ZIKV-infected and uninfected samples. In addition, we showed a ZIKV-dependent increase in the expression of cell adhesion factors that are essential for neurite outgrowth and axon guidance, findings that are consistent with the neuronal migration defects observed in CZS. Together, these findings provide insights into the underlying molecular alterations in the ZIKV-infected brain and reveal host genes associated with CZS susceptibility.

OpGen is providing its Acuitas AMR Gene Panel for rapid detection of multidrug-resistant bacterial pathogens along with its Acuitas Lighthouse Software for high resolution pathogen tracking. The second year contract includes a quarterly retainer-based project fee as well as volume-dependent per test fees for a total contract value of up to $450,000 to OpGen.

We are excited and grateful that despite the continued threat of the COVID-19 pandemic which has hit New York State harder than any other place in the world, the Department of Health of New York State and the Wadsworth Center continue to work with us and have expanded their partnership for a second year, adding up to 3,500 AMR Gene Panel tests to be run, commented Oliver Schacht, CEO of OpGen. The quick spread of antimicrobial resistant superbugs across our healthcare systems is lurking below the current medical crisis. We anticipate that with our innovative diagnostic solutions we will be able to proactively identify such pathogens leading to early intervention and lifesaving treatment. A further project expansion of this nature may include the exploration of ways to achieve SARS-CoV-2 tracking.

Paul Edwards, Chief Strategy Officer at IDC commented, Our collaboration with OpGen allows us to not only identify bacteria and antimicrobial resistance down to the gene level but also to identify new or significant results versus phenotypic results alone. This molecular epidemiology capability in turn is critical in order to rapidly identify new clusters and outbreaks which otherwise would be missed and could potentially lead to outbreaks of hospital superbugs.

The precision medicine solutions provided by OpGen to accomplish the project goals are:

Wadsworth Center Director Dr. Jill Taylor said,"Under Governor Cuomo's leadership, New York State continues to lead the nation in addressing the threat of antimicrobial resistance. Working with our private-sector partners, the Wadsworth Center is able to further advance our mission to improve the public health of all New Yorkers.

About Antimicrobial-resistant InfectionsThe Centers for Disease Control and Prevention estimates that annually in the United States we face 2.8 million infections with 35,000 deaths and $49 billion in lost productivity all attributable to antibiotic resistant infections. Among the infectious diseases the parties are working to address are carbapenem-resistant Enterobacteriaceae (CRE) bacteria; they are untreatable and hard-to-treat infections on the rise among patients in medical facilities. CREs have become resistant to all or nearly all the antibiotics we have today. Almost half of hospital patients who get bloodstream infections from CRE bacteria die from the infection. The CDC has classified CREs as one of three urgent threats to the public health.

About Wadsworth Center LaboratoriesThe Wadsworth Center laboratories stand at the forefront of biomedical and environmental sciences and their interplay.

Stem cell therapy and spinal cord injury (SCI) | Future …

By daniellenierenberg

In the UK 50,000 people have a spinal cord injury (SCI)[1]

Every year there are 2,500 new cases of SCI in the UK[1]

20-30% of people with SCI show clinically significant signs of depression[2]

People with spinal cord injury are two to five times more likely to die prematurely[2]

50kpeople in the UKhave spinal cord injury

A traumatic injury to the spine can cause a bruise, partial or complete tear in the spinal cord, leading to partial or total loss of feeling/movement in various body parts. The most common sites of injury are the cervical and thoracic areas.

Generally, spinal cord injuries (SCI) affect areas lower than the point of damage, so the higher the damage, the more movement and sensation will be lost. Spinal cord injury can even result in paraplegia and tetraplegia[3], although severity and recovery rate varies widely depending on the location and extent of the injury.

To aid recovery and lessen the risk of developing associated conditions, its essential that each patient receives appropriate rehabilitation and health maintenance support.

Stem cell therapy is rapidly evolving and offering treatment for spinal-cord injuries (SCI). Although there is no current treatment available to restore injury-induced loss of function, evidence is building that stem cell infusions into the spine may support spinal cord repair.

Positive results have been observed in phase I/II clinical trials at Puerta de Hierro Hospital in Madrid[4]. 12 patients were given doses of the new drug NC1 made from autologous mesenchymal stromal cells (MSCs) and autologous plasma. All 12 patients experienced improvements in sensitivity and 50% showed greater motor activity, decreased spasms and improved sexual function.

Since this clinical trial took place, the NC1 drug has been approved by the Spanish Agency of Medicines. However, there is still more research to be done for stem cell therapy to be widely administered for repairing spinal cord injury.

Spinal Cord Stem Cell Treatments London | Regenerative …

By daniellenierenberg

The spinal cord is a long, fragile, tube-like nervous structure that connects the brain with peripheral nerves. Damage to the spinal cord, by trauma or other means, consequently results in severe motor- and sensory deficits that usually lead to the inability to move and feel. Accidents are the most common cause of Spinal Cord Injury with catastrophic consequences for the life of the patient and their relatives. While conservative therapies aim to stabilize the patient, functional recovery in most cases is minimal.

Both preclinical and clinical studies have shown improved recovery of spinal cord injury patients when the therapy was combined with a suitable stem cell therapy. Our clinic provides access to the most advanced clinically available combination of stem cell therapies.

Spinal trauma can disrupt ascending and descending axonal pathways that lead to: inflammation, demyelination and loss of neural cells (neurons). Depending on the site of injury, functional disorders induced by cellular damage usually result in the inability to move, sensory loss and/or lack of autonomous nervous system control.

Fully regenerative therapies for spinal trauma do not exist yet. However, very promising results have been obtained with stem cell transplantation in patients with spinal trauma. The use ofMesenchymal Stem Cells (MSCs) in Spinal Cord Injury has been extensively reviewed. Experiments with MSCs have shown that their abilities to stimulate repair processes in spinal cord injury are due to the paracrine secretion of the stem cells. After 21 days of observations, even though the MSCs had not been incorporated into the regenerated host tissue, there was a significant improvement in functional recovery, from as early as one week after the treatment with MSCs.

Neuroprosthetics Market Scope and Opportunities Analysis Through 2021 – 3rd Watch News

By daniellenierenberg

Central nervous system comprises brain and spinal cord, and is responsible for integration of sensory information. Brain is the largest and one of the most complex organs in the human body. It is made up of 100 billion nerves that communicate with 100 trillion synapses. It is responsible for the thought and movement produced by the body. Spinal cord is connected to a section of brain known as brain stem and runs through the spinal canal. The brain processes and interprets sensory information sent from the spinal cord. Brain and spinal cord serve as the primary processing centers for the entire nervous system, and control the working of the body. Neuroprosthetics improves or replaces the function of the central nervous system.

Neuroprosthetics, also known as neural prosthetics, are devices implanted in the body that stimulate the function of an organ or organ system that has failed due to disease or injury. It is a brain-computer interface device used to detect and translate neural activity into command sequences for prostheses. Its primary aim is to restore functionality in patients suffering from loss of motor control such as spinal cord injury, multiple sclerosis, amyotrophic lateral sclerosis, and stroke. The major types of neuroprosthetics include sensory implants, motor prosthetics, and cognitive prosthetics. Motor prosthetics support the autonomous system and assist in the regulation or stimulation of affected motor functions.

Similarly, cognitive prosthetics restore the function of brain tissue loss in conditions such as paralysis, Parkinsons disease, traumatic brain injury, and speech deficit. Sensory implants pass information into the bodys sensory areas such as sight or hearing, and it is further classified as auditory (cochlear implant), visual, and spinal cord stimulator. Some key functions of neuroprosthetics include providing hearing, seeing, feeling abilities, pain relief, and restoring damaged brain cells. Cochlear implant is among the most popular neuroprosthetics. In addition, auditory brain stem implant is also a neuroprosthetic meant to improve hearing damage.

Request PMR insights on measuring the impact of COVID-19 coronavirus across industries.

North America dominates the global market for neuroprosthetics due to the rising incidence of neurological diseases and growth in geriatric population in the region. Asia is expected to display a high growth rate in the next five years in the global neuroprosthetics market, with China and India being the fastest growing markets in the Asia-Pacific region. Among the key driving forces for the neuroprosthetics market in developing countries are the large pool of patients, increasing awareness about the disease, improving healthcare infrastructure, and rising government funding in the region.

Increasing prevalence of neurological diseases such as traumatic brain injury, stroke and Parkinsons disease, rise in geriatric population, increase in healthcare expenditure, growing awareness about healthcare, rapid progression of technology, and increasing number of initiatives by various governments and government associations are some key factors driving growth of the global neuroprosthetics market. However, factors such as high cost of devices, reimbursement issues, and adverse effects pose a major restraint to the growth of the global neuroprosthetics market.

Innovative self-charging neural implants that eliminate the need for high risk and costly surgery to replace the discharge battery and controlling machinery with thoughts would help to develop opportunities for the growth of the global neuroprosthetics market.

A caveolin binding motif in Na/K-ATPase is required for stem cell differentiation and organogenesis in mammals and C. elegans – Science Advances

By daniellenierenberg

INTRODUCTION

Embryonic development is characterized by the temporal and spatial regulation of cell proliferation, migration, differentiation, and tissue formation. Although these processes are genetically determined, several signaling mechanisms including Wnt have been recognized as essential in regulating cell lineage specification and organogenesis (13).

The Na/Kadenosine triphosphatase (ATPase) (NKA), discovered in crab nerve fibers by Skou (4), belongs to the P-type ATPase superfamily. It has an enzymatic function that couples adenosine 5-triphosphate (ATP) hydrolysis to the transmembrane movement of Na+ and K+ in a cell lineagedependent manner. For example, while the NKA is involved in the formation of action potentials in excitable cells, its polarized distribution is key to the functionality of the epithelium.

In addition to its canonical enzymatic function, we and others have shown that the NKA has an enzymatic activityindependent signaling function through its interactions with membrane cholesterol and proteins such as Src, epidermal growth factor (EGF) receptor, and caveolin-1 (58). We use the term signaling with liberty here, referring to the ability of NKA to work as a receptor, a scaffold, and a signal integrator by regulating the functions of its interacting proteins. This newly appreciated signaling function of the NKA has been implicated in several cellular processes (912). However, direct genetic evidence supporting a role for NKA signaling in animal physiology and disease progression is still lacking. This is due, in part, to the technical difficulties in studying its signaling separately from its ATPase-mediated pumping function because the latter is required for the survival of animal cells (13). Fundamentally, it is unknown whether the signaling function is an intrinsic property of the protein NKA, as its Na+- and K+-driven enzymatic activity has been recognized as. Therefore, we were prompted to address two important questions: (i) Were the signaling and Na+/K+ transport functions of the NKA coevolved? (ii) If so, does the signaling function of NKA represent a primordial yet common mechanism for the regulation of a fundamental process in animal biology?

Structurally, the NKA is composed of both and subunits. The subunit contains the binding sites for Na+/K+ as well as ouabain, which are distinct from that of other P-type ATPases (14). It also has an N-terminal caveolin binding motif (CBM) proximal to the first transmembrane helix (fig. S1A). To assess the functionality of this motif, we made F97A and F100A mutations that map to the rat 1 NKA sequence. This strategy has been used by others to study the function of CBM in proteins other than the NKA (15). We used a knockdown and rescue protocol to generate a stable cell line (LW-mCBM) that essentially expresses just the CBM mutant 1, which was confirmed using [3H]ouabain binding assays (fig. S1B). Western blot and confocal imaging analyses showed that the expression of mutant 1 NKA in LW-mCBM was comparable to that in the control cell line, named AAC-19 cells (fig. S1, B and C). The expression of CBM mutant 1 was sufficient to restore the expression of the 1 subunit of the NKA, allowing normal plasma membrane targeting of the CBM mutant NKA in LW-mCBM cells (fig. S1, C and D). The successful generation of a stable CBM mutant 1 cell line suggests that the CBM is not essential for the enzymatic activity of the NKA because the ion-transporting function is necessary for animal cell survival (13). In further support, we conducted kinetic studies of the CBM mutant NKA. As shown in Fig. 1A, the overall enzymatic activity per unit of 1 NKA expression was identical between the control AAC-19 and LW-mCBM cells. The Km values of Na+, K+, and ouabain were comparable between the CBM mutant NKA and control (Fig. 1, B to D) (16). Together, these data indicate that the N-terminal CBM is not directly involved in the regulation of the enzymatic properties of the NKA.

(A) Crude membrane preparations were made from AAC-19 and LW-mCBM cells and measured for ouabain-sensitive ATPase activity as described in Material and Methods. (B) Ouabain concentration curve. Crude membrane from LW-mCBM cells was prepared and measured for ATPase activity in the presence of different concentrations of ouabain. Data are shown as percentage of control, and each point represents three independent experiments. Curve fit analysis and IC50 (median inhibitory concentration) were calculated by GraphPad. (C and D) Measurements of Na+ and K+ Km. Assays were done as in (B). The combined data were collected from at least three repeats, and Km value (means SEM) was calculated using GraphPad.

On the basis of the above, we next turned our attention to determining the effects of the CBM mutation on signaling capabilities of the 1 NKA. Specifically, we first conducted immunoprecipitation experiments. As we reported previously in many types of cells (8), immunoprecipitation of caveolin-1 coprecipitated 1 in AAC-19 cells. In contrast, mutation of the CBM resulted in an over 80% decrease in coprecipitated 1 in LW-mCBM cells (Fig. 2A).

(A) Cell lysates from AAC-19 and LW-mCBM were immunoprecipitated (IP) with polyclonal anticaveolin-1 antibody. Immunoprecipitated complex was analyzed by Western blot for 1 and caveolin-1 (n = 4). **P < 0.01 compared to AAC-19.

To substantiate these observations, we next conducted a detergent-free and carbonate-based density gradient fractionation procedure and found that 1 NKA and its main signaling partners (Src and caveolin-1) were co-enriched in the low-density caveolar fractions, as previously reported in epithelial cells (8, 17). In sharp contrast, the expression of the CBM mutant 1 caused the redistribution of these proteins from low-density to high-density fractions (Fig. 2B). Quantitatively, when the ratios of fraction 4/5 of each protein versus total were calculated, we found that the low-density fraction 4/5 prepared from the control AAC-19 cells contained ~60, ~70, and 80% of caveolin-1, Src, and 1 NKA, respectively. However, in LW-mCBM cells, only ~20% of caveolin-1, Src, and 1 NKA were detected in fraction 4/5 (Fig. 2B).

To address the functional consequences of the dissociation of the 1 NKA from its signaling partners in LW-mCBM cells, we exposed these cells to ouabain, a specific agonist of the receptor NKA/Src complex. As shown in Fig. 2C, while ouabain stimulated phosphorylation of extracellular signalregulated kinase (ERK), a downstream effector of the NKA/Src signaling pathway in AAC-19 cells (5, 8), it failed to do so in LW-mCBM cells.

We have previously shown that 1 NKA signaling is key to the dynamic regulation of cell growth (16, 18). As shown in Fig. 2D, LW-mCBM cells grew much slower than AAC-19 cells. 5-Bromo-2-deoxyuridine (BrdU) incorporation assays further verified that the expression of CBM mutant 1 resulted in an inhibition of cellular proliferation (Fig. 2E). In short, the above in vitro experiments indicate that the gain of CBM enables the NKA to perform the enzymatic activityindependent signaling functions.

With the preceding in vitro data suggesting that the CBM is critically important to the signaling function of the NKA, we next set forth to test the physiological significance of this finding. Thus, we generated a knock-in mouse line expressing the aforementioned CBM mutant 1. The CBM mutant (mCBM) mouse was generated using the Cre/LoxP gene targeting strategy (19), as depicted in fig. S2A. The chimeric offspring were crossed to C57BL6 females to yield mCBM heterozygous mice, and the desired F97A and F100A substitutions were verified (fig. S2B). mCBM heterozygous mice were born fertile and survived to adulthood. Our attempts to generate mCBM homozygous mice yielded no viable homozygous pups (Fig. 3A) in nearly 400 young mice genotyped by polymerase chain reaction (PCR). These results document for the first time that the CBM in the 1 subunit of the NKA represents a fundamental signaling mechanism essential for mouse embryonic development and survival.

There is evidence that endogenous ouabain is important in animal physiology because of its role in stimulating the signaling function of the NKA (10, 19, 20). Because the loss of the CBM abolishes ouabain-induced signal transduction in vitro, we tested whether administration of pNaKtide, a specific inhibitor of the receptor NKA/Src complex (21), would cause the same embryonic lethality as we observed in mCBM mice. As depicted in fig. S3, we observed no change in fetal survival after administration of pNaKtide to female mice before mating and continued until the end of pregnancy. It is important to mention that pNaKtide has been proven to be specific and effective in blocking the NKA/Src receptor signaling in vivo (2226), and our control experiments showed that pNaKtide could cross the placental barrier. Moreover, this lack of pNaKtide effect on mouse embryogenesis appears to be consistent with a previous report demonstrating that neutralization of endogenous ouabain by injection of an anti-ouabain antibody did affect the kidney development of neonatal mice but did not affect their overall survival (20). On the basis of these, we concluded that the NKA/Src receptor function in the CBM mutant embryo was not the direct cause of lethality and set out to identify a hitherto unrecognized NKA CBM-dependent yet NKA-Srcindependent underlying mechanism.

Embryo implantation within mice occurs around embryonic day 4.5 (E4.5) (27), followed by gastrulation around E5.5 to E7.5 (28), when the simple embryo develops into an organized and patterned structure with three germ layers (29). Subsequently, organogenesis takes place at E8.0 and onward; the patterned embryo starts to develop its organ systems including the brain, heart, limbs, and spinal cord.

To further analyze and explore the molecular mechanisms of the CBM mutation in the embryonic development of mice, we harvested the fertilized eggs at E1.5, and cultured them in vitro. It has previously been demonstrated that 1 knockout results in the failure of blastocyst formation (13). In contrast, we found that eggs from mCBM heterozygous parents developed into morphologically normal blastocysts. These findings indicate that loss of the CBM does not affect the molecular mechanisms necessary for blastocyst formation. Thus, a loss of functional 1 CBM and complete knockout of 1 NKA both result in embryonic lethality but differ by their specific mechanisms. Knockout of 1 NKA inevitably causes the loss of NKA enzymatic function, which is incompatible with life (13), and results in the failure of blastocyst formation in mice. In contrast, our in vitro data indicate that a loss of the CBM does not cause any notable alteration in NKA enzymatic activity, which is supported by the observation that mCBM mice are still capable of producing morphologically normal blastocysts. Consequently, CBM role in development appears to be critical at a developmental stage beyond blastocyst stage, and we further set out to identify this stage.

To this end, we collected and genotyped embryos or yolk sacs from mCBM heterozygous mice at different days of gestation. We first dissected 31 embryos at E12.5 from three different mice (Fig. 3A). Reabsorption and empty deciduae were observed in six implantation sites with only the mothers genotype detectable. At E9.5, we were able to dissect a total of 303 embryos. Sixty-four of them were mCBM homozygous (21%), 71 were wild-type (23%), and 168 were mCBM heterozygous (55%) (Fig. 3A).

To further analyze the embryonic developmental defects, we examined mCBM embryos at E7.5, E8.5, and E9.5. The embryos looked similar between wild-type and mCBM homozygous mice at E7.5 and E8.5 under dissection microscopy. However, we found several severe morphological defects in homozygous embryos at E9.5 (Fig. 3, C and D). First, the overall size of embryos was considerably reduced in mCBM homozygous embryos (about 35% the size of the wild-type embryos). In addition, the observed effect of the CBM mutant on embryonic size was gene dose dependent, as the mCBM heterozygous embryos were significantly smaller than those of wild-type embryos but much bigger than the homozygous embryos. Second, most homozygous embryos did not turn, a process normally initiated at E8.5, suggesting that the loss of a functional CBM was responsible for a developmental arrest at an early stage of organogenesis. Last, the most severe morphological defects were observed in the heads of the mCBM homozygous embryos. In addition to the reduced size (about 25% of the size of wild-type embryos), we observed that mCBM homozygous embryos failed to close their cephalic neural folds (anterior neuropore) as indicated by the arrow in Fig. 3B. This phenotype more closely resembled wild-type embryos at E8.0 to E8.5, suggesting again that the loss of CBM arrested organogenesis in its early stages. On the other hand, all heterozygous embryos, although smaller than wild-type embryos, showed normal head morphology (Fig. 3B).

To follow up on the above observations, we collected and made histological sections of wild-type, heterozygous, and homozygous embryos at E9.5 (Fig. 3, C and D). Normally, formation and closure of the anterior neuropore occurs at E9.5 (Fig. 3D). In sharp contrast, mCBM homozygous embryos developed defects in neural closure. Specifically, failure of neural tube closure at the level of forebrain, midbrain, and hindbrain was prominent in homozygous embryos (Fig. 3D).

To further explore the molecular mechanism by which the loss of the CBM led to defects in organogenesis, we next conducted RNA sequencing analyses (RNAseq) in wild-type and mCBM homozygous embryos. More than 17,000 genes were read out in either mCBM homozygous or wild-type samples. Data analyses indicated that 214 and 208 genes from mCBM homozygous embryos were significantly down- and up-regulated, respectively (fig. S4). Among them, the expression of a cluster of transcriptional factors important for neurogenesis was significantly reduced. As depicted in Fig. 4A, the expression of neurogenin 1 and 2 (Ngn1/2), two basic helix-loop-helix (bHLH) transcriptional factors (30), was significantly down-regulated in homozygous embryos. Ngn1/2 are considered to be determination factors for neurogenesis, while members of the NeuroD family of bHLH work downstream to promote neuronal differentiation (31). We found that the expression of NeuroD1/4 was further reduced in mCBM homozygous embryos. As expected from these findings, the marker of neural stem cells nestin (Nes) and other genes related to neurogenesis including huntington-associated protein 1 (Hap1), nuclear receptor subfamily 2 group E members 1 (Nr2e1), and adhesion G protein (heterotrimeric guanine nucleotidebinding protein)coupled receptor (Adgrb1) were all down-regulated in mCBM homozygous embryos (Fig. 4A). To verify these data, we performed reverse transcription quantitative PCR (RT-qPCR) analyses of both wild-type and mCBM homozygous embryos collected at E9.5. As depicted in Fig. 4 (B to D), the aforementioned transcriptional factors were all down-regulated in a cascade fashion. While a modest reduction was found with Ngn1/2, the expression of NeuroD1/4 was almost completely inhibited. To test whether the effects of the CBM mutation on the expression levels of these transcriptional factors were gene dose dependent, we also examined mRNA levels of Ngn1/2 and NeuroD1/4 in mCBM heterozygous embryos. As depicted in Fig. 4 (B and C), the expression of these genes followed the pattern found in homozygous embryos. The expression level in heterozygous embryos was significantly reduced compared to wild-type embryos but was much higher than that of mCBM homozygous embryos. These gene dosingdependent cascade effects suggest that the 1 NKA is an important upstream regulator but not a determinant of neurogenesis like Ngn1/2 (32) or a key receptor mechanism like Wnt is.

Quantitative data are presented as means SEM from at least six independent experiments. *P < 0.05, **P < 0.01 versus WT control.

As a control, we also assessed the expression of different isoforms of NKA and caveolin-1. As depicted in fig. S5, no changes were detected in the expression of the 1 isoform of the NKA. This is expected, as the mutations were only expressed on exon 4. Previous reports have demonstrated that, in addition to the 1 isoform, neurons also express the 3 isoform, while muscle and glial cells express the 2 isoform of the NKA (9). No difference was observed in the expression of 3, while the expression of 2 was too low to be measured. We were also unable to detect any change in the expression of caveolin-1.

The total amount of protein recognized by the anti-NKA 1 antibody is unchanged in mCBM heterozygous mouse tissues compared to that of the wild type, albeit with changes in distribution in caveolar versus noncaveolar fractions. This indicates that the CBM mutant protein is fully expressed, as observed in cells (fig. S1), and further demonstrates that a reduction of enzymatic activity is not responsible for the observed phenotype in mCBM homozygous embryos. However, because the expression of wild-type 1 in mCBM heterozygous animals is most likely reduced, the phenotypic changes we observed in these mice could be due to the reduction of wild-type 1 expression rather than the expression of CBM mutant 1. To address this important issue, we collected embryos from 1 NKA heterozygous (1+/) mice and their littermate controls (33). In contrast to mCBM heterozygotes, reduction of 1 expression alone did not change the size of embryos (Fig. 3D), head morphology, or the expression of neuronal transcriptional factors (Fig. 4E). Because NKA 1 haploinsufficiency did not phenocopy mCBM heterozygosity, it was concluded that the mCBM allele was responsible for the observed changes.

The CBM in NKA has a consensus sequence of FCxxxFGGF (fig. S6). To assess the generality of CBM-mediated regulation, we first turned to the conserveness of the CBM in animal NKA. A database search reveals that, like Wnt, the mature form of NKA (i.e., containing CBM, Na+/K+ binding sites, and subunit) is absent in unicellular organisms but present in all multicellular organisms within animal kingdom (fig. S6). Further analysis of published data confirms the coevolutionary nature of the CBM and the binding sites for Na+ and K+ in the NKA. The first indication is from the analysis of single-cell organisms. No mature form of NKA is found in these organisms (fig. S6A). However, Salpingoeca rosetta, a marine eukaryote belonging to the Choanoflagellates class, undergoes a very primitive level of cell differentiation and specialization in their life cycle and expresses a putative NKA with several conserved motifs involved in the binding of Na+/K+. On the other hand, it contains no CBM (fig. S6) and there is also no evidence that it expresses a subunit.

Second, as depicted in figs. S6 and S7, Caenorhabditis elegans, an example of a metazoan organism, expresses a mature form of NKA (eat-6) that contains binding sites for Na+ and K+ as well as the N-terminal CBM. It also expresses a couple of putative NKA such as catp-2 (34). However, they contain neither the CBM nor Na+ and K+ binding sites.

Third, although the X amino acids in the NKA CBM in invertebrates vary, only conserved substitutions occurred in this motif. This is in sharp contrast to many other membrane receptors/transducers such as Patched and G that also contain a consensus CBM (figs. S6 and S7). Within vertebrates, the CBM sequence FCRQLFGGF in NKA remains completely conserved across all species. Moreover, this sequence remains conserved in all isoforms of the subunit except for the 4 isoform, which is exclusively expressed in sperm. The 4 isoform in some species still adapts the CBM sequence found in invertebrates (fig. S6). Moreover, of a total of nine subunits found in zebrafish (35), five appear to be 1 homologs that, like the 4 isoform, contain both vertebrate and invertebrate CBM sequences.

Last, turning to the evolutionary aspect of the receptor NKA/Src complex, we found that the Src-binding NaKtide and Y260 sequences, in sharp contrast to the CBM, are only conserved in mammalian ATP1A1 (fig. S7). Therefore, the NKA/Src receptor may have evolved after the acquisition of the CBM, and hence is not a part of the fundamental regulation of animal organogenesis (fig. S3).

In short, the N-terminal CBM, like the binding sites for Na+ and K+, is conserved in all subunits of NKA in animals, even after taking into consideration gene duplications and the generation of different isoforms or homologs. Thus, we postulate that this CBM must be evolutionally conserved to enable the NKA, in parallel with its enzymatic function, to serve an important role in the origination of multicellular organisms within the animal kingdom.

Organogenesis represents a unique feature of multicellular organisms. In considering the preceding findings, we reasoned that the loss of NKA CBM would also affect embryonic development in invertebrates such as C. elegans. To test our hypothesis, we used CRISPR-Cas9 to knock in the equivalent CBM double mutations of F75A and F78A in C. elegans NKA gene eat-6 (named as syb575) (fig. S8). Similar to the impact of the expression of CBM mutant 1 NKA in mice, no homozygous worms were produced, whereas the heterozygous worms hatched normally. Moreover, by using the gene balancer nT1, we confirmed that the F75A and F78A double mutations induced embryonic lethality in syb575 homozygotes secondary to L1 arrest (Fig. 5A). Furthermore, the observed larval arrest due to the loss of the eat-6 CBM was rescued by a transgene expressing a wild-type eat-6 complementary DNA (cDNA) through an extrachromosomal array (Fig. 5B). The lethality phenotype in syb575 mutants was different from those of the eat-6 mutants defective in enzymatic (transport) activity, because while the eat-6 mutants had growth defects, they were able to grow past the L1 stage (36). An exception to this was a cold-sensitive eat-6 (ad792) mutant with severely reduced transport activity, which exhibited L1 arrest at lower temperatures similarly to the syb575 mutant worms (36). Overall, those data suggest that both CBM-mediated signaling and ion transport activity by the NKA are essential to full-scale organogenesis in C. elegans.

In short, our data indicate that loss of the NKA CBM results in defective organogenesis in both mice and C. elegans. This, together with our finding that the NKA CBM is conserved in all NKA regardless of isoform or homolog, indicates that the NKA was originally evolved as a dual functional protein in multicellular organisms, and that it represents a primordial and common mechanism for regulating stem cell differentiation and early stage of organogenesis in animals.

Turning now to even more general features of the CBM in organogenesis, we searched for the plant plasma membrane H-ATPase that functions equivalently to the animal NKA. Like the NKA, the plant plasma membrane H-ATPase also contains a sequence motif at the first transmembrane segment that is in accordance with the consensus CBM. This motif is completely conserved from blue algae to land plants but does not exist within yeast and bacteria (fig. S6).

To assess the human relevance of our findings, we used CRISPR-Cas9 gene editing to generate the same mutations in human induced pluripotent stem cells (iPSCs) (fig. S9). As depicted in Fig. 5C, the expression of mutant CBM 1 reduced the colony formation ability of human iPSCs. Concomitantly, this was accompanied by a significant reduction in the expression of stemness markers (both Nanog and Oct4), and transcriptional factors controlling germ layer differentiation (gene MIXL and T for mesoderm, OTX2 and SOX1 for ectoderm, and GATA4 and SOX17 for endoderm) (Fig. 5D). These findings confirm an essential role of the NKA CBM in the regulation of stem cell differentiation and suggest the potential utility of targeting the NKA for improving tissue regeneration.

The canonical Wnt pathway is made of multiple components localized in the plasma membrane and cytosol (2, 3). Functionally, this pathway is critically important in animal organogenesis (2, 37). For example, it plays an essential role in the establishment of neurogenic niches and regulates the differentiation of neural stem cells into neuroblasts during organogenesis by regulating the expression of transcriptional factors Ngn and NeuroD (37, 38). Thus, we were prompted by the observed neural defects in mice to test whether the expression of the CBM mutant 1 NKA affects Wnt/-catenin signaling.

In the first set of studies, we examined the cellular distribution of -catenin in LW-mCBM cells. As depicted in Fig. 6A, confocal imaging analysis showed that -catenin was distributed away from the plasma membrane in a vesicle-like form in LW-mCBM cells. To verify this finding, we fractionated the cell lysates as performed in Fig. 3B and observed that -catenin, like Src and caveolin-1, moved from the low-density fractions to high-density fractions when compared to control cells (Fig. 6B). Control experiments showed no changes in the expression of E-cadherin, glycogen synthase kinase3 (GSK-3), LRP5/6 (Low-density lipoprotein receptor-related protein 5 and 6), and -catenin in LW-mCBM cells (Fig. 6C).

(A) -Catenin staining of AAC-19 and LW-mCBM at basal level (n = 5). Blue arrow indicated -catenin signal in the cytoplasm of cells. (B) Sucrose gradient fractionation of -catenin in AAC-19 and LW-mCBM cells (n = 3). **P < 0.01. (C) Western blot analysis of Wnt/-catenin signaling proteins in AAC-19, LX-2, and LW-mCBM cells from at least six independent experiments. Two samples from each cell lines are presented. (D) Wnt3a induced TOPFlash luciferase report assay in AAC-19 and LW-mCBM (n = 8). ***P < 0.01. (E) Wnt3a induced expression of Wnt/-catenin targeting genes (n = 8). **P < 0.01. (F) Wnt3a induced TOPFlash luciferase report assay in AAC-19, LX-2, and LW-mCBM cells (n = 4). ***P < 0.01.

To test whether these changes in -catenin distribution alter the function of canonical Wnt signaling, we conducted a TOPFlash luciferase activity assay (39). Cells were transiently transfected with the reporter plasmid, exposed to Wnt3a conditional medium, and then subjected to TOPFlash luciferase assays. As shown in Fig. 6D, while Wnt3a induced a greater than 35-fold increase in luciferase activity in AAC-19 cells, it only produced a fourfold increase in LW-mCBM cells, which equates to an approximate 90% reduction in the dynamics of Wnt activation. To further test the impact of the CBM mutation on Wnt signaling, we examined the effects of Wnt3a on the expression of Wnt target genes. Cells were exposed to Wnt3a for 6 hours and subjected to RT-qPCR analysis. As depicted in Fig. 6E, while Wnt3a increased the expression of c-Myc, Lef, and NKD1 expression in AAC-19 cells, it failed to do so in LW-mCBM cells.

On the basis of the above observations, we reasoned that the NKA CBM might play an essential role in the dynamic regulation of Wnt signaling. We therefore analyzed Wnt signaling in our LX-2 cell line. This cell line was made by the same strategy used for the generation of LW-mCBM cells, and it expresses essentially just the 2 isoform (40). We have observed that 2 NKA, like CBM mutant 1, maintains cellular pumping capacity but is unable to signal via Src like a wild-type 1 NKA (40). However, unlike CBM mutant 1, 2 does contain the same CBM at the N terminus (fig. S6). As depicted in Fig. 6F, expression of the 2 isoform produced a rescue of Wnt signaling dynamics when compared to that in LW-mCBM cells, which reinforces the idea that the NKA CBM is key to the dynamics of Wnt signaling. Like in LW-mCBM cells, no change in -catenin expression was noted in LX-2 cells. However, compared to LW-mCBM cells, caveolin-1 expression was decreased in LX-2 cells, while ERK activity was increased (Fig. 6C). Together, these findings suggest that the conserved NKA CBM is essential for regulating Wnt signaling, which is independent of the pumping or CTS (ardiotonic steroid)activated Src-dependent signaling transduction.

To see whether there is evidence of Wnt signaling defects in mCBM homozygous embryos, we examined the RNAseq data using a tool kit of pathway analysis. As depicted in fig. S10, Wnt signaling appears to be defective at the transcriptional level. First, the expression of one of the Wnt receptors [Frizzled homolog 5 (Fzd5)] and one of the Wnt ligands (Wnt7b) was down-regulated (fig. S10A). Second, the Wnt/-catenin signaling inhibitor, secreted frizzled-related protein 5 (Sfrp5), was up-regulated in mCBM homozygous embryos. Third, the -catenin destruction complex component adenomatosis polyposis coli (APC) was down-regulated in mCBM homozygous embryos. All these defects in Wnt signaling were confirmed by RT-qPCR analysis of both wild-type and mCBM homozygous embryos at E9.5 (fig. S10B). In addition, APC down-regulation was also observed at the protein level in mCBM iPSCs (fig. S10C). Last, the defect in Wnt signaling was further substantiated by the altered expression of Wnt downstream target genes. As shown in fig. S10B, the expression of Lef and NKD1 was significantly reduced in mCBM homozygous embryos. The expression of c-Myc was too low to be detected.

Together, these data provide strong support to the notion that the CBM is a key to the regulation of Wnt by the NKA. We hypothesize that this critical function of the NKA CBM may explain why the CBM is conserved in all four subunit isoforms of the NKA. It is important to mention that the specific molecular defects in Wnt signaling that we have identified were tested in epithelial cells, a model we have previously used to characterize 1-specific signaling functions (16, 41). In view of the cell/tissue specificity of both NKA expression and subunit assemble (42) and Wnt signaling (13, 37), it is likely that this mechanism does not fully explain the Wnt signalingrelated defects in embryogenesis.

The enzymatic function of NKA coordinates the transmembrane movement of Na+/K+, which is essential for the survival of individual animal cells. At the tissue/organ level, the ATP-powered transport of Na+/K+ by the NKA is required for neuronal firing, muscle contraction, and the formation and functionality of epithelia and endothelia. The NKA was found to be essential for forming septate junction in Drosophila melanogaster (43, 44) via a regulatory mechanism independent of its ion-pumping activity. Here, we reveal an additional fundamentally important role of NKA in the regulation of signal transduction through a separate functional domain (CBM) unrelated to its enzymatic activity.

Our findings raise the question of why NKA acquired the CBM in addition to its binding sites for Na+ and K+. One possible explanation for this is that the additional functionality in NKA (fulfilled by the CBM) evolved for the purpose of regulating stem cell differentiation and organogenesis in multicellular organisms. Two observations support this hypothesis. First, both Wnt and NKA are present in the first multicellular organisms within the animal kingdom and are evolutionally conserved ever since. Thus, it is likely that the NKA and Wnt work in concert to enable stem cell differentiation and organogenesis in animals. Second, while Wnt is key to the cellular programs of stemness and cell lineage specification (2), it does not directly participate in cell lineagespecific activities of newly differentiated cells. Instead, this particular function might be fulfilled by the NKA. Conceivably, the NKA could have been evolved, as exemplified by the mitochondrial cytochrome c in ATP generation, to bring together two seemingly unrelated processes (i.e., Wnt signaling regulation via the CBM and ion transport through Na+ and K+ binding) into one signaling circuitry, which is critical to the dynamic regulation of transcriptional factors that are required for organogenesis in a temporally and spatially organized manner. Needless to say, this hypothesis remains to be tested. In addition, other important signaling pathways such as Notch and Sonic Hedgehog may also be regulated by NKA.

It is also of interest to note the evolutionary conserveness of the CBM in the plant plasma membrane H-ATPase. Like its counterpart within the animal kingdom, the plasma membrane H-ATPase is essential for plant organogenesis (45). Unlike the NKA, the plasma membrane H-ATPase exists in single-celled organisms such as yeast, and their ion-pumping function is regulated by similar mechanisms (46). However, yeast, with no use for cellular machinery needed for organogenesis, does not contain the H-ATPase with conserved CBM. Moreover, we also observed that no CBM exists in the plasma membrane Ca-ATPase (fig. S6), both of which belong to the same type II P-type ATPase family as the NKA. While the Ca-ATPase is a more ancient protein than the NKA, as its expression can be found in unicellular organisms, the H/K-ATPase appeared later than the NKA, at some point during the development of vertebrates. Thus, we suggest that the NKA may have evolved from a P-ATPase of unicellular organisms via the gain of both the CBM and Na+/K+ binding sites. In contrast, the H/K-ATPase may have evolved from the NKA, losing not only the Na+ binding site but also the CBM.

We have shown a direct interaction between the NKA and caveolin-1 (8, 17), which has been independently confirmed (47). The loss of the CBM significantly reduced the interaction between NKA and caveolin-1 as revealed by multiple assays. In addition to caveolin-1, we and others have reported several signal transductionrelated interactions (48). Of these, the potential interaction between 1 NKA and Src has attracted the most attention, especially in the past 10 years (7). While most studies indicated an important role of Src in CTS-activated signal transduction via 1 NKA, several publications have questioned whether 1 NKA interacts with Src directly to regulate Src functionality (49, 50). While this important difference remains to be experimentally addressed, we would like to point out the following facts. First, while we recognize the merit of using purified protein preparation to study protein interaction, it is important to recognize the limitation of using purified Src from bacterial expression system because they are heterogeneously phosphorylated. Second, we have reported multiple lines of evidence that support a direct interaction between 1 NKA and Src, including the identification of isoform-specific Src interaction, the mapping of potential Src-interacting sites in the 1 isoform, and the development of pNaKtide as Src inhibitor and receptor antagonist. These findings have substantially increased our understanding of 1 NKA/Src interaction in cell biology and animal physiology. It is important to mention that several groups not associated with us have successfully used pNaKtide to block ouabain and NKA signaling in vitro and in vivo (2326, 51). While our group and others continue to characterize the molecular basis and biological function of the NKA/Src receptor complex, we propound that the question of NKA/caveolin-1 interaction is a more pressing one in the context of this study. The role of CBM in caveolin-protein interaction and caveolae-related signaling is still debated (41, 52, 53).

Last, we conclude from these interesting findings that the NKA is not just an ion pump or a CBM-directed regulator but a critical multifunctional protein. This whole functionality underlies a hitherto unrecognized common mechanism essential for stem cell differentiation and organogenesis in multicellular organisms within the animal kingdom. Moreover, many recent studies also support the concept that the 1 NKA has acquired more functional motifs (e.g., Src-binding sites for the formation of NKA/Src receptor complex) during evolution. In addition, we have demonstrated that either knockdown of 1 NKA or the expression of an N-terminal fragment containing the CBM of the 1 subunit was sufficient to attenuate purinergic calcium signaling in renal epithelial cells (54). The 1 NKA is also found to be essential for CD36 and CD40 signaling in macrophages and renal epithelial cells (55, 56). Aside from the profound biological and fundamental implications, the previously unidentified NKA-mediated regulation of Wnt signaling through its N-terminal CBM may have substantial implications in our understanding of disease progression. The rapidly increasing appreciation of Wnt signaling in the pathogenesis of cancer and cardiovascular diseases (2, 3, 38) underlies the potential utility of NKA as a multidrug target (12, 22, 57, 58).

The impact of COVID-19 pandemic can be felt across the Healthcare Industry The growing inability in the production and manufacturing processes, in the light of the self-quarantined workforce has caused a major disruption in the supply chain across the sector. Restrictions encouraged by this pandemic are obstructing the production of essentials such as life-saving drugs.

The nature of operation in Pharmaceuticals plants that cannot be easily stopped and started, makes the operational restrictions in these plants a serious concern for the industry leaders. Restricted and delayed shipments from China have created a price hike in the raw materials, affecting the core of the Healthcare Industry.

Central nervous system comprises brain and spinal cord, and is responsible for integration of sensory information. Brain is the largest and one of the most complex organs in the human body. It is made up of 100 billion nerves that communicate with 100 trillion synapses. It is responsible for the thought and movement produced by the body. Spinal cord is connected to a section of brain known as brain stem and runs through the spinal canal. The brain processes and interprets sensory information sent from the spinal cord. Brain and spinal cord serve as the primary processing centers for the entire nervous system, and control the working of the body.

Neuroprosthetics improves or replaces the function of the central nervous system. Neuroprosthetics, also known as neural prosthetics, are devices implanted in the body that stimulate the function of an organ or organ system that has failed due to disease or injury. It is a brain-computer interface device used to detect and translate neural activity into command sequences for prostheses. Its primary aim is to restore functionality in patients suffering from loss of motor control such as spinal cord injury, multiple sclerosis, amyotrophic lateral sclerosis, and stroke. The major types of neuroprosthetics include sensory implants, motor prosthetics, and cognitive prosthetics. Motor prosthetics support the autonomous system and assist in the regulation or stimulation of affected motor functions.

Similarly, cognitive prosthetics restore the function of brain tissue loss in conditions such as paralysis, Parkinsons disease, traumatic brain injury, and speech deficit. Sensory implants pass information into the bodys sensory areas such as sight or hearing, and it is further classified as auditory (cochlear implant), visual, and spinal cord stimulator. Some key functions of neuroprosthetics include providing hearing, seeing, feeling abilities, pain relief, and restoring damaged brain cells. Cochlear implant is among the most popular neuroprosthetics. In addition, auditory brain stem implant is also a neuroprosthetic meant to improve hearing damage.

North America dominates the global market for neuroprosthetics due to the rising incidence of neurological diseases and growth in geriatric population in the region. Asia is expected to display a high growth rate in the next five years in the global neuroprosthetics market, with China and India being the fastest growing markets in the Asia-Pacific region. Among the key driving forces for the neuroprosthetics market in developing countries are the large pool of patients, increasing awareness about the disease, improving healthcare infrastructure, and rising government funding in the region.

Increasing prevalence of neurological diseases such as traumatic brain injury, stroke and Parkinsons disease, rise in geriatric population, increase in healthcare expenditure, growing awareness about healthcare, rapid progression of technology, and increasing number of initiatives by various governments and government associations are some key factors driving growth of the global neuroprosthetics market. However, factors such as high cost of devices, reimbursement issues, and adverse effects pose a major restraint to the growth of the global neuroprosthetics market.

Innovative self-charging neural implants that eliminate the need for high risk and costly surgery to replace the discharge battery and controlling machinery with thoughts would help to develop opportunities for the growth of the global neuroprosthetics market.

Spinal Cord Injury And Stem Cells: New Perspectives …

By daniellenierenberg

However, stem cells could provide the answer to treating and repairing spinal cord injuries.

A British professor, Geoffrey Raisman, undertook research which showed that specific stem cells could enable a paralysed man to walk again.

He used stem cells called olfactory ensheathing cells (OECs) from the nose of a patient and transplanted them into the spinal cord. OECs are unique cells which are part of the sense of smell. They allow nerve fibres in the olfactory system to constantly regenerate. Prof Raisman proved that broken nerve fibres in the spinal cord could repair themselves by using OECs that were transplanted into the spinal cord of the patient. These specific stem cells (OECs) facilitated the growth of the ends of severed nerve fibres and caused them to join together.

A doctor in Portugal also transplanted olfactory stem cells to treat spinal cord injury in over 100 patients. These studies showed that a few patients were able to regain at least limited motor function and sensation after transplantation.

Although its early days, these studies show that neuronal type stem cells (NSCs) hold great promise to treat various neurodegenerative diseases and injuries to the spinal cord. Stem cells possess the ability to differentiate into many types of neural cell, depending upon their environment and the stimulus that is provided.

At present there are 55 clinical trials investigating the application of stem cells in spinal cord injury. These trials are studying various sources of stem cells including mesenchymal stem cells, bone marrow, umbilical cord tissue and adipose tissue derived stem cells.

(Marsala M, et.al. Spinal parenchymal occupation by neural stem cells after subpial delivery in adult immunodeficient rats. STEM CELLS Translational Medicine, 2019; 9 (2): 177 DOI: 10.1002/sctm.19-0156)

Please note: Stem cell therapy for spinal cord injury is in a research phase, and is not an established therapy.

Cord blood stem cell therapy for spinal cord injury is not available in South Africa.

Stem cell research for spinal cord injury

By daniellenierenberg

Spinal cord injury (SCI) involves damage to the area that can cause an impairment of loss of muscle control, movement and sensation. Currently, patients with injury to the spinal cord are managed with physical therapy, occupation therapy and other rehabilitation methods to cope with the physical changes.

However, stem cell research may present a new approach to the management of this patient group, ing for a potential improvement in the symptoms of the condition, such as incontinence, muscular control and sexual function.

Stem cells used in the treatment of SCI may come from various sources, including autologous mesenchymal CD34+ cells from own bone marrow, allogeneic mesenchymal cells from the human umbilical cord tissue or adipose tissue.

The bone marrow cells are taken from both hips of the patient, who is sedated with light general anesthetic. The cells are then tested for quality and bacterial contamination before they can be used in the research. Likewise, cells from umbilical cords are taken from healthy births and must pass rigorous screening prior to being passed for use in trials.

Scientific research conducted in animals with spinal cell injury has investigated the utility of stem cells in the repair of the injury. As a result of this research, a general understanding of the role that stem cells could play has been established. This includes:

Mesenchymal stem cells, also known as stromal stem cells, are a topic of interest in the research for treatment of spinal cord injury. The theory is for the stem cells to provide protection to and aid growth of the cells in the region of the injured spinal cord.

The safety and efficacy of different stem cell types have been investigated in several different studies. Various methods of administration have been trialed, including injection into the spine, the vein or the skin.

There has also been some research focused on embryonic stem cells in the management following spinal cord injury.

One study observed the effect of an injection of precursors of oligodendrocytes, to form the myelin sheath around the axons. However, after four patients were treated with the cells and observed for signs of restored nerve signaling, the study was discontinued. The belief that embryonic stem cells may be promising for spinal cord injury was not tainted.

Another study investigated the effect of hES cell-derived oligodendrocyte progenitor cells when injected into the site of thoracic spinal cord injury. Of five patients, none experienced serious side effects, and imaging tests revealed that the volume of injury was reduced in 80% of patients.

At this point in time, there is insufficient scientific evidence to recommend the used of stem cells for spinal cord injury as a routine practice. The technique is promising, however, offering the possibility of healing and the improvement of the symptoms, which is in contrast to the current practice that recommends coping mechanisms without a definitive cure or improvement.

For this reason, scientific research is likely to continue in the future in the hope of finding a suitable method to improve the quality of life for patients with spinal cord injury.

Coronavirus health scams are rampant, with businesses taking advantage of peoples fears to sell all sorts of unproven products for the prevention and treatment of COVID-19. Some of these snake oil cures are innocuous, such as elderberry juice, but others can be harmful, such as colloidal silver.

Among the products with considerable potential for harm are unproven stem cell therapies. Unfortunately, the emergence of this particular line of sham COVID-19 treatments isnt all that surprising. For more than a decade, businesses have been aggressively pitching unsubstantiated and unlicensed stem cell products to vulnerable and often desperate individuals with illnesses or injuries for which no known treatment exists, such as Alzheimers disease, amyotrophic lateral sclerosis (ALS), chronic obstructive pulmonary disease (COPD) and spinal cord injuries. The results have sometimes been deadly.

There are some medical conditions for which stem cell therapies have been shown to be safe and effective, but they are few in number mostly cancer and several blood and immune disorders.

Leigh Turner, a bioethicist at the University of Minnesota, has been investigating the direct-to-consumer marketing of spurious stem cell therapies and related exosome products in the United States for nearly a decade. In an article published recently in the journal Cell Stem Cell, Leigh describes the latest twist in this cynical saga: how some stem cell businesses are seizing the [COVID-19] pandemic as an opportunity to profit from hope and desperation.

MinnPost spoke with Turner late last week about what he found when researching that paper. The following is an edited transcript of the interview.

MinnPost: Companies seem to be using the same kind of marketing strategies to sell unproven stem cell therapies for COVID-19 as they have for other medical conditions.

Leigh Turner: Yes. These are opportunistic businesses. They look for marketplace opportunities, ways to generate e-revenue streams. And the COVID-19 pandemic is another business opportunity. Its not like theyve pivoted away from what they did in the past. If they were marketing stem cell treatments for Parkinsons disease, or ALS or spinal injuries, they havent stopped doing that. Theyve just added that theyve now got a stem cell treatment or an exosome therapy to treat or prevent COVID-19.

MP: They seem to be marketing their products primary as immune system boosters.

Leigh Turner

MP: At least one company is telling people that they should bank their stem cells to use as a treament if they get infected with the coronavirus.

LT: There are several business models at play right now. One is, come on in and get your stem cell immune booster to reduce your chances of getting COVID-19. They may also claim it will reduce your symptoms should you get it. Another marketing pitch is a bit more cautious. It says that if you come in now when youre in good health, they will bank your cells. Youll pay for the initial extraction of cells and also monthly or yearly for banking. The company then claims that should you fall ill with COVID-19 down the road, youll have those healthy cells available for you to use. Of course, they dont offer a lot of detail about how the cells would actually help you. You just supposed to take it for granted that they will.

MP: Theres no evidence of that.

LT: No. Its all just pseudoscience. But there is a meaningful hypothesis behind it. Thats how these businesses operate by fusing science with pseudoscience, credible research with junk claims.

MP: What is that hypothesis?

LT: There are companies and academic institutions right now that are interested in testing stem cell products, but not as immune boosters, not to prevent COVID-19 and not to eliminate the virus if someone gets infected. The studies right now are focusing on a very particular population of people with COVID-19 those who are typically in ICUs, suffering from acute respiratory distress syndrome. The hypothesis is that if certain types of stem cell products are administered to those people, we may be able to reduce inflammation in the lungs and help shorten the illness. But its a hypothesis.

MP: A good one?

LT: Its not an outrageous hypothesis. If you look at the existing literature, there have been studies done in the past that used stem cells for lung and respiratory disease. So far, those studies suggest that if you use clinical-grade stem cells and if you do it in a very rigorous way the safety profile is pretty good. But none of those studies has established extensive evidence of efficacy yet. Ideally, what you want is carefully designed, carefully conducted clinical trials testing that hypothesis and generating that evidence. These businesses the ones marketing stem cell therapies directly to individuals are not part of that scientific world.

MP: How do those businesses pull their customers in? How do they find them?

LT: They are typically big on social media. Im talking generally here, but they have Twitter accounts. They have YouTube channels. They have a Facebook page. Theyre not just putting up a website and hoping that somebody walks in the door. They hire social media marketing companies. They use marketing firms. They have pretty sophisticated marketing strategies that are tailored to particular demographics. It may be that they are targeting an elderly population, for example, because if youre interested in reaching people with COPD, youre not going to be trying to find 18-year-olds. Some businesses here in Minneapolis and elsewhere will have what they describe as educational seminars, which are basically infomercials. They are marketing events. They will try to get people to come to a convention center, a hotel [conference] room or a restaurant. Everything is free, but what theyll do is use hard-sell sales tactics to get people to commit, to write a check. Often theyll tell people that if they sign on today, theyll knock $2,000 or so off the price. But, of course, theyre not holding these events right now. They cant have these public gatherings.

MP: So, how are they selling people these products now, during the pandemic?

LT: More of it is happening online. One company, for example, uses a graduated pricing model. If its one person, its one price point. If its you and a family member, you both get a break on the procedure. And if its you and two additional family members, the price goes down even more. They use these things to try to get people to come in the door. One company in California has adapted to the pandemic in a different way. They have a do-it-yourself model. You dont have to even come into the clinic. You can buy their kit, and they ship it to your home. You then do the procedure at your dining room table.

MP: These stem cell products and treatments are quite expensive.

LT: Yes, some of the businesses Ive look at charge tens of thousands of dollars, although thats not necessarily for treating COVID-19. For COVID-19, it appears to be in the thousands-of-dollars category. In some cases, we dont know. The businesses can be pretty cagey. In some cases, they try to size up the customer and figure out how much they can extract from that person.

MP: Government agencies are cracking down on some of these stem cell businesses.

LT: The FDA (Food and Drug Administration), FTC (Federal Trade Commission) and Department of Justice have said that theyre going to be aggressive with dealing with these scams. And they have. Some businesses have already received letters from the regulators. That may be having a deterrent effect during the pandemic. Some businesses may want to jump in, but are afraid to do so. They may be waiting to see what happens before they take the chance.

MP: But the regulatory agencies are obviously not finding all of the businesses marketing unproven COVID-19 therapies.

LT: There is a lot of marketing fraud. And sometimes its quite challenging to figure out whats going on. Some of the clinics that I looked at didnt say, Were offering an immune booster for COVID-19. It was more just chatter. Clinics would put up a seven-minute video from one of their doctors about COVID-19 and emerging stem-cell research coming out of China, saying it was really encouraging. Then they would say, If you have any questions about stem cells and COVID-19, give us a call. So, whats the takeaway when a business does that? Does that mean they are selling stem cell treatments for COVID-19? Or are they just trying to get people to call? Its hard to know whats happening. If I had to guess, I say its a workaround. The businesses dont want to put it on their website, because thats too easy for someone from the FTC or the FDA to find. If they just put up a video, they can say theyre not marketing anything, that it was just meant to be educational.

MP: These businesses seem to rely on anecdotal cases or really small studies from China to support their claims.

LT: They use China in a couple of different ways. There was a case report, for example, that was published as a preprint. It wasnt published by a journal. It hasnt gone through peer review. It was just a preprint that someone put online. Its the case of a single individual with COVID-19 who received stem cells. Thats been written up in a very hyperbolic way, when really, its just a case report. Its one person. Some people get COVID-19 and recover anyway. You cant draw any conclusions from it about stem cells being efficacious, but its been written up that way. There was another study, very preliminary research, in which mesenchymal stem cells were administered to seven individuals with COVID-19 with various degrees of severity. A placebo was given to three individuals. The article doesnt provide the source of the stem cells. Nor does it provide much insight about the individuals who were given placebos, although they appear to be about 10 years older than [those receiving the stem cells]. It raises some interesting questions. It provides a basis for further research. But, unfortunately, some of the news media reports have been hyperbolic. Stem cell businesses use both these papers when marketing directly to consumers. They refer to these studies, and they also attach themselves to the bubbly media coverage.

MP: Consumers need to know that these products can be dangerous.

LT: Yes. The danger comes in several forms. Part of it is that these are financial scams lifting money off people who are worried and anxious. But, also, giving someone a product that hasnt been carefully tested in well-designed clinical trials raises a lot of concerns. Some businesses have released contaminated stem cell products into the marketplace. People end up getting infections and having to be hospitalized. It can be a very serious thing. Theres also the possibility that the wrong type of cell goes to the wrong part of the body and causes harm. When a company claims, for example, that a stem cell product will regenerate lung tissue and be an immune booster, one thing I would worry about is pulmonary embolisms. If someone is being given something that hasnt been thoroughly tested, its hard to know what would go wrong, but its easy to know something could go wrong.

FMI: Youll find the article on Cell Stem Cells website.

Spinal Cord Treatment Problems Site not the Cells …

Therapeutic Activities of Engrafted Neural Stem/Precursor Cells Are Not Dormant in the Chronically Injured Spinal Cord

From Stem Cells

Neural stem or precursor cells (NSPCs) have tremendous promise for use in cell-based therapies for the treatment of spinal cord injury (SCI) as they have been shown to provide trophic support following transplantation, allowing modification of the host environment to allow some endogenous regeneration and repair in animal models (Aboodyet al,Barnabe-Heider and Frisen, andMartino and Pluchino). However, few studies have assessed their role in the chronic phase of SCI (Tetzlaffet al) and any correlation to microenvironmental factors (Thuretet al), which is potentially important for the behaviour of transplanted NSPCs. Now, in a study published inStem Cellsfrom the laboratory of Seiji Okada at Kyushu University, Japan,Kumamaruet alcombine flow-cytometric isolation and RNA-Seq to analyse the transcriptome of NSPCs transplanted into SCI during the chronic phase, and have demonstrated that while the cells have a positive therapeutic effect, the refractory state of the chronically injured spinal cord hampers locomotory recovery.

To determine the chronic phase of SCI, a time course of the change in the number of inflammatory cells until 3 months after SCI was assessed. Neutrophil infiltration peaked at 12 hours and subsequently decreased, microglia increased and peaked at 6 weeks, while macrophages and monocytes first peaked at 12 hours and then again at 6 weeks. Gene expression analysis over the same time period found that levels of pro-inflammatory factors, anti-inflammatory factors, CXC chemokine ligands and CC chemokine ligands and growth and neurotrophic factors were very different between the acute (enriched in inflammatory cytokine/chemokines and neurotrophic factors) and the chronic (enriched in growth factors) stages of SCI. Next, Luciferase and GFP-labeled NSPCs were transplanted 3 months after SCI, where long-term cell viability was observed and graft survival rate of around 17% was observed at 42 days after transplantation. Transplanted NSPCs migrated up to 4mm rostrally or caudally from the graft site and had extended fine cellular processes. Chondroitin sulfate proteoglycans (CSPGs) are potent inhibitors of transplanted cell migration and survival and have been linked to transplant failure during the chronic phase (Karimi-Abdolrezaee et al). Analysis found that while CSPGs were abundant during the sub-acute phase of SCI, this reduced to normal levels at three months.

Subsequent RNA-Seq analysis of NSPCs analysed at 7 days after transplantation during the acute, sub-acute, and chronic phases of SCI found, as observed previously (Kumamaru et al), that transcriptional activity is reduced in NSPCs transplanted into the acutely injured spinal cord compared to those transplanted into nave spinal cords, however this reduction was not observed for the sub-acute and chronic phases, and increased transcriptional activity was observed in chronically transplanted NSPCs. Principal component analysis then suggested that sub-acutely injured spinal cords may promote the oligodendrocyte differentiation of transplanted NSPCs whereas chronically injured spinal cords promoted neuronal differentiation. Analysis of differentiation-associated gene expression found that chronically injured spinal cords were permissive for the differentiation of engrafted NSPCs with overexpressed genes representing neurogenesis and neuronal differentiation. Oligodendrocyte generation by engrafted NSPCs was not however inhibited in chronic SCI microenvironments but was more prominent in sub-acute SCI. Secreted molecules, which can act as trophic mediators, decreased markedly in acutely injured spinal cords but increased in chronically injured spinal cords. Finally, functional improvement was analysed and, while NSPC transplantation in the acute and sub-acute groups showed significantly improved functional recovery, the chronically NSPC-transplanted mice did not exhibit improved locomotor recovery.

Overall, this study shows that NSPCs which are transplanted into chronic phase SCI sites survive, are migratory, transcriptionally active, undergo neuronal and oligodendrocyte differentiation and secrete trophic factors at a level higher than expected from a refractory site, BUT, ultimately do not improve locomotor function. This suggests that the micro-environment of SCI in the chronic phase itself is the main barrier to the potential regenerative effects of NSPC transplantation. With this knowledge in hand, therapies for this type of injury will hopefully continue to evolve to a state where cell therapy and environmental modulation can work hand in hand to affect functional recovery.

Our patented technology platform has three core components:

1. Over 300 lines of human, regionally specific neural stem cells, some of which

have the potential to be used to treat serious or life-threatening diseases

through direct transplantation into the central nervous system;

2. Proprietary screening capability - our ability to generate human neural stem

cell lines provides a platform for chemical screening and discovery of novel

compounds against nervous system disorders; and

3. Small molecules that resulted from Seneca's neurogenesis screening platform

To date, our technology platform has produced two lead assets in clinicaldevelopment: our NSI-566 stem cell therapy program and our NSI-189 smallmolecule program. A component of our current strategy is out-licensing and wehave recently initiated a formal out-licensing initiative aimed at securingpartners to advance the clinical development of these two programs.

In-licensing and Acquisition Strategy

Below is a description of our clinical programs, their intended indication andcurrent stage of development:

Motor Deficits Due to Ischemic Stroke

Amyotrophic Lateral Sclerosis

Chronic Spinal Cord Injury

Clinical Experience with NSI-566

Amyotrophic Lateral Sclerosis

Pre-Clinical Experience with NSI-566 and other candidates in our stem cellpipeline

NSI-189 (Small Molecule Pharmaceutical Compound)

Major Depressive Disorder (MDD)

Clinical Experience with NSI-189

Preclinical Experience with NSI-189

NSI-189 has shown promise in preclinical studies evaluating its impact in animalmodels for a number of different disease indications, including:

1. Ischemic stroke-in 2017 Tajiri and colleagues published a manuscript

reporting that NSI-189 ameliorated motor and neurological deficits in a

rodent model of ischemic stroke (Tajiri et al., J Cell Physiol 2017,

232(10):2731-2740)

2. Radiation-induced cognitive dysfunction-in 2018 Allen and colleagues

published a manuscript reporting that NSI-189 treatment could reverse

cognitive deficits in rats caused by cranial irradiation, a model of cranial

radiotherapy in the treatment of brain tumors (Allen et al., Radiat Res 2018,

189(4):345-353).

3. Angelman syndrome-in 2019 Liu and colleagues published a manuscript reporting

that NSI-189 reversed impairments in cognitive and motor deficits in a rodent

model of Angelman syndrome and increased synaptic strength in sections of

brains taken from these animals (Liu et al., Neuropharmacology 2019,

144:337-344). Angelman syndrome (AS) is a rare congenital genetic disorder

caused by a lack of function in the UBE3A gene on the maternal 15th

chromosome. It affects approximately one in 15,000 people - about 500,000

individuals globally. Symptoms of AS include developmental delay, lack of

speech, seizures, and walking and balance disorders.

4. Diabetes-associated peripheral neuropathy-in 2019 Jolivalt and colleagues

published a manuscript reporting that NSI-189 mitigated or reversed

disease-associated central and peripheral neuropathy in two rodent models of

diabetes (Jolivalt et al., Diabetes 2019, (11):2143-2154). Improvements

resulting from NSI-189 treatment were seen on multiple sensory and cognitive

About ALS

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrigs disease, is a progressive neurodegenerative disease impacting nerve cells in the brain and spinal cord. ALS breaks down nerve cells, reducing muscle function and causing loss of muscle control. ALS can be traced to mutations in over 25 different genes and is often caused by a combination of multiple sub-forms of the condition. Its average life expectancy is three years, and there is currently no cure for the disease.

About QurAlis Corporation

QurAlis is developing precision therapeutics for ALS, a terminal disease that causes muscle paralysis through degeneration of the motor system. We are digging deep into the root causes of the multiple sub-forms of this destructive disease and focus our programs on tackling specific disease-causing mechanisms.
