Stem Cells Attenuate the Inflammation Crosstalk Between Ischemic Stroke and Multiple Sclerosis: A Review
Cell Transplant. 2023 Jan-Dec;32:9636897231184596. doi: 10.1177/09636897231184596.ABSTRACTThe immense neuroinflammation induced by multiple sclerosis (MS) promotes a favorable environment for ischemic stroke (IS) development, making IS a deadly complication of MS. The overlapping inflammation in MS and IS is a prelude to the vascular pathology, and an inherent cell death mechanism that exacerbates neurovascular unit (NVU) impairment in the disease progression. Despite this consequence, no therapies focus on reducing IS incidence in patients with MS. To this end, the preclinical and clinical evidence we review here argues f...

Effects of Neurotrophic Factors in Glial Cells in the Central Nervous System: Expression and Properties in Neurodegeneration and Injury
Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

3K3A –activated protein C stimulates postischemic neuronal repair by human neural stem cells in mice
Nature Medicine 22, 1050 (2016). doi:10.1038/nm.4154 Authors: Yaoming Wang, Zhen Zhao, Sanket V Rege, Min Wang, Gabriel Si, Yi Zhou, Su Wang, John H Griffin, Steven A Goldman & Berislav V Zlokovic Activated protein C (APC) is a blood protease with anticoagulant activity and cell-signaling activities mediated by the activation of protease-activated receptor 1 (F2R, also known as PAR1) and F2RL1 (also known as PAR3) via noncanonical cleavage. Recombinant variants of APC, such as the 3K3A-APC (Lys191–193Ala) mutant in which three Lys residues (KKK191–193) were replaced with alanine, and/or its other mutan...

Mesenchymal Stem Cells: Potential in Treatment of Neurodegenerative Diseases.
Abstract Mesenchymal Stem Cells or Marrow Stromal Cells (MSCs) have long been viewed as a potent tool for regenerative cell therapy. MSCs are easily accessible from both healthy donor and patient tissue and expandable in vitro on a therapeutic scale without posing significant ethical or procedural problems. MSC based therapies have proven to be effective in preclinical studies for graft versus host disease, stroke, myocardial infarction, pulmonary fibrosis, autoimmune disorders and many other conditions and are currently undergoing clinical trials at a number of centers all over the world. MSCs are also being exte...

Case report: Central nervous system involvement of human graft versus host diseaseReport of 7 cases and a review of literature
We report 7 cases of CNS-GvHD among which two had histological-proven disease. We reviewed 32 additional cases of CNS GvHD published in literature since 1990. In this cohort, 34 patients were transplanted for hematologic malignancies, and 5 for non-malignant hematopoiesis disorders. Of these patients, 25 had a history of chronic GvHD and immunosuppressive treatment had been decreased or discontinued in 14 patients before neurological symptoms onset. Median neurological disorder onset was 385 days [7-7320]. Patients had stroke-like episodes (n = 7), lacunar syndromes (n = 3), multiple sclerosis-like presentations (n...

Fecal Microbiota Transplantation in Neurological Disorders
Conclusions: Preliminary literature suggests that FMT may be a promising treatment option for several neurological disorders. However, available evidence is still scanty and some contrasting results were observed. A limited number of studies in humans have been performed or are ongoing, while for some disorders only animal experiments have been conducted. Large double-blinded randomized controlled trials are needed to further elucidate the effect of FMT in neurological disorders.

Stem Cell Therapy for Neurogenic Bladder Dysfunction in Rodent Models: A Systematic Review.
CONCLUSION: Partial bladder recovery has been evident after SC therapy in SCI models. Due to limitations in the number of studies in other neurological diseases, additional studies are necessary to confirm the detailed mechanism for bladder recovery. PMID: 33017895 [PubMed]

Can ‘toxic’ bilirubin treat a variety of illnesses?
Generations of medical and biology students have been instilled with a dim view of bilirubin. Spawned when the body trashes old red blood cells, the molecule is harmful refuse and a sign of illness. High blood levels cause jaundice, which turns the eyes and skin yellow and can signal liver trouble. Newborns can’t process the compound, and although high levels normally subside, a persistent surplus can cause brain damage. Yet later this year up to 40 healthy Australian volunteers may begin receiving infusions of the supposedly good-for-nothing molecule. They will be participating in a phase 1 safety trial, sponsored ...

Neuro-immune interactions of neural stem cell transplants: From animal disease models to human trials.
Abstract Stem cell technology is a promising branch of regenerative medicine that is aimed at developing new approaches for the treatment of severely debilitating human diseases, including those affecting the central nervous system (CNS). Despite the increasing understanding of the mechanisms governing their biology, the application of stem cell therapeutics remains challenging. The initial idea that stem cell transplants work in vivo via the replacement of endogenous cells lost or damaged owing to disease has been challenged by accumulating evidence of their therapeutic plasticity. This new concept covers the rem...

Autologous mesenchymal stem cells for the treatment of secondary progressive multiple sclerosis: an open-label phase 2a proof-of-concept study
Conclusions Autologous MSCs can be safely administered in secondary progressive MS with evidence to suggest structural, functional and physiological improvement following treatment consistent with neuroprotection. The transient treatment response seen implied a likely requirement for repeat infusions to sustain benefit in the long–term.

The Dance Between The Immune System and Stem Cells
We named it the  immunoLinkTM We have been testing a growing number of Clients with our Quantibody Arrays. Many of of these clients have Autoimmune Disorder Diseases. These range from Rheumatoid Arthritis to Multiple Sclerosis.These arrays are designed to precisely measure factors or markers (proteins) that are dysregulated by these diseases. We measure the levels of these biomarkers in our Clients' Blood serum. The arrays have also been used to measure the levels of markers in plasma and cell culture supernatants.Based on results, we are finding links between immune system and stem cell health. We call this the ...

Human Wharton?s jelly-derived stem cells display immunomodulatory properties and transiently improve rat experimental autoimmune encephalomyelitis.
In this study, we investigated whether WJ-MSCs possess the required properties to effectively and durably reverse these pathological hallmarks, and whether they survive in an inflammatory environment after transplantation. WJ-MSCs displayed a lowly immunogenic phenotype and showed intrinsic expression of neurotrophic factors and a variety of anti-inflammatory molecules. Furthermore, they dose-dependently suppressed proliferation of activated T cells using contact-dependent and paracrine mechanisms. Indoleamine 2,3-dioxygenase 1 was identified as one of the main effector molecules responsible for the observed T cell suppres...
