Proteins called tenascins block the regeneration of myelin by modulating the activity of oligodendrocytes, myelin-making cells of the central nervous system, a study in mouse models indicates. “Our research results open up new therapeutic approaches for the treatment of demyelinating diseases such as multiple sclerosis,” Juliane Bauch, a researcher at Ruhr-University…
Blocking a particular receptor protein of the BMP signaling pathway effectively promoted the maturation of myelin-producing cells and myelin repair in two mouse models of multiple sclerosis (MS), a study showed. Notably, these benefits, observed even after disease onset, took place in the presence of fibrinogen, a blood clotting…
A decline in the activity of the GPR17 gene is responsible for age-related brain deterioration caused by the loss of myelin, a fatty substance that surrounds nerve cells like a sheath, a mouse study discovered. Researchers identified a small molecule that rejuvenated…
Editor’s note: The Multiple Sclerosis News Today news team is providing in-depth and unparalleled coverage of the virtual ACTRIMS Forum 2021, Feb. 25-27. Go here to see all the latest stories from the conference. Factors in the cerebrospinal fluid (CSF) surrounding the brain and spinal cord change with age and can affect…
The 2020 Barancik Prize for Innovation in MS Research has been awarded to neuroscientist Dwight E. Bergles, PhD, a Johns Hopkins University professor, for his work in understanding the function of brain cells in multiple sclerosis (MS). This international prize awards $100,000 to the recipient. Administered by the National MS…
Scientists have demonstrated that stem cells derived from the skin cells of people with multiple sclerosis (MS) can grow into normal myelin-producing nerve cells, called oligodendrocytes, in a mouse model of MS. These patient-derived cells migrated throughout the brain of myelin-deficient mice, producing myelin — the fatty…
Exposure to stress before birth can worsen the clinical symptoms of multiple sclerosis (MS) during adulthood, a study in a mouse model of MS suggested. Investigators also found that prenatal stress can change the levels of a protein critical for neurological development, called…
Using a two-pronged approach, researchers were able to restore myelin on regenerated nerve fibers in a mouse model of optic nerve injury, which has implications for multiple sclerosis (MS) and other diseases associated with myelin loss, a study reported. The study, “…
Oral administration of N-acetylglucosamine (GlcNAc) — a natural simple sugar sold as a dietary supplement — prevents myelin degeneration and loss of motor function in a mouse model of multiple sclerosis (MS). Myelin, the protective sheath around nerve fibers that helps to speed transmission of signals between nerve cells, is damaged…
Anacardic acid, a compound found in cashew nuts, promoted myelin regeneration and eased neuronal damage and disability in two mouse models of multiple sclerosis (MS). These protective effects were associated with maturation of myelin-producing cells and production of IL-33, an immune-related molecule with a neuroreparative role in the central…
Transplanting human glial progenitor cells (GPCs) — brain cells able to generate myelin-producing cells — effectively led to remyelination in the brains of adult mice with myelin disorders, a study found. These results were presented at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2020, running…
Potential Therapy, Anavex 2-73, Shows Ability to Protect Neurons and Promote Myelin in Early Tests
Anavex Life Sciences‘ investigational therapy Anavex 2-73 (blarcamesine) showed an ability to protect, repair, and induce the formation of oligodendrocytes — the cells that produce the protective myelin layer around neurons — in early cell testing, researchers reported. These findings, which further establish the therapy’s potential as a treatment…
Blocking a protein called PAR1 may enhance the regeneration of myelin, the protective fatty layer that covers nerve fibers and is damaged in multiple sclerosis (MS), a mouse study shows. Therapeutic targeting of PAR1 may promote remyelination and delay MS progression, according to the study, “Blocking the Thrombin Receptor…
Metformin, a common diabetes treatment that works to mimic dietary fasting, was seen to promote remyelination in the stem cells of elderly rats, suggesting it may be useful in treating multiple sclerosis. “Metformin Restores CNS Remyelination Capacity by Rejuvenating Aged Stem Cells” was published in…
Blocking production of the low-density lipoprotein receptor-related protein 1 (LRP1) — involved in inflammatory and immune responses — specifically in myelin repair cells halts neuroinflammation and promotes myelin repair, a preclinical study shows. These results, from two mouse models of multiple sclerosis (MS), shed light on the underlying mechanisms…
NervGen Pharma announced plans to open clinical trials evaluating the potential of its lead candidate NVG-291 to treat multiple sclerosis (MS) and spinal cord injury. NVG-291 is an investigational peptide that has shown an ability to stimulate nerve regeneration following an injury in several animal models of disease.
A molecule known as Sox10 enables brain cells called astrocytes to convert into myelin-forming oligodendrocytes, a new study in mice reports. The findings suggest an approach for myelin repair in patients with multiple sclerosis (MS) and similar disorders, its researchers said. The study, “In vivo conversion of…
Blocking Protein Receptor Called M3R Seen to Promote Remyelination in Mice Model, Study Reports
Blocking a protein receptor called muscarinic type 3 (M3R) could be an effective way to promote remyelination in multiple sclerosis (MS) patients, according to a State University of New York at Buffalo (UB) study in mice. The research, “Muscarinic receptor M3R signaling prevents efficient remyelination by…
A molecule responsible for preventing the repair of white matter in the brain, a process critical to treating multiple sclerosis (MS) and cerebral palsy, has been identified. The research, “A TLR/AKT/FoxO3 immune-tolerance like pathway disrupts the repair capacity of oligodendrocyte progenitors,” was published in The Journal…
A substance that the pancreas secretes can promote the regeneration of the protective nerve-cell coating that is damaged in multiple sclerosis, a mouse study shows. The substance is fibroblast growth factor 21, or FGF21. It promotes remyelination, the renewal of the myelin sheath protecting the central nervous system, according to the…
