A thyroid hormone-mimicking compound not only prevented nerve cell damage but promoted the cells’ survival in a mouse model of multiple sclerosis (MS). This discovery advances previous research showing that the compound, called sobetirome, can induce the repair of myelin, the protective sheath around nerves. The data suggest…

New research in mice suggests that poor recycling of cholesterol in the brain impairs the repair of myelin, the protective coat surrounding nerve cells that is lost in multiple sclerosis (MS). Pharmacological stimulation of cholesterol synthesis by brain immune cells — called microglia — boosted the regeneration of myelin,…

The pro-inflammatory environment characteristic of multiple sclerosis (MS) reduces the levels of PPAR-gamma — a receptor protein whose activation dampens inflammation — and impairs myelin processing in immune cells that clear myelin debris, a study suggests. These findings may help to better understand how PPAR-gamma regulates the function of these…

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…

Scientists have created myelin-producing cells, called oligodendrocytes, from pluripotent stem cells derived from patients with multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS) in just three weeks. They also demonstrated these lab-made oligodendrocytes were able to produce myelin — the fatty substance that normally wraps around neurons’…

Start2Cure Foundation is funding a research project that will investigate the potential of a gene therapy approach to treat multiple sclerosis (MS).

Extracellular vesicles (EVs), tiny sacs released from myelin-producing cells called oligodendrocytes, may help dampen the immune system’s attack against myelin, whose loss is the hallmark of multiple sclerosis (MS), a new mouse study shows. The findings suggest that oligodendrocytes-released EVs could work as an universal immunotherapy for MS…

There may be a better way of repairing the insulation surrounding damaged neurons that could lead to new treatments for multiple sclerosis (MS), a study suggests. The data showed that blocking the protein sphingomyelin hydrolase neutral sphingomyelinase 2, or nSMase2, could improve the quality of the myelin surrounding…

Suppressing pyruvate kinase M2 (PKM2) — an enzyme involved in cellular metabolism — in T-helper (Th) immune cells lessened myelin loss and disease severity in a mouse model of multiple sclerosis (MS). Myelin, the protective sheath around nerve fibers that helps speed transmission of signals between nerve cells, is damaged and lost…

The anti-inflammatory medication VX-765, which is delivered through the nose (intranasal), was found to limit disease progression in a preclinical model of multiple sclerosis (MS) by blocking a protein called caspase-1. The medication helped prevent damage to brain cells in mice. Researchers from the University of…

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…

A pathway controlled by three proteins — Daam2, Nedd4, and VHL — was identified by researchers as a key regulator of myelin production during central nervous system development and regeneration after injury. Myelin, the protective fatty layer that covers nerve fibers and helps to speed transmission of signals between nerve cells,…

Dutch Amarna Therapeutics announced a research collaboration with Spanish Progreso y Salud Foundation (FPS) to investigate the efficacy of its gene therapy delivery technology in multiple sclerosis (MS) and diabetes. MS is thought to be caused by immune-mediated inflammation that damages myelin — an insulating sheath around nerve…

Remyelination — or the restoration of lost myelin, the protective sheath surrounding nerve cell fibers — in multiple sclerosis (MS) depends mainly on pre-existing oligodendrocytes (myelin-producing cells), rather than on newly-generated oligodendrocytes, according to a recent study. The data also showed that perineuronal, or satellite,…

Before signs of neurodegeneration in the brain and spinal cord are evident in mice with experimental autoimmune encephalomyelitis (EAE) — which resembles human multiple sclerosis (MS) — signs can first be found in the network of nerves innervating the gastrointestinal (GI) tract, a study reports. Additional research is needed…

Tolebrutinib (SAR442168), an investigational oral BTK inhibitor to treat relapsing forms of multiple sclerosis (MS), was seen to prevent the loss of myelin when given to a mouse model of demyelination in a preclinical study. The investigative therapy achieves this by preventing…

Immune B-cells are more abundant and have a pro-inflammatory profile in the cerebrospinal fluid (CSF), the fluid that bathes the central nervous system,  compared to blood in people with relapsing-remitting multiple sclerosis (RRMS), a study reports. The results suggest that therapeutic strategies targeting the CSF B-cells could constitute a…

Two specific bacteria present together in the gut led to more immune attacks on myelin and harsher symptoms in a mouse model of multiple sclerosis (MS). These findings add to existing evidence supporting the link between gut microbiota and MS, and highlight the need to consider potential combined effects of these…

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…
