Alexander Gow, PhD, a professor at Wayne State University School of Medicine in Detroit, has been awarded a grant to study how stressed oligodendrocytes, the cells that produce myelin in the brain and spinal cord, could be at the origin of multiple sclerosis (MS). The three-year, $644,827 grant from…

Junctions between nerve cells and certain cells called oligodendrocyte precursor cells, or OPCs, in the brain and spinal cord may play an important role in producing myelin, the protective substance that’s progressively lost in multiple sclerosis (MS), new research suggests. OPCs are abundant in the brain and spinal…

The company’s pipeline currently includes three candidate therapies…
Blocking the activity of a protein complex called the NLRP3 inflammasome lessened disease severity in a mouse model of multiple sclerosis (MS), a study reports. Results point to NLRP3 as a promising target to ease inflammation in people with MS, but additional studies will be needed to determine the…
Nerve cells coated with myelin — the fatty substance that’s lost in multiple sclerosis (MS) — may be more vulnerable to degeneration in an inflammatory environment than cells lacking myelin, researchers working in MS patient tissues and mouse models report. The scientists believe the phenomenon arises when certain…
Using stem cells derived from people with multiple sclerosis (MS), researchers developed cerebral organoids, or “mini-brains,” to better study the cellular and molecular mechanisms leading to the neurodegenerative disorder. Initial analysis showed that patient-derived stem cells, especially those from people with primary progressive MS (PPMS), tend to be…
Frequency Therapeutics has established a clinical advisory board, with experts across neuroscience fields, to help guide its small molecule treatment candidate for remyelination in multiple sclerosis (MS) into clinical testing. The company is planning to initiate a first trial of the molecule, designed to boost remyelination — the…
Baclofen, an approved therapy for spasticity in multiple sclerosis (MS) patients, promoted the repair of myelin — the protective sheath around nerve fibers that’s progressively lost in MS — in a mouse model of the disease, a study showed. These findings suggest baclofen — sold as oral tablets,…
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…
Immune system reaction to casein, a protein in cow’s milk, can trigger an inflammatory neurological disease in mice that’s similar to multiple sclerosis (MS) and includes the loss of myelin, a study reported. “These results identify how consumption of milk and milk products may exacerbate the autoimmune response in…

In an unexpected discovery, scientists working to understand the biological underpinnings of brain tumors found that increasing the activity of a protein receptor called PDGFRA reduces the production of myelin — the fatty coating that is lost in multiple sclerosis (MS) — in the nervous system. “We saw that…
Pro-inflammatory T helper 17 cells, known as Th17 cells — a type of immune cell known to play a role in multiple sclerosis (MS) — directly interact with myelin-producing cells, promoting their damage and death, according to a study in a mouse model of MS and in samples from…
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 signaling protein called fractalkine helps to regulate the development of oligodendrocytes, cells of the nervous system responsible for making myelin — the protecting coating of nerve cell fibers that is damaged and lost in multiple sclerosis (MS). This finding was in the study, “Fractalkine signaling regulates…
The enzyme TET1, which is progressively lost with age, is essential to activate genes needed to repair myelin — the sheath around nerve cells that is damaged in people with multiple sclerosis (MS) — a study in mice has found. The…
A new 3D model of the human nervous system is meant to mimic key processes in the development of the myelin sheath — the fatty coating around nerve cells that is damaged in multiple sclerosis (MS) — to help with research into treatments that promote myelination. This model might also…
A gene called Mertk has important roles in the repair of myelin, the fatty substance that surrounds and protects neurons and that is lost in multiple sclerosis (MS). The findings were published in Cell Press, in the study “Multiple sclerosis risk gene Mertk is required for…
Prolonging a cellular defense mechanism shown to restore myelin — the protective sheath around nerve cell fibers that is lost in multiple sclerosis (MS) — may be key to treating the neurodegenerative disease, a study in MS mouse models suggests. That defense mechanism, called integrated stress response (ISR), helps…
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…
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,…
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’…
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,…
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,…
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…
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).
