oligodendrocyte progenitor cells

A specific epigenetic marker, or a chemical modification in DNA that alters gene activity, may explain why adult oligodendrocyte progenitor cells respond differently to therapies aiming to restore myelin than their neonatal counterparts, a study reports. The modification, called a lysine eight acetylation on histone H4, helps to regulate…

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,…

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…

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…

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…

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…

The formation of new myelin sheaths by oligodendrocytes is impaired in the absence of a small molecule, called Vav3, that oversees pathways regulating the shape of oligodendrocytes, new study reports. Its researchers pinpoint Vav3 as a potential therapeutic target to improve and speed myelin repair in diseases like multiple sclerosis…

Mature, adult oligodendrocytes can reacquire their ability to produce myelin to replace the ones lost in diseases like multiple sclerosis (MS) without undergoing a stem cell-like state, a new study shows. Myelin is the fat-rich substance that wraps around nerve fiber projections (axons) protecting them and increasing the speed of…

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 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 herpes virus that lies dormant in many people can hinder the repair of the neuron-protecting myelin sheath whose deterioration causes multiple sclerosis, a study reports. The finding about the HHV-6 virus may help explain differences in the symptoms and progression of the disease from person to person, researchers said.

RegeneRx Biopharmaceuticals, Inc., announced the publication of a research article detailing the process by which Thymosin beta 4 (Tβ4), the company’s novel therapeutic peptide, effectively promoted the remyelination process in two separate animal models commonly used for multiple sclerosis (MS) research. The article, “Thymosin beta4 promotes oligodendrogenesis in the demyelinating…

A study from the University of Cambridge showed that the membrane-bound signaling protein EphrinB3, which acts by inhibiting the maturation of oligodendrocytes, also blocks the remyelination of damaged neurons in multiple sclerosis (MS). The study, “Antibody-mediated neutralization of myelin-associated EphrinB3 accelerates CNS re-myelination,“ uncovered a new target to explore…
