Researchers at the Oregon Health & Science University have discovered a plant-derived small molecule that can promote the growth of cells that produce myelin, the protective coating around nerve fibers that’s damaged in multiple sclerosis (MS). The naturally occurring molecule, sulfuretin, blocks the activity of an enzyme that…
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…
A PhD student at the UMass Chan Medical School will use funding from a newly awarded fellowship to advance his research into the mechanisms used by cells to repair myelin, the protective sheath around nerve cells that’s damaged in multiple sclerosis (MS) and other demyelinating conditions. The ongoing…
Progentos Therapeutics said it received $65 million in funding to support the development of myelin regeneration medications able to restore function in people with multiple sclerosis (MS) and other diseases marked by myelin loss. The biotech company said it will use the funds to advance its MS program…
A small molecule called ESI1 stimulated the repair of the myelin sheath, the fatty coating on nerve fibers that is damaged in multiple sclerosis (MS), a study found. In an MS mouse model, this resulted in improved motor function and nerve cell communication, as well as reduced signs…
Scientists have developed a technique to more precisely map the myelin sheath, the fatty covering around nerve fibers that is damaged in multiple sclerosis (MS), in people undergoing an imaging scan. While further work is needed, its use “produced promising initial results,” the scientists wrote, noting that this…
Myrobalan Therapeutics has secured $24 million in series A financing to support the development of oral medications for multiple sclerosis (MS) and other diseases of the central nervous system (CNS), which comprises the brain and spinal cord. The company’s pipeline currently includes three candidate therapies…
The presence of damaged myelin — the fatty, protective substance surrounding nerve cells that’s lost in multiple sclerosis (MS) — may be more harmful to nerve cells than its removal altogether, according to new preclinical research. In mouse models of myelin-associated disease, a failure of microglia — the…
A protein called Daam2 helps to regulate the activity of cells in the brain that make myelin, the fatty covering around nerve fibers that’s damaged in multiple sclerosis (MS), a new study shows. By uncovering how that protein functions in the brain to boost myelin repair, researchers have discovered…
Treatment with polysialic acid, a sugar molecule naturally made in the body, may be a promising approach to boost myelin repair in people with multiple sclerosis (MS), according to a new study in lab-grown brain samples. Findings show that the molecule increased myelin repair, or remyelination, in the cell…
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…
A detailed examination of nerve tissue isolated from multiple sclerosis (MS) patients showed changes to the myelin sheath before the appearance of substantial inflammatory activity and lesions, a study reported.
