Adult myelin-making cells display unique marker affecting activity

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…

Sugar molecule found to promote myelin repair in cell model

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…

Myelin may promote nerve cell damage in early immune attacks

Nerve cells coated with myelin ā€” the fatty substance that’s lost in multiple sclerosis (MS) ā€” 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…

Frequency moving to test agents with remyelination potential

Frequency TherapeuticsĀ announced that it is shifting its focus to advancing small molecules that aim to restore myelin, the protective cover around nerve fibers that is damaged and lost with multiple sclerosis (MS). This decision follows the failure of an investigative treatment for people with acquired hearing loss to…

Researchers Distinguish Remyelinated Brain Lesions Via MRI

An MRI technique called quantitative susceptibility mapping (QSM) can be used to accurately identify remyelinated brain lesions in people with multiple sclerosis (MS), a research team has discovered. Remyelinated lesions are those in which the myelin sheath ā€” the protective coating around nerve fibers that is progressively lost…

MS Focus of Paralyzed Veterans of America’s Newest Committee

Paralyzed Veterans of America (PVA) has formed a committee to better address the needs and interests of veterans with multiple sclerosis (MS), including help with obtaining care and disability benefits. The nonprofit PVA is the only congressionally chartered veterans organization working to assist and represent veterans with spinal…

Myelin Ceramides Altered in MS, Study Finds

Levels of myelin sheath components called ceramides are altered in the blood of people with multiple sclerosis (MS) and may be linked with retinal degeneration and physical disability, a study has found.Ā  Specific ceramides were altered only in those with progressive…

Myelin Regeneration Achieved in Mouse Model of MS

Therapies aimed at regenerating the myelin sheath can work to restore proper brain activity and may be a viable way of treatingĀ multiple sclerosis (MS), according toĀ researchers atĀ the University of California San Francisco. In the study, ā€œAccelerated Remyelination During Inflammatory Demyelination Prevents Axonal Loss And Improves Functional Recovery,ā€ published…

Instability of Myelin Membranes May Be True Trigger of MS, Study Reports

In multiple sclerosis (MS), scientists have long believed that the body’s own immune systemĀ attacked myelin sheaths,Ā the “insulating tape” that surrounds neurons, causingĀ the disease. But researchers at Tel Aviv University are challenging that view, inĀ a study reporting that MS may in fact be triggeredĀ byĀ an instability inherent in the myelin membranes. The…
