Multiple sclerosis seems to be less severe in people with higher levels of the minor adult hemoglobin variant A2 (HbA2) in their blood, according to a team of Turkish researchers. This could be due to this variant having a higher protective effect on the red blood cell membrane. The authors speculate that HbA2 could therefore be playing a role in reducing long-term neural injury in MS.

Oligodendrocytes — brain cells that wrap themselves around neurons to produce myelin — are much more diverse than previously believed. Scientists in Sweden, using a new type of sequencing, have discovered more than a dozen different kinds, including an oligodendrocyte subtype involved in motor learning, a finding that might spur new research into protecting…

Regions of DNA called super-enhancers regulate immune cell activity, including the body’s response to threats like inflammation or pathogens, and now scientists have found that they also harbor genetic variants associated with autoimmune diseases — gene variants that may be the “master switches” for these conditions. The findings were described in the study “…

Researchers at the University of Buffalo’s Hunter James Kelly Research Institute (HJKRI) discovered that the cells that form myelin in the nervous system respond to mechanical stimulation by activating molecules from a specific pathway, which are transferred to the nucleus, triggering myelination. The findings, which may be key to developing new therapies…

A substance called fluorosamine was seen to boost remyelination in mice by preventing the synthesis of chondroitin sulfate proteoglycans and by promoting oligodendrocyte function. The findings showed that targeting molecules that block remyelination may be a promising therapeutic approach in multiple sclerosis (MS). Upregulation of chondroitin sulfate proteoglycans — large molecules…
