Blocking a death receptor causes damaged myelin, the protective coating surrounding nerve cells, to repair itself, according to a study published Sunday (July 3) in Nature Medicine. The finding suggests that drugs targeting the receptor could help treat multiple sclerosis by reversing the myelin damage characteristic of the disease.
“Showing remyelination, as they do in vivo and in vitro, is a pretty cool result,” said Richard Ransohoff, a Cleveland Clinic neuroscientist who was not involved in the work. The new receptor is a novel first step in potentially repairing damaged nerves of multiple sclerosis patients, he said.
Current multiple sclerosis drugs slow the disease’s progression by quieting the inflammatory response of the immune system, which attacks the myelin surrounding nerve cells and kills oligodendrocytes, brain ...
