Microrna treatment restores nerve insulation, limb function in mice with MS

Scientists partially re-insulated ravaged nerves in mouse models of multiple sclerosis (MS) and restored limb mobility by treating the animals with a small non-coding RNA called a microRNA. In a new article, researchers report that treatment with a microRNA called miR-219 restarted production of a substance called myelin that is critical to normal function of the central nervous system.
