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 study published online March 27 in Developmental Cell, researchers at Cincinnati Children’s Hospital Medical Center report that treatment with a microRNA called miR-219 restarted production of a substance called myelin in nerves of the central nervous system. Myelin forms a protective sheath around nerves, allowing them to efficiently transmit electrical impulses that stimulate movement.
