Summary: Researchers have discovered a two-pronged approach to restore myelin on regenerated axons in a mouse model of optic nerve damage. The findings have positive implications for the treatment of multiple sclerosis.

Loss of myelin—the fatty substance that surrounds the axons of nerve cells—is one of the reasons nerve cells fail to recover after injury and in some diseases. Myelin acts like insulation, covering the long axon threads that enable high-speed communication between neurons. Without myelin, the neurons may not be able to coordinate well, leading to less than optimal function.
