WebRemyelination is the natural repair mechanism of demyelination, and it is proposed that remyelination protects against progressive axonal injury and consequently also diminishes long-term disability in multiple sclerosis (MS) patients. It is thought that remyelination recapitulates many steps also occurring during physiologic myelin development. WebIn some cases, such as recovery of vision following demyelination of all axons within the optic nerve (5,6), the routing of information along unmyelinated axons or axons that escaped demyelination could not have contributed to functional recovery.
