Remyelination: what are the prospects for regenerative therapies in multiple sclerosis?

Abstract

Multiple sclerosis (MS) involves the immune system attacking the myelin sheaths surrounding axons and is a major cause of disability in working-age adults. Various approved therapies now provide reasonably good control over MS neuroinflammation, but none have a pronounced impact on the neurodegeneration associated with the disease. One prominent approach to fulfilling the unmet need for neuroprotective therapies, is the search for agents that promote remyelination , namely the generation of new oligodendrocytes that can form replacement myelin sheaths around denuded axons. In this article, I discuss some emerging targets for remyelinating therapies, mainly being pursued by recently formed small companies translating academic findings.
