In this disorder, your immune system attacks the myelin sheath or the cells that produce and maintain it. This attack causes inflammation and injury to the nerve sheath and ultimately to the nerve fibers that it surrounds.

WebOct 24, 2016 · MBP is a major component of both PNS and CNS myelin. Finally, proteolipid protein (PLP), which has four membrane-spanning segments, is a major component of CNS myelin. In the adult, these myelin proteins exhibit very little turnover, indicating that the mature myelin sheath is normally quite stable. WebJun 22, 2015 · Myelinated nerve fibers have evolved to enable fast and efficient transduction of electrical signals in the nervous system.
