Omega-3 Transporter Crucial for Myelin Production in MS.
A protein called Mfsd2a, which transports molecules that contain omega-3 fatty acids, is essential for regulating cells that make the fatty coating on nerve fibers, or myelin sheath, that’s damaged in multiple sclerosis (MS), a study indicates. In mice lacking Mfsd2a, the cells that make myelin, or oligodendrocytes, fail to mature, leading to a decline in cellular levels of omega-3 fatty acids and a reduction in myelination. The study opens up potential avenues to develop therapies and dietary supplements based on omega-3 that might help retain myelin in the aging brain and possibly to treat patients with neurological disorders stemming from reduced myelination.
