Interestingly, recent studies discussed the involvement of antibodies in the pathomechanism of MS [6], characterized by the occurrence of autoreactive antibodies against components of the myelin sheath, like myelin-basic protein (MBP) [7], myelin-oligodendroglycoprotein (MOG) [8], or proteolipid protein (PLP) [9]. This evidence concerns the gene MBP and myeloid sarcoma.
