The only cellular receptor for rubella virus identified to date is the myelin oligodendrocyte glycoprotein (MOG), an adhesion molecule that is important in nerve myelination and is implicated as a target antigen in the pathogenesis of several autoimmune demyelinating diseases (including multiple sclerosis/MS), and in the central nervous system (CNS) damage in congenital rubella syndrome [11]. The gene discussed is MOG; the disease is myeloid sarcoma.
