MBP and experimental autoimmune encephalomyelitis: For instance, when mice (strains PL/J and SJL/J) were infected with a vaccinia virus (VV) encoding for the first 23 immunodominant amino acids of myelin base protein (MBP), these mice did not develop experimental autoimmune encephalomyelitis (EAE) and were protected from the subsequent induction of EAE via MBP peptide immunization [77].
