A synthetic peptide corresponding to residues 87-99 (S87-99) of myelin basic protein (BP) induced the proliferation of an encephalitogenic, BP-specific T cell line selected in vitro from inbred Buffalo-strain rats (RT1b). Active immunization with guinea pig (GP)-BP or S87-99 in complete Freund's adjuvant (CFA) and intraverous pertussigen induced acute experimental autoimmune encephalomyelitis (EAE) 10-12 days after immunization. Fifty percent of recovered rats developed a single relapse 17-21 days after immunization. T lymphocytes selected in vitro with S87-99 transferred acute, non-relapsing EAE into naive recipients. Histological examination during acute EAE revealed foci of inflammatory cells associated with demyelination in the spinal cords and peripheral nerve roots. Thus, as in several other rodent strains, the 87-99 region of BP is antigenic and encephalitogenic in the inbred Buffalo-strain rat. Additionally, the 87-99 sequence of GP-BP was predicted to be antigenic by two different methods. These suggest that the 87-99 region of BP, which is highly conserved among mammalian species, may be widely encephalitogenic due to antigenic-intrinsic properties.
