Abstract

Experimental allergic encephalomyelitis (EAE) is a model for the in vitro and in vivo study of T-cell activation. It is an autoimmune disease mediated by T lymphocytes of the helper T-cell (Th) subset. After sensitization to guinea-pig myelin basic protein in complete Freund's adjuvant, Lewis rats develop an autoimmune response to central nervous system (CNS) myelin basic protein, manifested clinically as paralysis and histologically by a perivascular mononuclear cell infiltrate of the CNS parenchyma. Suppressor cell regulation of EAE has long been suspected because Lewis rats, which spontaneously recover from active disease, are resistant to reinduction of active EAE, even though effector T-cell lines can be rescued from these recovered rats. Using cyclosporin A, an immunosuppressive agent believed to inhibit Th cell function, suppressor T-cell (Ts) lines have now been generated from recovered Lewis rats. These Ts cells, when admixed with guinea pig myelin basic protein-specific Th cells, will prevent the adoptive transfer of EAE. The Ts cells appear to be CD4+, which explains previous observations that CD8+ lymphocytes are not important in the recovery of EAE in the rat. This is the first direct demonstration of Ts-cell regulation of EAE.
