title: Treatment of PL/J mice with the superantigen, staphylococcal enterotoxin B, prevents development of experimental allergic encephalomyelitis.
abstract: Experimental allergic encephalomyelitis (EAE), an antigen induced autoimmune disease, is mediated by V beta 8+ CD4+ T cells in PL/J mice after injection with the autoantigen, myelin basic protein (MBP). Recently the superantigen, staphylococcal enterotoxin B (SEB), has been shown to peripherally anergize and delete T cells in a V beta specific manner. By treatment of PL/J mice with SEB, we have been able to protect PL/J mice from the development of EAE. Two-color FACS analysis of the spleens of SEB treated mice showed depletion of V beta 8+ CD4+ T cells. Consistent with this observation, spleen cells of SEB treated mice that did not show signs of EAE could not be stimulated in vitro with SEB but did respond to SEA. Thus, V beta specific superantigens may prove to be a preventative therapy for autoimmune diseases mediated by V beta specific T lymphocytes.
