Immunosuppression of experimental allergic encephalomyelitis. III. In vitro evidence for induction of suppressor T lymphocytes in draining lymph node cells of animals immunized with myelin basic protein complexed to lipopolysaccharides.
J Immunol. 1982 May; 128(5):2073-80.JI

Abstract

We recently demonstrated that Lewis rats immunized with bacterial lipopolysaccharides (LPS) precomplexed to guinea pig myelin basic protein (BP) in complete Freund's adjuvant were less effective in inducing experimental allergic encephalomyelitis (EAE) than BP-immunized controls. When tested in vitro both lymph node cells (LNC) and spleen cells (SpC) of animals immunized with BP-LPS were less effective in proliferative responses to various mitogens, which included phytohemagglutinin, concanavalin A, purified protein derivative of tuberculin, LPS, and BP. Of importance immunization of rats with BP complexed to LPS results in the generation of cells in lymph nodes of these animals that suppress the mitogenic response of BP-immunized LNC and also SpC in mixed lymphocyte cultures. The suppressive effect of these cells in mixed lymphocyte culture reaction was found specifically in response to BP and to a lesser extent to LPS in LNC. SpC of BP-LPS immunized animals did not suppress the proliferative response to SpC of BP-immunized animals. Treatment of these LNC with antithymocyte serum and complement abolished this suppressive effect of LNC, suggesting that the immunoregulatory cells in LNC of BP-LPS immunized animals are suppressor T lymphocytes. The parallel between the in vitro induction of suppressor T lymphocytes in the draining LNC and the function of LPS in the development of EAE in Lewis rats suggests a possible immunologic significance of the effect.
