    Abstract:
    In vivo administration of anti-CD4 mAb (GK1.5) has been shown to be effective in preventing acute and relapsing experimental allergic encephalomyelitis (EAE). In the present report we have studied the depletion of CD4+ cells by a single dose of GK1.5 on the immune response to myelin basic protein and in the development of EAE. Our studies show that depletion of CD4 cells in mice that had received encephalitogenic CD4+ T cells altered the kinetics of acute and relapsing EAE, but did not prevent disease altogether. The in vitro T cell proliferative response to myelin basic protein in lymph node cells was maintained in the presence of significant depletion of CD4+ cells. These studies indicate that the population of Ag-reactive cells to be large and relatively refractory to antibody therapy. The implication of these results to therapy of human autoimmune disease is discussed.
