Kinetics of anti-CD4-induced T helper cell depletion and inhibition of function. Activation of T cells by the CD3 pathway inhibits anti-CD4-mediated T cell elimination and down-regulation of cell surface CD4.

In vivo treatment with anti-CD4 antibody profoundly suppresses a number of T cell-dependent responses and is clinically useful in the treatment of certain mouse models of autoimmune disease. Treatment with anti-CD4 antibody will inactivate and can deplete CD4 T cells, but the mechanisms responsible for these effects are incompletely understood. When mouse… CONTINUE READING
