The differentiation of CD4+ T cells into a Th1 vs Th2 phenotype profoundly influences the outcome of autoimmune and infectious diseases. B7 costimulation has been shown to affect the production of both Th1 and Th2 cytokines, depending on the system studied. There is, consequently, great interest in manipulating the B7 costimulatory signal for therapeutic purposes. To optimally manipulate this key immunoregulatory pathway, the contribution of B7 costimulation to cytokine production requires… CONTINUE READING
