IL-4 and IFN-gamma each have potent effects on B cell responses as well as strong mutual antagonism. Here we have examined the quantitative effects of these cytokines on CD40 ligand-induced B cell proliferation, cell survival, and division-linked isotype switching. Both IL-4 (strongly) and IFN-gamma (weakly) enhanced the number of B cells found in culture by reducing the average time cells take to enter the first division cycle and by promoting B cell survival. When added in combination, the… CONTINUE READING
