in view of the role that lymphoid activity plays in resistance of the host to disease and the recent demonstration that interleukin ii ( il-2 ) has a profound effect on regulation of immune function both in vitro by activation of cytolytic cells and in vivo by augmenting lymphoid cell activity , studies to evaluate possible morphological changes in differentiation , proliferation and distribution in lymphoid organs after in vivo administration of il-2 were performed in conjunction with evaluation of cellular immune response modification using a functional cytolytic assay .
