the suppressor cells inhibited the efferent limb of the dth response because ( 1 ) hyporesponsive recipients of tdsf-treated spleen cells had splenic effector t cells capable of transferring dth to dncb into naive secondary recipients and ( 2 ) the ability of lyt 1+,2- effector tdth cells to transfer a secondary dth response to dncb was inhibited by co-incubation with macrophages or lyt 1-,2+ t cells treated with tdsf .
