three immunological functions were examined : the production of lymphokine ( s ) ( lk ) by t-lymphocytes , the proliferative response of spleen cells to parasite spore fragments , and the ability of splenic and thioglycollate-induced peritoneal macrophages to act as accessory cells in antigen-induced t-cell proliferation .
