this report shows that , in contrast to the lack of increased activity observed after specific stimulation with lymphoma cells , nonspecific stimulation of long-term mltc cells either with supernatants from secondary mixed leukocyte cultures ( 2 degrees mlc sn ) or with supernatants from concanavalin a-stimulated spleen cells leads , on a per cell basis , to a further 5 to 10-fold increase in ctl activity .
