Abstract
Spleen cells from mice injected i.v. with large doses of BCG respond to PHA [phytohemagglutinin] stimulation less intensely than do normal spleen cells. Nylon wool column purified BCG treated T [thymus-derived] cells also had a low PHA reactivity. Unfractionated spleen cells, adherent cells or T-enriched populations from BCG treated mice, when added to normal T cells, lowered their PHA reactivity. When the same BCG treated cell populations were added to tumor cells in vitro, they inhibited their growth.
