Increased ex vivo NK cytotoxicity in CD69−/− mice. Mice received 104 RMA-S (A) or RM-1 cells (B) intraperitoneally 72 h after inoculation, total unfractionated peritoneal cells (A and B) from CD69−/− and WT mice were analyzed for cytotoxicity against YAC target cells. Two animals were used per experimental group (mean ± SE). (C and D) Purified NK cells were used, untreated or treated with IL-2, respectively. (D) Two animals were used per experimental group (mean ± SE). Open symbols, WT; closed symbols, CD69−/−. The results are representative of three similar experiments.
