Cytotoxicity assay of chromium-labeled YAC-1 target cells in the presence of peritoneal exudate cells recovered at day 4 after BDC T-cell transfer. Experimental mice received either an isotype control antibody or the anti-NK cell-depleting antibody treatment. A: Mice that received anti-asialo GM1 antibody treatment. B: Mice that received anti-NK1.1 antibody treatment. Effector/target ratios of 100:1, 75:1, 50:1, and 25:1 were incubated for 4 hours. Each point represents one experimental mouse.
