CD8+ T cells induced with IL-15 showed better responsiveness to exogenous IL-15. (a) Positively purified CD8+ T cells from each group of animals were labeled with CFSE and then cultured for 3 days in the medium containing IL-2 or IL-15. Proliferation was measured by gating on anti-CD8α and P18-I10–H-2Dd tetramer-positive cells. (b) P18-I10-specific CD8+ T cells were purified by sorting anti-CD8α and P18-I10–H-2Dd tetramer-positive cells. Cells were cultured and proliferation was measured by determining [3H]thymidine uptake.
