IFN-γ production by peripheral blood NK cell subsets following exposure to IL-2, IL-12, and IL-15. Flow cytometric analysis of peripheral blood NK cells triggered by combinations of cytokines (IL-2 plus IL-12, IL-12 plus IL-15). GolgiPlug was added immediately at the time of stimulation until processed (0–16 h) or after 16 h with analysis of cells after 4 h (16–20 h). Data are representative of four experiments.
