Figure 5.
Functional properties of purified subsets after IL-15-stimulation. The purified subsets were labeled with CFSE and stimulated with IL-15 (10 ng/mL). After 7 days the cells were restimulated with PMA/ionomycine and brefeldin A and stained intracellular for indicated cytokines followed by FACS analysis (gamma-1 [g-1] used as control mAbs). (A) CD8+ T cells purified from UCB. (B) Peripheral naive CD8+ T cells. (C) Cytotoxic CD8+ T cells (CD27-CD45RAbright). (D) Noncytotoxic CD8+ T cells (CD27+CD45RAdull/neg). Data are one representative experiment of 4 performed.
