XPE-induction of caspase-3 activating CD8 cells. CD8 T cells were isolated from spleens of experimental and control mice on day 8 after immunization with XPE and mixed at the indicated ratios with the indicated target cells. Caspase-3 activation was quantified as percentage of target cells positive for anti-activated caspase-3 antibody staining by flow cytometry. The results are representative of 3 independently performed experiments.
