Stimulation with anti-PD-L1 antibody-treated DC enhances T cell cytotoxicity. Purified pmel T cells were stimulated in vitro for 5 days with gp100-pulsed DC pre-treated with NrIgG or anti-PD-L1 antibody. Cell cytotoxicity against gp100-coated EL4 target cells was measured in a 5 hour 51Cr release assay. *indicates p<0.01.
