Cell-mediated cytotoxicity potential of NK cells exposed to pI:C, DEP or pI:C+DEP. Results were assessed as percentage of killed target cells (K562 cancer cell line) and are expressed as fold induction over untreated NK cells. (A-E) Representative dot plots of all four conditions plus IL-12 stimulated NK cells as positive control to enhance cytotoxicity. (F) Summary of 5 individual experiments. Data are presented as mean±SEM. *significantly different from control, ^#significantly different between each other, *^,#p<0.05.
