IFN-γ production by tumor-infiltrating lymphocytes. TIL were isolated from tumors of mice vaccinated with (R)-DOTAP/E7 or (S)-DOTAP/E7 and pulsed for 6 h with E7 or an irrelevant peptide (NP). a Percentages are IFN-γ⁺CD8⁺ cells out of all CD8⁺ cells. One dot plot is shown for each group that is representative of three experiments. b IFN-γ⁺-producing cells per 10,000 CD8⁺ cells, P < 0.05. n = 6–7
