IFNG and neoplasm: To delineate the mechanism underlying the observed accelerated tumor clearance in CD244fl/flLysMcre mice, we harvested tumor-infiltrating lymphocytes (TILs) from B16F10 tumor-bearing CD244fl/fl and CD244fl/flLysMcre mice and quantified IFN-γ expression in response to γ-irradiated B16F10 tumor targets ex vivo.
