IFNG and neoplasm: To ascertain whether the mice that experienced complete tumor regression with mch1N11 and anti-PD-1 treatment and were subsequently resistant to E0771 rechallenge (Fig. 4a) had an enhanced tumor-specific immune response, we evaluated IFNγ production in splenocytes cultured with and without irradiated E0771 cells by EliSpot (Fig. 4b).
