We then demonstrated that IFNGR knockout had no impact on cell proliferation (Figure 5D), whereas cell death (7‐Aminoactinomycin D [7‐AAD] positive) of MB49IFNGR‐KO was reduced when cocultured with tumour‐specific T cells from post‐cryoablation mice (Figure 5E). The gene discussed is IFNGR1; the disease is neoplasm.
