IFNG and neoplasm: We also measured the IFNγ production of the tumor‐infiltrating lymphocytes (TILs) isolated from the EG7 or B16 tumors with I3A or vehicle treatment via IFNγ ELISpot assay, and the result showed that I3A treatment boosted IFNγ production level in the TILs of both tumor models (Figure 4D,E).
