We further investigated the potential distinct features between the IFNγ− versus IFNγ+ subgroups of CRC in terms of TIL density and secreted cytokines, as well as immunomodulatory factors such as PD1, IL-10, and Transforming Growth Factor beta 1 (TGFβ1), known to suppress the IFNγ response. The gene discussed is IL10; the disease is colorectal carcinoma.
