Interestingly, very few CD8+ T cells were present in TRAMP-C2 tumor tissue suggesting that endogenous STING activity in TRAMP-C2 tumors is not sufficient to attract T cells possibly due to an immunosuppressive microenvironment in TRAMP-C2 tumors, which prevents infiltration of T cells36, 37. This evidence concerns the gene STING1 and neoplasm.
