RIGI and neoplasm: Irradiated SMMC-7721 CRIG-Ish tumor TIDCs less strongly stimulated proliferation of allogeneic T cells than did irradiated SMMC-7721 NCsh tumor TIDCs, indicating RIG-I deficiency-induced immune tolerance, although both TIDCs induced lower MLR than did irradiated splenic DCs (Fig. 5f, n = 6).
