STING1 and neoplasm: A mouse model was implanted with tumors on one side and injected with irradiated cancer cells at the other side.62 Injection of irradiated cancer cells intensified the antitumor immune responses and reduced the contralateral tumor size when combined with an immune checkpoint inhibitor; this effect required STING expression in irradiated cancer cells.62 Moreover, direct radiation of implanted STING-deficient tumors did not provide an abscopal effect.
