CD274 and neoplasm: The antitumor effect (tumor free mice ratio was 20%) and the increase in infiltrated CD8+ T cells were also greater when AIMS(EPT, R848, PTX) was combined with αPD‐L1 than when it was combined with αPD‐1, suggesting that blocking PD‐L1 is better than blocking PD‐1 after AIMS(EPT, R848, PTX) treatment.
