In this scenario, the anti‐tumor response mediated by anti‐NKG2A pre‐coated NK cells + anti‐Qa1b was comparable to the efficacy results achieved by NK cells + anti‐NKG2A/Qa1b (Appendix Fig S5B and C); therefore suggesting the effect of anti‐NKG2A mAb is primarily exerted on the injected NK cells. This evidence concerns the gene KLRC1 and neoplasm.
