L1- NK-CD56bright: high expression of inhibitory receptor genes NKG2A, TIGIT, TIM3, and CD96L2- NK-CD56dim: high expression of inhibitory receptor genes TIM3 and CD96L5- LrNK-XCL1: high expression of inhibitory receptor genes KLRC1 and TIGIT;overexpression of common tumor-associated genes RHOB, TALDO1, HLA-DPA1, and TKT. Here, TIGIT is linked to neoplasm.
