TIGIT and nasopharyngeal carcinoma: Five subsets were obtained by downscaling the NK cells of GSE150825(nk1-5, Fig. 3I), and compared to the NLH group, higher expression of ZNF683, TIGIT, and LAG3 could be observed in the nk3 cell subset (Fig. 3J) in the NK-NPC group, which is consistent with our previous results.
