We also found that the expression of TIGIT, LAG3 and ZNF683 was mainly concentrated in the NK-NPC group rather than the NLH group by mapping the expression of NKG7, TIGIT, LAG3, HAVCR2 and ZNF683 to the tSNE results of the nk1-5 cell subsets (Fig. 3K). This evidence concerns the gene HAVCR2 and nasopharyngeal carcinoma.
