KLRC1 and neoplasm: Notably, as shown in Figure S2, NKG2A+IL2Rβγ+CD8+ T cells and NKG2A+IL2Rβγ+ NK cells accounted for 56–73.9% and 18.9–32.8% of NKG2A- and/or IL-2Rβγ-expressing tumor-infiltrated immune cells, indicating that NKG2A and IL2Rβγ were predominantly co-expressed in tumor-infiltrated CD8+ T and NK cells.
