However, further analysis demonstrated that the levels of both NKG2A (Figure 2(B)) and IL-2Rβγ (Figure 2(C)) in tumor-infiltrated CD8+ T (MFI 1108–2560) and NK cells (MFI 1331–2484) were significantly higher than those of NKG2A and IL-2Rβγ in peripheral CD8+ T (MFI 124–230) and NK cells (MFI 222–244) derived from mice bearing MC38 tumor grafts. Here, KLRC1 is linked to neoplasm.
