CD8A and neoplasm: Moreover, in mice bearing B16/F1 tumor grafts, although the expression of IL-2Rβγ in tumor-infiltrated CD8+ T (MFI 208–250) and NK cells (MFI 291–430) was comparable to that of IL-2Rβγ in peripheral CD8+ T (MFI 172–223) and NK cells (MFI 240–373) (Figure S3(C)), the levels of NKG2A in tumor-infiltrated CD8+ T (MFI 947–1352) and NK cells (MFI 899–2036) were also significantly higher than those of NKG2A in peripheral blood CD8+ T (MFI 83–376) and NK cells (MFI 377–459) (Figure S3(B,C)).
