Combinatory effect of HLA-B-21 dimorphism and NKG2A gene variants on granzyme B levels and clinical outcome of IL-2 based therapy in AML patients. (A–D) Impact of NKG2A SNP alleles on granzyme-B load of CD16+ CD56dim NK cells in AML patients at the beginning and after one course of IL-2 based therapy in HLA-B-21 TT carriers (A, B) and HLA-B-21 M/x carriers (C, D). (E) Leukemia-free survival for patients with NKG2A GG (n=11) or C/x (n=31) in patients with an HLA-B –21 TT genotype. (F) Leukemia-free survival for HLA-B –21 M/x patients dichotomized into NKG2A GG (n=16) and C/x (n=21). AML, acute myeloid leukemia; LFS, leukemia-free survival; NK, natural killer.
