CD226 and acute myeloid leukemia: Similarly, an increased frequency of DNAM-1-Foxp3+ γδ T cells was observed in the AML-NR and de novo AML groups compared to the AML-CR and HI groups with the pattern AML-NR (median: 2.45%, range: 0.12%-26.00%) > de novo AML (median: 1.11%, range: 0.001%-7.41%) > AML-CR (median: 0.34%, range: 0.04%-2.37%) > HI (median: 0.15%, range: 0.001%-1.89%; NR vs. CR, P = 0.010; NR vs. HI, P = 0.001; de novo vs. HI, P ≤ 0.001) (Figures 2(a) and 2(b)).
