In addition, there was also a positive correlation between the percentages of DNAM-1+Foxp3+ γδ T cells and Foxp3+ γδ Treg cells in the de novo AML and HI groups (P ≤ 0.001, r = 0.955, and P ≤ 0.001, r = 0.926, respectively) (Figure 2(d)). This evidence concerns the gene FOXP3 and acute myeloid leukemia.
