This study is aimed at characterizing whether the TIGIT/DNAM-1 axis is involved in the distribution and expression of Foxp3+ γδ Treg cell subsets in acute myeloid leukemia (AML) patients of different clinical statuses: de novo AML (27 patients), AML in nonremission (NR) (7 patients), and AML in complete remission (CR) (12 patients). Here, TIGIT is linked to acute myeloid leukemia.
