CD226 and acute myeloid leukemia: The results demonstrated that Foxp3+ γδ, TIGIT, and DNAM-1 on Foxp3+ γδ cell subsets were evidently decreased in AML patients who achieved CR (Foxp3+ γδ: P = 0.039; TIGIT+Foxp3+ γδ: P = 0.008; DNAM-1+Foxp3+ γδ T cells: P = 0.039), which may be due to the elimination of blasts.
