PDCD1 and acute myeloid leukemia: The analysis of NKT-like cells showed no statistically significant differences in the expression of LAG-3 (51.02 ± 17.17 in AML and 57.01 ± 13.66 in healthy donors) (Fig. 2a), a lower percentage of cells expressing TIM-3 in AML patients (56.85 ± 13.83) compared with healthy donors (62.85 ± 9.44) (Fig. 2b) and no differences in the expression of PD-1 (11.79 ± 15.69 in AML and 9.21 ± 20.29 in healthy donors) (Fig. 2c).
