This could be explained by a study done by Tan et al [15] who found a decreased tendency of exhausted T cells (PD1+CD244+, PD1+CD57+) in AML‐complete remission group and found a particular influence on CD8+ exhausted T‐cells, suggesting a poor anti‐leukemia immune response in these patients; however, in our study we did not measure expression of PD1 or exhaustion markers on BM lymphocytes at day 28 for further evaluations. This evidence concerns the gene CD8A and leukemia.
