In this study, only one case had an FLT3-ITD mutation out of 11 AML cases, and we found a similar trend with a high percentage of Tim-3 + CD3+/CD4+/CD8+/CD244+/CD57+ and PD-1 + Tim-3 + CD4+ T cells in the BM, while, unlike the reported results, there was no apparent difference in PB compared with the other AML samples. The gene discussed is CD4; the disease is acute myeloid leukemia.
