HLA-DRB5 and acute myeloid leukemia: Consistent with previous studies, the DC-like population derived from AML patients and healthy donors, expresses CD11c (ITGAX), CD18 (ITGB2), and MHC II molecules (HLA-DRB5, HLA-DRB1, and HLA-DRA) at high levels, but CD11b (ITGAM) at a low level (Fig. 2b), which identified the DC population [38].
