The CD14+HLA-DRlow/− MDSCs are upregulated in CLL patients. (A) Representative HLA-DR expression in CD14+ monocyte population of the control group, MBL patients and CLL patients. (B) Frequency of CD14+HLA-DRlow/− MDSCs in CD14+ monocytes of CLL patients (42.1±14.5%; n=49) were significantly elevated compared with MBL (24.95±8.1%; n=23) and control (6.1±2.2%; n=21) patients (both were P<0.0001). (C) Frequency of CD14+HLA-DRlow/− MDSCs in CD14+ monocytes were significantly increased in advanced stages compared with the stage I CLL patients (stage II: n=18; P<0.0001; stage III: n=12; P<0.0001; stage IV: n=7; P=0.0005). ***P<0.001. CD14, cluster of differentiation 14; HLA, human leukocyte antigen; MDSCs, myeloid-derived suppressor cells; CLL, chronic lymphocytic leukemia; MBL, monoclonal B cell lymphocytosis.
