Levels of monocyte subsets in blood and synovial fluids from rheumatoid arthritis (RA) patients. a Flow cytometry analysis of CD14++ CD16− (P1), CD14+ CD16+ (P2) and CD14low CD16++ (P3) blood monocytes from healthy controls and RA patients and of synovial monocytes from RA patients. Data are cell populations of representative donors. b Percentage of blood monocyte subsets from healthy controls and RA patients. Black bars healthy donors, gray bars RA patients. c Percentage of monocyte subsets from synovial fluid of RA patients. Data represent the mean ± standard error of the mean. Striped bars RA patient synovial fluids (SF): *p ≤0.05 and ***p ≤0.001
