Monocyte subsets and expression of phenotypic markers on spondyloarthritis (SpA) and rheumatoid arthritis (RA) patients and healthy donor monocytes. The percentage of CD14⁺CD16^-, CD14⁺CD16⁺, and CD14^dimCD16⁺ monocytes from SpA and RA patients and healthy donors was measured with flow cytometry (A). Expression of CD64, CD200R, and CD16 on monocytes from SpA and RA patients and healthy donors was measured with flow cytometry and expressed as geometric mean fluorescence intensity (gMFI). Data are represented as median and interquartile range of at least seven independent experiments (B).
