Fig. 2From: Overexpression of TLR2 and TLR9 on monocyte subsets of active rheumatoid arthritis patients contributes to enhance responsiveness to TLR agonistsToll-like receptor2 (TLR2) expression levels are increased in blood and synovial monocyte subsets of rheumatoid arthritis (RA) patients. a Flow cytometry analysis of TLR2 expression on blood monocyte subsets from healthy controls and RA patients. TLR2 expression for synovial monocyte subsets is also shown for RA patients. TLR2-positive cells appear in green (P1), blue (P2) or purple (P3). Gray histograms represent internal negative controls. Data are cell populations of representative donors. b TLR2 expression on each blood monocyte subset of healthy controls and RA patients is presented as mean fluorescence intensity (MFI) (meanâ±âstandard error of the mean (SEM)). Black bars healthy donors, gray bars RA patients. c TLR2 expression in the monocyte subsets from synovial fluids of RA patients is presented as MFI (meanâ±âSEM).
