Fig. 4From: TNFα expressed on the surface of microparticles modulates endothelial cell fate in rheumatoid arthritisSurface expression of TNFα after incubation of rheumatoid arthritis (RA)-microparticles (MPs) with etanercept (ETA). Percentage of surface (s)TNFa expression on RA-MPs is shown after in vitro incubation with ETA at different concentrations for 2 h. Values are expressed as means ± SD; *p < 0.05Back to article page
