Monitoring neutrophil activation in juvenile rheumatoid arthritis by S100A12 serum concentrations

Abstract

S100A12 serum concentrations indicate neutrophil activation in JRA and correlate with disease activity. S100A12 may indicate synovial inflammation even when other signs of arthritis are absent. Its function as a proinflammatory factor secreted by activated neutrophils makes this protein a potential target for future therapies.
