Figure 1From: Potential role and mechanism of IFN-gamma inducible protein-10 on receptor activator of nuclear factor kappa-B ligand (RANKL) expression in rheumatoid arthritisComparison of CXCL10 concentrations between patients with rheumatoid arthritis (RA) and those with osteoarthritis (OA). CXCL10 concentrations of synovial fluid (a) and sera (b) were measured by enzyme-linked immunosorbent assay. CXCL10 concentrations were significantly increased in synovial fluid and sera of RA in comparison with those of OA. Data were expressed as mean ± standard error. CXCL10, interferon-gamma-inducible protein 10.Back to article page
