The synovial fluid levels of S100A11 significantly correlate with the levels of anti-CCP in the synovial fluid of RA patients (a). S100A11 is associated with the levels of myeloperoxidase (MPO) (b), citrullinated histone 3 (citH3) (c) and with the activity of peptidyl-arginine deiminase (PAD) enzymes (d) in the synovial fluid of patients with RA (n = 23–30).
