Autoantibodies against native versus citrullinated histones in CCP− subjects. IgG levels against native and citrullinated histone H1 (A), histone H2A (B), histone H2B (C), histone H3 (D), and histone H4 (E), measured by ELISA for CCP− rheumatoid arthritis subjects homozygous at rs2240335 were compared by plotting anti-citrullinated histone antibody levels on the Y axis and anti-native histone antibody levels on the X axis. For all panels, n = 27 GG and n = 14 TT.
