Outline of Final Research Achievements |
We tried to identify for nondenaturing proteins recognized by CCP-Ab1, an autoantibody derived from rheumatoid arthritis patients. Our findings demonstrated that a monoclonal ACPA (CCP-Ab1) bound to fibrinogen under native conditions. Next, we made the amino acid sequences of CCP-Ab1 revert to their germline sequences (CCP-Ab1 GL-rev) and analyzed its binding activity to the fibrinogen. CCP-Ab1 GL-rev did not bound to fibrinogen. These results suggested that CCP-Ab1 was generated by the stimulation of B-cells with citrullinated denatured protein and it acquired the reactivity to fibrinogen during B-cell differentiation by somatic hypermutation.
