Abstract Introduction Anti-citrullinated protein antibodies have a diagnostic role in rheumatoid arthritis RA however little is known about their origins and contribution to pathogenesis. Citrullination is the post-translational conversion of arginine to citrulline by peptidyl arginine deiminase and increased citrullination of proteins is observed in the joint tissue in RA and in brain tissue in multiple sclerosis MS . Methods We applied synovial and myelin protein arrays to examine epitope spreading of B cell responses to citrullinated epitopes in both the collagen-induced arthritis CIA model for RA and the .
