Abstract:With the aim of developing a new enzyme-linked immunosorbent assay test to detect autoantibodies in the sera of rheumatoid arthritis patients with a high sensitivity and specificity using synthetic citrullinated peptides of fibrin (which is abundant in rheumatoid synovium) as antigenic substract, peptides belonging to α- and β-fibrin chains were selected by computer-aided prediction of antigenicity and epitope mapping and synthesized in solid phase. We analysed by enzyme-linked immunosorbent assay 133 sera from patients with well-characterized rheumatic diseases, including 67 patients with rheumatoid arthritis. The results of the immunoassays reported highlight the usefulness of fibrin-related peptides in rheumatoid arthritis diagnosis and, especially, the ability and specificity of the [Cit621,627,630]α-fibrin(617–631) (αfib617) peptide sequence to recognize the autoantibodies that are present in rheumatoid arthritis patients.
