title: Epitope specificity of antibody response against human type II collagen in the mouse susceptible to collagen-induced arthritis and patients with rheumatoid arthritis.
abstract: The presence of species-specific and species-non-specific (common) epitopes has been demonstrated on type II collagen (CII) using monoclonal antibodies. In this study, we investigated the role of antibody response to some species-specific and common epitopes in mice immunized with human CII for the induction of collagen-induced arthritis (CIA). Antibody responses to species-specific epitopes in arthritic mice appeared significantly higher than that in non-arthritic mice. However, no significant difference of antibody responses to common epitopes was found between arthritic and non-arthritic mice. Monoclonal antibody reactive with one of the common epitopes exhibited the ability to induce arthritis in mice previously given the primary injection of CII, indicating the involvement of this epitope in the induction of CIA. Finally, we investigated the epitope specificity of anti-human CII antibody present in serum samples of patients with rheumatoid arthritis and relapsing polychondritis, and found antibodies to some common epitopes.
