Abstract

Intravenous administration of subarthritogenic doses of anticollagen IgG and adjuvant-sensitized spleen cells to syngeneic naive rats induces an erosive arthritis in recipients. The onset of the clinical disease in recipients is rapid and the disease is severe when compared to those recipients receiving cells alone. Immunocytochemical analysis of the knee synovium indicates the accumulation in the adipose tissue of Ia+ (ED1+)macrophages, OX-19+ T lymphocytes, and neutrophils. A large proportion of the lining cells of the proliferative synovium are Ia+. The knee synovium is extremely edematous and contains fibrin. If recipient rats are decomplemented, clinical disease is delayed and the number of mononuclear and polymorphonuclear cells accumulating in the synovium is decreased. Similar results are observed if recipient rats are treated with anti-Ia+ antibody. However, anti-Ia+ treatment does not induce depletion of serum complement.
