Abstract
Molecular biological and immunochemical techniques have been used to study the synthesis of complement components by synovial tissue from patients with rheumatoid arthritis or osteoarthritis and by normal synovial tissue from a patient undergoing patellectomy. Using Northern and dot-blot analyses, mRNAs coding for C1-inhibitor, C2, C3, C4 and factor B have been detected, but not for C5. Quantitative analyses of the data have not shown any significant differences in the steady state levels of any of the mRNAs in synovium from rheumatoid arthritis and osteoarthritis patients. When synovial membrane fragments from rheumatoid arthritis, osteoarthritis patients or normal synovium were cultured in vitro, synthesis of C1-inhibitor, C2, C3, C4 and factor B detected by ELISA and C2, C3 and factor B were shown to be functionally active. This study thus provides conclusive evidence that synthesis of complement components occurs locally within normal and inflamed synovial tissue. The local synthesis of complement within normal synovial joints may be of importance in their defence against infection, whereas in inflamed joints it may contribute to the inflammatory response.
