| Outline of Final Research Achievements |
Synovitis, an inflammatory disorder of the synovial membrane, frequently accompanies internal derangement and/or osteoarthritis in temporomandibular joint (TMJ) and has been suggested to be a key feature of intracapsular pathological conditions of TMJ. To identify inflammatory factors and signaling pathways associated with synovitis, we investigated the gene expression profiles and the signaling pathway analysis in TMJ synovial fibroblasts treated with inflammatory cytokines. Signaling pathway analysis indicated that the expressions of inflammatory factors were stimulated by NFκB and PAMK. Next, we investigated the effects of inhibitors of cyclooxygenase, NFκB, and PAMK. The expressions of inflammatory factors were decreased in synovial fibroblasts treated by those inhibitors. The approach used in this study may be useful for revealing the inflammatory networks and the effect of the anti-inflammatory drugs in the synovitis of the TMJ.
