Triptolide, a diterpenoid triepoxide from Tripterygium wilfordii Hook F (TWHF), has been proven to have potent immunosuppressive and anti-inflammatory activities. It has been clinically used to treat patients with rheumatoid arthritis (RA), in which chemokines play an important role in immune and inflammatory responses. To investigate the effect of triptolide on MCP-1, MIP-1α and RANTES, we used complete Freund's adjuvant to induce adjuvant-induced arthritis (AA) in rats. AA in rat is a useful experimental model of human RA. Our data show that the thickness of arthritic ankle decreases with administration of triptolide. Both mRNA and protein levels of MCP-1, MIP-1α and RANTES in synovial tissue of rats with AA are significantly higher than those in normal rats. mRNA levels of MIP-1α and RANTES increase in peripheral blood mononuclear cells of rats with AA in comparison with those in normal rats, whereas no MCP-1 mRNA can be detected. Triptolide can significantly inhibit rat AA induced over-expression of MCP-1, MIP-1α and RANTES at both mRNA and protein levels in a dose-dependent manner. These results may contribute to the therapeutic effects of triptolide in rheumatoid arthritis.
