Inhibitory Effect of Kamisopunghwalhyeol-tang (Jiaweishufenghuoxie-tang) on Inflammatory Cytokine Production and $NF-{\kappa}B$ and AP-1 Activation in Cultured Humau Fibroblast-like Synoviocytes

가미속풍활형탕이 human fibroblast-like synoviocytes 내 염증 유발 cytokine과 전사인자에 미치는 영향

Objective : This study was carried out to investigate the effects of Kamisopunghwalhyeol-tang (Jiaweishujenghuoxie-tang; Kami-SPHHT) on the immunity responses of the Synoviocytes isolated from the patients on rheumatoid arthritis. Methods : Cells were stimulated by $Interleukin-1{\beta}$ and Tumor Necrosis $Factor-{\alpha}$ in the presence or absence of Kami-SPHHT, and then induced cytokine mRNA levels were determined by RT-PCR and real-time quantitative RT-PCR. Results : Levels of $IL-1{\beta},{\;}IL-6,{\;}TNF-{\alpha}$, COX-2, and NOS II mRNA expressions significantly decreased in Kami-SPHHT treated cells compared to non-treated control cells. Also, DNA-binding activity of $NF-{\kappa}B$ and AP-l decreased in Kami- SPHHT treated hFLSs. Conclusion : These results suggest that Kami-SPHHT may be involved in anti-inflammatory reactions by inducing cytokine gene expression in synoviocytes, and further in vivo examination on its efficacy can provide potential application for the treatment of rheumatoid arthritis.
