Summary: | Objective: Kawasaki disease (KD) is an acute febrile vasculitis of unknown etiology that may lead to cardiovascular disorders. High-dose intravenous immunoglobulin (IVIG) therapy is well established as a standard therapy for KD. Tumor necrosis factor- alpha (TNF- alpha ) is responsible for the pathogenesis of acute KD. We examined whether or not IVIG inhibits TNF- alpha -induced activation of transcription factor NF- Kappa B, a factor that is essential for the expression of proinflammatory cytokines, in human coronary artery endothelial cells (CAEC). Methods: The inhibitory effect of IVIG on NF- Kappa B activation induced by TNF- alpha was evaluated by Western blot analysis and ELISA. Moreover, the inhibitory effects of IVIG on I Kappa B alpha degradation, interleukin-6 (IL-6) production, and E-selectin expression induced by TNF- alpha were evaluated by Western blot analysis, ELISA, and flow cytometry, respectively. Results: Western blot analysis and ELISA demonstrated that IVIG inhibits NF- Kappa B activation induced by TNF- alpha in CAEC. Moreover, IVIG inhibited I Kappa B alpha degradation, IL-6 production, and E-selectin expression induced by TNF- alpha in CAEC. Conclusion: The data suggest that IVIG inhibits NF- Kappa B activation induced by TNF- alpha in CAEC, thereby possibly modulating IL-6 production and E-selectin expression. |
