Abstract
Kawasaki disease (KD) is a febrile disease of childhood characterized by systemic vasculitis, and the levels of many proinflammatory cytokines are elevated in the serum at the acute stage. We investigated the activation of transcription factor NF-kappa B for genes that encode the proinflammatory cytokines in CD14+ monocytes/macrophages and CD3+ T cells in peripheral blood by means of Western blot and flow cytometric analyses. Western blot analysis demonstrated that NF-kappa B activation was more increased in CD14+ monocytes/macrophages than in CD3+ T cells in all children during the acute stage. Flow cytometric analysis revealed NF-kappa B activation in CD14+ monocytes/macrophages was significantly higher than in CD3+ T cells at the acute stage (30.0 ± 16.0% vs 11.4 ± 5.0%, p < 0.01, Wilcoxon test). NF-kappa B activation in CD14+ monocytes/macrophages was significantly decreased after high-dose intravenous immunoglobulin therapy (p < 0.05). The present findings suggest that CD14+ monocytes/macrophages play an important role in the cytokine production during acute KD.
