| Outline of Final Research Achievements |
Despite the long history since the discovery of Kawasaki disease, its molecular pathogenesis still remains to be elucidated. In our previous study, we showed that at the very beginning of Kawasaki disease, CD4+CD25+FOXP3+ regulatory T cells were significantly decreased. Additionally, several epidemiological evidence suggets the requirement of infection for the development of Kawasaki disease. Based on these concepts, we hypothesized that an initial infection of unknown pathogen decreases T regulatory cells and the second infection of a common pathogen triggers Kawasaki disease onset. Based on this hypothesis, we planned to perform comprehensive DNA/RNA analysis of clinical specimen obtained before the diagnosis of Kawasaki disease. We successfully collected four clinical specimens obtained before the fulfillment of diagnostic criteria; however, we could not identify any pathogenic genomic sequences among these specimens.
