| Outline of Final Research Achievements |
We analysed the mechanisms of autophagy in Nod1 ligand-induced coronary arteritis, one of the mice models of Kawasaki disease we reported previously. First, we found that rapamycin, autophagy incducer, improved coronary arteritis in the mice. Furthermore, in human coronary artery endothelial cells, rapamycin decreased production of inflammatory cytokines such as IL-6 and IL-8. Rapamycin is one of the mTOR (mammalian target of rapamycin) inhibitors, so we did the same experiments in vivo and in vitro by using other mTOR inhibitors. They revealed that other mTOR inhibitors also induced improvement of coronary arteritis and inhibition of cytokine production. These results showed that mTOR inihibitors, autophagy inducers, are possible new treatment with Kawasaki disease.
