| Outline of Final Research Achievements |
Recently, there is an increasing interest in the interaction between indigenous microbes and the host, called the inter-kingdom signaling.
In this study, we found that LED209, an inhibitor of CA-mediated IKS, ameliorated mucosal inflammation in animal models of inflammatory bowel diseases, and that biologically-active serotonin were present in the gut lumen , but some of them were inactive and glucuronide-conjugated.
These results suggest that the CA-mediated IKS might play an important role in pathophysiology of inflammatory bowel diseases. They also indicate that gut microbes are indispensable for the generation and metabolism of gut lumen serotonin.
