Outline of Final Research Achievements |
In this study, we focus on cerebral synoviolin (Syvn) as a ubiquitin ligase (E3) involved in endoplasmic reticulum-related degradation mechanism, the mechanism of septic encephalopathy (SE) was investigated. As a result,1 Metabolome analysis of intracerebral metabolic pathway via Syvn showed a marked decrease in kynurenic acid and a significant increase in kynurenine at 18 hours after SE onset. It became clear that kynurenine plays an important role in inducing the impaiment of the brain. 2 KAT activity by SE was increased, especially, activity of KAT4 significantly increased 18 hours after CLP model creation. Conclusion: Suppression of Syvn and reduction of kinurenine suppresses neuropathy and it may lead to improvement of septic encephalopathy.
