Outline of Final Research Achievements

Sepsis, is underlying endothelial dysfunction associated with excessive activation of systemic inflammation and blood coagulation, leads to multiple organ damage. In this study, we have focused on the transcription coactivator Yes-associated protein (YAP) in endothelial cells and investigated whether its activation ameliorates vascular endothelial dysfunction and multiple organ damage.
Our sepsis model mice exhibited organ damage and increased vascular permeability, but we could not evaluate YAP activation. Moreover, by using cultured vascular endothelial cells, we found that YAP activation occurs upon Lipopolysaccharides (LPS) stimulation and demonstrated that YAP is involved in the expression of inflammation-related genes.
These results indicated that septic organ damage and increased vascular permeability may be ameliorated by the regulating YAP activation in endothelial cells.

Academic Significance and Societal Importance of the Research Achievements

敗血症症状や臓器障害を抑えることができる有効な治療法はなく、その開発は医学的課題である。これまで抗サイトカイン療法、抗炎症療法、抗血液凝固療法が試行されたが、十分な成果は得られていない。本研究では、血管内皮細胞のYAPの活性化制御によって敗血症時の臓器障害や血管透過性亢進が抑制できる可能性を見出した。特に、細菌由来成分や傷害関連分子パターンにより血管内皮細胞のYAPが活性化すること、また薬剤によるYAP抑制が血管内皮細胞の炎症応答を抑えることを明らかにした。これらの結果は、敗血症の新しい治療標的や治療法の開発につながると期待される。
