Outline of Final Research Achievements

We generated and analyzed a renal ischemia and reperfusion model in mice lacking adiponectin or T-cadherin. Our study clearly showed that adiponectin/T-cadherin system played a significant role in maintenance for vascular barrier function and homeostasis of vascular pericytes. Furthermore, we established ELISA system to measure soluble T-cadherin in bloodstream and demonstrated the existence of three forms of soluble T-cadherin (130-kDa, 100-kDa, and 30-kDa). Soluble T-cadherin concentrations were significantly correlated with various clinical parameters, suggesting that soluble T-cadherin is a novel biomarker.

Academic Significance and Societal Importance of the Research Achievements

本研究により、アディポネクチン/T-カドヘリンシステムは腎保護作用を有しており、慢性腎臓病や糖尿病腎症の予防・治療に応用できる可能性を示した。また、可溶性T-カドヘリンを測定することで、糖尿病や心疾患の新たなバイオマーカーとしての応用が期待される。
