Outline of Final Research Achievements

This study was designed to verify a hypothesis that aging-related cardiomyopathy (ARC) would be developed due to chronic inflammation based on the relation between sympathetic nerve and inflammation in cardiac fibroblasts. We used beta 2 adrenergic receptor knockout (β2ARKO) mice for this study and observed a shortness of life, a decrease in left ventricular diastolic function and an increase in cardiac fibrosis in accordance with age, compared to control mice. On the other hand, there was no significant difference between aged control and β2ARKO mice in senescence-associated secreted phenotypes. Those results were different from the hypothesis and suggested that β2AR might have a protective role in the development of ARC due to cardiac diastolic dysfunction with fibrosis.

Academic Significance and Societal Importance of the Research Achievements

本研究において、β2アドレナリン受容体欠失に伴い、マウスの寿命が短縮したことから、β2アドレナリン受容体を活性化させることにより、寿命を延長する可能性があることが示唆された。また、β2アドレナリン受容体は、心臓において拡張能の維持を介してaging-related cardiomyopathyを抑制することが明らかとなった。β2アドレナリン受容体アゴニストは気管支喘息に対する治療として貼付剤が一般的に使用されており、この既存の薬剤が健康寿命を延長させる治療へ展開できる可能性を示唆している。
