Outline of Research at the Start

本研究は、重症心不全症例においてその不全心から産生されるナトリウム利尿ペプチドは、心臓のエネルギー基質としてケトン体利用を亢進させる因子となりうるのか、検討を行う。まずは臨床研究として、不全心においてナトリウム利尿ペプチドがエネルギー基質としてケトン体利用を亢進させる因子となりうるか、共分散構造解析を用いた解析を行う。また基礎研究として、圧負荷誘発心不全モデルマウスを用いることにより、ナトリウム利尿ペプチド補充療法による心組織におけるケトン体取り込み亢進の確認を行う。本研究の成果は、ナトリウム利尿ペプチド のケトン体利用亢進による心臓エネルギー代謝活性作用を介した新たな治療戦略となる。

Outline of Final Research Achievements

In the clinical research, we first demonstrated that blood NP levels in heart failure patients strongly correlate with ketone body levels. Furthermore, in patients with chronic heart failure, we showed that angiotensin receptor neprilysin inhibitors (ARNI) play an important role to improve insulin resistance as natriuretic peptide (NP) supplementation therapy. In animal studies, continuous administration of NPs in a high-fat diet-fed (HFD) obese mouse model ameliorated fatty liver and improved systemic insulin resistance via re-browning of whitened BAT. Locally in the heart, we demonstrated that NPs reduce fatty acid overload to mitochondria and improve insulin resistance.

Academic Significance and Societal Importance of the Research Achievements

心不全では体内でケトン体の産生亢進が生じるが、このケトン体による心保護効果に近年注目が集まっている。本研究により、アンジオテンシン受容体ネプリライシン阻害薬(ARNI)をはじめとしたNP補充療法は、重症心不全時にケトン体産生を介した心保護作用を発揮する可能性が示唆された。また、インスリン抵抗性は心不全の発症、進展と密接に関与している。本研究は、NP補充療法が心不全患者に対するインスリン抵抗性改善を介したあらたな治療手段となりうることを示した。
