Outline of Final Research Achievements |
Thermogenic fat cells, including brown and beige adipocytes, increase energy expenditure and contribute to the prevention and mitigation of obesity and diabetes. Recent studies have also revealed that thermogenic fat cells actively consume glucose and regulate systemic glucose metabolism via endocrine functions. To date, the systemic metabolism-modulating effects of thermogenic fat cells on sugar intake behavior and the mechanisms mediating these effects remain unclear. In this study, we generated animal models with activated or deficient thermogenic fat cells and evaluated sugar intake in each model. We have also elucidated mechanisms by which thermogenic fat cells regulate sugar intake.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、食行動科学的な側面から糖質摂取における熱産生脂肪の役割を検討することにより、従来の代謝研究では明らかにすることのできない、熱産生脂肪の新たな役割の解明に挑戦した。 熱産生脂肪細胞を活性化させることで、エネルギー消費量や耐糖能を亢進させることに加え、糖質の摂取量を抑制することが可能であれば、エネルギーの消費と摂取の両面から、肥満や糖尿病をはじめとする生活習慣病の改善にアプローチできる介入法の開発につながる。 本研究で得た知見をもとに糖質摂取に関わる分子基盤を明らかにすることは、より実践的な食事・栄養指導の開発につながる。
