Outline of Research at the Start

褐色脂肪組織の熱産生機能の亢進は、持続的かつ強力な抗肥満効果を示す事が知られている。本研究の目的は、運動が褐色脂肪組織のアミノ酸利用とそれに引き続く熱産生能に与える影響を解明して、その効果と同等の効果を持つ腸内細菌(プロバイオティクス)を統合オミクス解析により探索し、肥満症治療への可能性を検証する事である。運動による体重減少効果の新たな分子機序を解明し、腸内細菌制御により運動を模倣する効果を再現できれば、肥満症治療に対する新たな変革をもたらす事が期待される。

Outline of Final Research Achievements

The purpose of this study is to search for gut bacteria with the same effect as exercise and to verify the possibility of treating obesity. In order to identify gut bacteria that increase with "exercise", obese model mice were subjected to treadmill exercise, but those exercise did not affect obesity, and it was not possible to identify the exercise-mimicking bacteria. Oral administration of Bacteroides species to fat diet loading obese model mice suppressed obesity, improved branched-chain amino acid metabolism in brown fat cells, and demonstrated the possibility of reproducing thermogenesis that occurs with exercise.
By investigating the relationship between thinness/obesity and gut microbiota in humans, we found some novel evidence of gut flora type in association with thin elder person.

Academic Significance and Societal Importance of the Research Achievements

運動が褐色脂肪細胞のアミノ酸利用とそれに引き続く熱産生能に与える影響を解明した。新規の菌の発見はできなかったが、その効果を持つ腸内細菌(プロバイオティクス)を特定しており、肥満症治療への応用を目指した研究基盤になると考えている。腸内細菌制御により肥満予防の可能性を示したことになり、近い将来に「腸からの新たな肥満管理法・治療法」での変革をもたらす事が期待できる。
