Outline of Research at the Start

レム睡眠は様々な疾患の発症や加齢に伴い減少する。近年の研究から、レム睡眠が脳の恒常性維持や記憶の固定化など、脳機能に重要な役割を担うことが明らかになりつつある。しかしながら、レム睡眠を有効に増やす方法はない。我々は、特定のエサがマウスのレム睡眠を有効に増加させる可能性を見出した。そこで本研究では、食事がレム睡眠に影響を及ぼすメカニズムを、我々がこれまでに明らかにしてきたレム睡眠制御回路に注目しながら明らかにする。本研究により、食事・睡眠・健康の関係をつなぐ革新的なメカニズムの発見を目指す。

Outline of Final Research Achievements

Sleep architecture (REM and non-REM sleep cycles), an important factor in determining sleep quality, is affected by aging and disease onset. Since changes in sleep quality, in addition to sleep quantity, are risk factors for various diseases, including dementia, the development of effective improvement methods is required. We found that certain diets may effectively increase REM sleep and slow wave sleep (deep non-REM sleep) in mice. Our efforts to elucidate the mechanisms by which diet influences sleep architecture have led to a better understanding of the neural circuits involved and what elements of the diet act on sleep architecture.

Academic Significance and Societal Importance of the Research Achievements

食事が脳の生理状態に与える影響について、睡眠を介した新たな機能性に光を当てる本研究は、「食事」「睡眠」「健康」の関係をつなぐメカニズムの解明に貢献した。睡眠改善をうたった商品の科学的根拠などが問題視される中、良質な睡眠を導くことができる食事療法が開発できれば、睡眠障害の改善に大きく貢献できると期待される。精神・神経系疾患に睡眠障害はつきものだが、根本的治療の見通しが未だに立たない疾患が数多く存在する。本研究を起点として、食事の力で認知症等の疾患の予防・治療が導けることが明らかとなれば、医学的にも大きな進歩となると考えられる。
