Outline of Research at the Start

近年、虐待やHikikomoriなど劣悪な生育環境は、種々の精神疾患の危険因子であると言われており、適切なケアの確立は喫緊の研究課題である。これまで様々な動物モデルを用いた基礎研究が展開されてきたが、生育環境が社会的集団生活における行動にどのような影響を与えのるかについては未だ明らかにされていない。本研究では、研究代表者らが近年開発した『社会的集団行動の解析が可能な新システムAR-LABO』と脳領域特異的に神経活動の制御が可能な化学遺伝学を用い、「幼少期生育環境」‐「社会的集団での行動表現型」‐「責任脳領域」の関係を明らかにし、被虐待やHikikomoriの神経基盤の理解を目指す。

Outline of Final Research Achievements

Early life adversities such as abuse and Hikikomori are one of the serious risk factors of various neuropsychiatric diseases. We employed a novel behavioral analysis system “AR-LABO”, which can identify multiple mice in a group-housing condition over long duration, and AI technology to investigate various behaviours of adult male C57BL/6N mice exposed to repeated MS.
We found several interesting behavioural phenotypes, including inappropriate social distance from cagemates, alternation in approach behaviour, which could be observed in an attachment disorder. We are now proceeding DREADD experiments to manipulate hippocampus, amygdala and medial prefrontal cortex to find out the neural network responsible for these behavioral changes in MS mice.

Academic Significance and Societal Importance of the Research Achievements

近年、虐待やHikikomoriなど劣悪な生育環境は、種々の精神疾患の危険因子であると言われており、適切なケアの確立は喫緊の研究課題である。本研究は、虐待及びHikikomori夫々の動物モデルである母子分離マウス及び思春期社会的隔離マウスの社会的集団における行動表現型について、申請者らが独自に確立した新しい行動解析システムのAR-LABOを用いて同定した。さらに化学遺伝学により神経活動レベルと社会的集団における種々の行動との関連を検証するシステムの開発に取り組んだ。得られた研究成果は、被虐待やHikikomoriの神経基盤を明らかにし、そのケア/治療法の開発に繋がる有意義なものである。
