Outline of Final Research Achievements

The purpose of this study was to clarify the relationship between social behavioral deficits and the GABA signaling using two mice models prenatally exposed to valproic acid or ethanol. Administration of GABAA receptor inhibitors to these model mice showed improvement in social behavioral deficits. Abnormal expression of GABA-related genes was detected in mice exposed to valproic acid. We found that abnormal GABA signaling in utero affected social behavioral deficits.

Academic Significance and Societal Importance of the Research Achievements

本研究は、胎生期のGABAシグナル異常が生後の社会性行動障害に関連することを薬剤曝露による自閉症モデルマウスを用いて明らかにしたものである。これまでの先行研究において、生後脳における興奮/抑制のアンバランスは研究されてきたが、薬剤曝露による胎仔脳のGABAシグナルによる興奮/抑制のアンバランスに着目したものはなく、薬剤曝露による自閉症モデル動物に関して、新たな知見を得ることができ、社会性行動障害の病態解明と治療薬開発に貢献することが期待される。
