Outline of Research at the Start

自閉スペクトラム症などの発達障害を認める児童は、過食や特有の偏食をきたし治療抵抗性の高度肥満を認める場合が珍しくない。レット症候群は、自閉的な特徴を有する疾患のひとつであり、肥満を認めるという報告がある。レット症候群のモデルとなるMecp2ノックアウトマウスまたはMecp2+/-マウスを用いて肥満形成メカニズムを解明することで、発達障害児の食行動の原因解明に示唆を与え、ターゲットとなる分子標的治療薬の開発に貢献することが期待される。

Outline of Final Research Achievements

Rett syndrome is caused by an abnormality in the Methyl-CpG binding protein 2 gene (Mecp2), which plays a central role in transcriptional regulation. It has been reported that a mild form of Rett syndrome is more likely to be complicated by obesity. To elucidate the mechanism of obesity formation, we investigated the molecular mechanisms of hypothalamic regulation of feeding and reward system regulation of eating behavior using Mecp2+/- mice. We found that Mecp2+/- mice have a high preference for a high-fat diet, which leads to severe obesity and glucose intolerance due to overeating, and High-fat diet may induce impairment of the hypothalamic feeding suppression system and impaired regulation of eating behavior in the dopamine reward system in Mecp2+/- mice.

Academic Significance and Societal Importance of the Research Achievements

自閉症性発達障害児は過食や特有の食事嗜好性を認めることが多く、治療抵抗性の肥満を認めることがある。本研究が中枢性の治療抵抗性肥満のモデルとして肥満研究における有効性が認められれば、ターゲットとなる分子標的に対する治療薬の開発に貢献することが期待される。
