Outline of Final Research Achievements

Functional and structural defects in neuronal synapses are thought to underlie the pathophysiology of autism spectrum disorders (ASD). While more than 50 % of ASD patients suffer from sleep disturbance, relationship between circadian rhythm and ASD etiology is largely unknown. In this study, we focused on 3 circadian clock genes, TIMELESS, NR1D1 and PER3, whose gene abnormalities have been reported in ASD individuals. By the use of mouse models produced by "comprehensive in vivo/in vitro analytical battery" we constructed, we analyzed pathophysiological significance of gene abnormalities of TIMELESS, NR1D1 and PER3 in ASD.

Academic Significance and Societal Importance of the Research Achievements

本研究は、概日リズム障害(時計遺伝子の機能障害)の観点からASDの大脳皮質形成障害・シナプス病態に迫り、新しい病態形成メカニズムの発見を目指した。この着想の発端は、ASD患者の遺伝子解析で、時計遺伝子TIMELESS, NR1D1 and PER3に新規ミスセンス変異を発見したことにある。これらの変異が大脳皮質形成とシナプス動態に与える影響をin vivo/in vitroで包括的に解析した結果、ASDの新たな病態メカニズムの存在が示唆された。
