| Outline of Final Research Achievements |
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by less social interaction / communication or repetitive behaviors. Despite recent intensive researches, its molecular mechanism remains largely unclear. Recently, our research group succeeded to generate mice model (patDp/+) for ASD that have duplicated chromosome 7B to C region, corresponding to human chromosome 15q11-13 which is one of the responsible locus for ASD. In this study, we addressed the self-other recognition mechanism by using this model and tried to find causative molecule in the brain. Compared to WT mice, patDp/+ mice showed altered brain activity stimulated by the odor of other mice or self. PatDp/+ mice had decreased levels of a specific amino acid in the brain both in adult and postnatal developmental period. These results suggest that the imbalance of amino acids in brain might be a critical role in the social abnormalities found in ASD.
