| Outline of Final Research Achievements |
We investigated a way of treatment for ASD by using a chromosome duplicated ASD model mouse (15q-dup).
Because the serotonin content in the brain of 15q-dup mouse was decreased from neonatal period, we tried a treatment with a selective serotonin re-uptake inhibitor, fluoxetine, during 3 weeks after birth. The lower sociability and brain 5-HT level were ameliorated in adult 15q-dup mice, but their persistent behavior and repetitive behavior were not. Electrophysiological experiments revealed that 5-HT neurons had more hyperpolarized resting membrane potentials and smaller excitatory glutamatergic inputs in the dosal raphe nucleus in 15q-dup mice compared with the wildtype. In association with the serotonin restoration, neonatal FLX treatment also ameliorated these electrophysiological of 15q-dup mice. （Science Advances, in press）
