Outline of Final Research Achievements |
The underlying neural mechanisms of neurodevelopmental disorders including autism spectrum disorder (ASD) are poorly understood. We examined an involvement of microglia in ASD using mice with paternal duplication (patDp/+) corresponding to human chromosome 15q11-q13. Iba1, a microglial activation marker, was decreased in the basolateral amygdala in patDp/+ mice at postnatal day 7. Perinatal treatment with minocycline, a microglial modulator, restored the Iba1 expression in the basolateral amygdala and reduced anxiety-related behaviors in adolescence. Further, early postnatal treatment with a selective serotonin reuptake inhibitor, which has been reported to directly affect microglial functions, ameliorated a deficit in social interaction behavior in adolescence. The results of the present study suggest important roles of microglia in pathophysiology of neurodevelopmental disorders and provide a key piece of information to develop novel microglia-related drugs for these disorders.
