| Outline of Final Research Achievements |
Autism spectrum disorders (ASDs) might reflect an increase in the ratio between excitation and inhibition leading to hyper-excitability of neuronal circuits. Synaptic Vesicle Protein 2A (SV2A) is involved in presynaptic neurotransmitter release. In this project, we clarified that 1) single nucleotide polymorphism of SV2A was associated with low harm avoidance and high novelty seeking in the Temperament and Character Inventory test, 2) Inhibition of SV2A by high dose of levetiracetam induced anxiety in mice. Thus, SV2A might contribute to the psychological function. Furthermore, low dose of levetiracetam attenuated impairments of sociality and object recognition memory in the animal model of ASDs. These findings suggest that levetiracetam might improve behavioral disturbances of ASDs.
