Outline of Final Research Achievements

Although alterations in central glutamatergic neurotransmission are implicated in schizophrenia, in vivo visualization of glutamatergic neurotransmission is challenging. Using PET radioligands that we recently developed, we demonstrated possibilities to quantify status of glutamatergic neurotransmission including AMPA receptor in the living brain. Utilizing glutamate-PET as well as MRS, we investigated aberrant glutamatergic neurotransmission in patients with schizophrenia.

Academic Significance and Societal Importance of the Research Achievements

脳内神経伝達機能は統合失調症をはじめとする多くの精神疾患において重要な役割をもつと考えられているが、生体内でその変化を捉える方法は限られている。我々は新しいPET撮像手法を用いてAMPA受容体をはじめとする脳内グルタミン酸神経伝達の変化を捉える方法を開発し、その技術を応用することにより、統合失調症の病態メカニズムを解明できる可能性を示した。今回の研究により、脳内グルタミン酸神経伝達異常を対象とした統合失調症の新たな治療法開発につながると期待される。
