Outline of Final Research Achievements

"Synapses", which link neurons in the brain, are crucial structures in memory and several kinds of neuropsychiatric diseases. In this study, we could understand the functional roles of C1q family molecules, novel secreted-type synapse organizers we originally identified, in the brain more deeply. In particular, we found that Cbln1 and C1qL1, members of C1q family molecules, dynamically behave in response to neuronal activities to regulate cerebellar synapse circuits. I hope that our findings provide useful information to understand general and novel mechanisms for the synaptic integrity in the CNS.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、「シナプス形成・機能を担うC1qファミリー分子の普遍的かつ新しい動作原理」を確立するための有益な情報を提供しうるものと期待される。近年、シナプスは記憶の形成過程やアルツハイマー病や統合失調症をはじめとする様々な精神神経疾患の病態発現に深く関わる部位として、科学的のみならず臨床的にも注目されている。そのため、シナプス形成・機能の詳細な分子機構を追究した本研究の成果は、将来、種々の精神神経疾患や、認知症および加齢に伴う記憶障害への有効な治療開発につながる可能性も期待される。
