Outline of Final Research Achievements |
Precise neural circuits that are formed in the central nervous system, such as the brain and the retina, are important for the function of the central nervous system. However, the mechanism is poorly understood. We found that Afadin, an intercellular adhesion factor, contributes to the function of retinal neural function. Furthermore, one of the key factors in the light signaling pathway in the retina was ectopically localized and expressed in the retina in Afadin cKO mice. These results indicate that Afadin is required for the formation and function of retinal neural circuits through the accurate expression and localization of key factors in synaptic transmission.

Academic Significance and Societal Importance of the Research Achievements |
OFF経路の異常 Afadinは様々な組織で発現・機能することが知られており、その分子メカニズムについても解明が進んでいる。その様に細胞全般に発現し、かつ分子メカニズムも知られた因子が特定の神経回路形成に寄与するという観察結果は意外性が高く、これまでもほとんど報告例がない。このことから、これまで知られていなかった新しい神経回路形成メカニズムが明らかになる可能性が期待される。本研究により選択的神経回路形成メカニズムの一端が明らかになれば、神経回路形成異常によって引き起こされる疾患の治療法の確立にもつながり、社会的な貢献も見込まれる。
