Outline of Research at the Start

脳や網膜を含む中枢神経系の構築と機能発現の分子メカニズムの理解は、神経科学研究において重要な課題の一つである。網膜の細胞運命決定と成熟、ならびに選択的シナプス形成に関わる因子を、発生期マウス網膜を用いたシングルセルRNA-seq解析によって、発生過程の遺伝子発現プロファイルを一細胞レベルの解像度で可視化することによって同定し、それらの機能とその作用メカニズムを生体レベルで明らかにし、中枢神経系の発生の分子メカニズムや網膜視覚回路の機能発現の理解を進めることを目的とする。

Outline of Final Research Achievements

We have studied molecular mechanisms underlying retinal development, including neuronal and glial cells, synapse formation, and retinal degeneration. In the current study, we identified candidate genes involved in retinal development and function by scRNA-seq analysis. We analyzed their possible functions in the mouse retina. We generated knockout and double-knockout mice and performed electrophysiological analysis and histological analysis. We carried out inducible Muller glial cell-specific Rax knockout mice. We found that ax suppresses inflammation in Muller glial cells and regulates retinal homeostasis. We reported these results as a research journal paper.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は、中枢神経系における発生と機能の分子メカニズムの理解の進歩に貢献するとともに、網膜変性症を含む失明にいたる網膜疾患の治療法開発の基盤となると期待される。
