Outline of Research at the Start

神経軸索の再生機構の理解は、損傷した神経の再生医療に繋がることから、社会的要請度の高い研究課題である。しかし、神経軸索再生を促進・抑制するシグナルの実体および制御機構は未解明である。これまでに、線虫C.elegansをモデル動物として、軸索再生を制御するシグナル伝達系として、JNK MAPキナーゼ(MAPK)経路、p38 MAPK経路、サイクリックAMP(cAMP)経路、PKC経路、低酸素経路、Rho→ミオシン経路、などを世界に先駆けて見出した。本研究の概要は、線虫をモデル動物として、これらのシグナル伝達経路の有機的連携によって構成される、神経の軸索再生を制御するシグナル伝達ネットワークの全容解明を行う研究である。

Outline of Final Research Achievements

Regeneration of severed nerves is a conserved mechanism across animal species. Based on previous analyses using C.elegans, we identified the JNK MAP kinase (MAPK), cyclic AMP (cAMP), PKC and myosin signaling pathways that regulate axon regeneration. In this study,using C.elegans as a model animal, we have revealed a signaling network that regulates nerve axon regeneration, which consist of an organic linkage of these signaling pathways.

Academic Significance and Societal Importance of the Research Achievements

神経軸索の再生機構の研究は、医学的には事故や疾患による神経切断や欠損の治療法を開発する上で重要であり、社会的にも喫緊の課題である。本研究により、線虫において、神経軸索再生の中心シグナルの一つとして働くJNK MAPK経路の周辺で機能するシグナル系として、Wntシグナル、フェロモン様シグナル、タンパク質分解系を同定した。これらのシグナル系が構成するネットワークによる、神経軸索再生制御機構が解明された。今後、本研究で得られた成果は、神経損傷などの患者に対する治療を開発する上で、基礎生物学的知見として有用であると期待される。
