Outline of Research at the Start

成体の脳内では、限られた領域において神経幹細胞から新しいニューロンが持続的に産生されている。これらの新生ニューロンは鎖状に連なって脳内を高速移動し、目的の領域に到達すると成熟し、脳機能の維持に寄与している。脳梗塞などの脳傷害の際にも、一部の新生ニューロンが正常な脳と同様に鎖状に連なって傷害部へと移動する。しかし、その機序の多くは未だ不明である。本研究では、新生ニューロンが鎖状に連なって移動する際のニューロン間の接着に着目し、新生ニューロンが接着しながら移動するメカニズムを解明するとともに、その接着機構への介入によって、成体大脳皮質傷害に対する新たな治療法の開発を目指す。

Outline of Final Research Achievements

In the adult brain, new neurons are continuously generated from neural stem cells in limited areas. These new neurons migrate in chains at high speed through the brain and mature when they reach the target region, contributing to the maintenance of brain function. In the injured brain, some of these new neurons also migrate in chains to the injured area, but the mechanisms remained unknown. In this study, we focused on the adhesion between neurons in chains and developed a new treatment for adult cerebral cortex injury.

Academic Significance and Societal Importance of the Research Achievements

本研究により、なぜ正常脳内では新生ニューロンが集団かつ高速で移動することができるのか、また、なぜ傷害脳内を移動する新生ニューロンは移動効率が低下してしまうのかを明らかになった。さらに、本研究により、傷害脳内を新生ニューロンが効率よく移動することが可能となる方法が見出され、成体大脳皮質傷害に対する新たな治療法の開発につながった。
