Outline of Final Research Achievements

In the adult mammalian brain, newborn neurons generated from neural stem cells actively migrate toward their final destinations, where they differentiate into mature neurons and contribute to brain functions. In this study, we have studied 1) the expression patterns and functions of extracellular matrix molecules in neuronal migration in the adult brain, 2) the regulatory mechanisms for expression of extracellular matrix molecules, and 3) the function of PTPsigma and its substrate, tyrosine-phosphorylated cortactin (pY421-cortactin), on growth cone extension and subsequent migration in newborn neurons.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、生後の脳におけるニューロン移動制御の新しいしくみを明らかにしたものであり、神経科学分野の重要な知見となる。また、脳傷害が生じると、生後の神経幹細胞から産生された新生ニューロンは、傷害部へと移動して失われたニューロンを再生することから、本研究の成果はニューロン再生を促進する方法の開発に貢献する可能性がある。
