Outline of Final Research Achievements |
Bipolar disorder is a mental disorder that causes mood shifts that include manic episodes (extremely elevated or irritable moods) and depressive episodes. The etiology of bipolar disorder has not been completely elucidated. Recently, neuroinflammation is associated with etiology and pathophysiology of neurodegenerative diseases as well as mental disorders. Also, neuroinflammation is caused by the excessive activation of microglia and induces neuronal dysfunction and cell death. We showed that NG2 oligodendrocyte progenitor cells is related with the maintenance of neuronal function and the pathogenesis of bipolar disorder through regulating the activation of microglia.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、NG2陽性オリゴデンロサイト前駆細胞が脳内炎症(ミクログリア活性化)制御を介して脳内環境保全に関わるという成体脳での新たな役割を見出すことに成功した。さらに、本細胞が双極性障害の発症に関わる可能性についても示した。これらの成果は、双極性障害の原因究明の一助となり、また、新たな治療法開発のためのターゲット情報を提供するものであると考える。
