Outline of Final Research Achievements |
The number of diabetic patients is exploding worldwide, and the number of patients suffering from its complications is also increasing. Cognitive dysfunction is a common complication of the central nervous system in diabetic patients, but there are few treatment options and the pathophysiology is not well understood. It is important to elucidate the mechanisms of cognitive dysfunction in diabetic patients, not only in Japan, which has become a hyper-aged society, but also in other developed countries with aging populations. This study is also of great academic significance because it is the result of the use of technology that enables the spatio-temporal regulation of specific nervous system cell functions using adeno-associated viral vectors and chemical genetic techniques.

Academic Significance and Societal Importance of the Research Achievements |
糖尿病患者の数は、全世界的に爆発的に増加しており、その合併症に悩まされる患者の数も多くなっている。糖尿病患者にみられる中枢神経系の合併症として認知機能障害があるが、その治療法は少なく、病態生理学的な理解も進んでいない。糖尿病患者にみられる認知機能障害のメカニズムを明らかにすることは、超高齢社会となった日本だけではなく、今後、高齢化が進む先進国においても重要な課題である。また、本研究は、アデノ随伴ウイルスベクターと化学遺伝学的手法を用いて、特定の神経系細胞の機能を時空間的に調節できる技術を利用した結果であり、学術的意義も高いと考えている。
