Outline of Final Research Achievements

Imaging of tau protein, which is one of the major pathological changes in Alzheimer's disease, which is the main cause of neurofibrillary tangles, with PET [11C]PBB3-PET as a control for amyloid negative dementia and Alzheimer's dementia (AD) , Images of healthy elderly people were compared and analyzed. In amyloid-negative dementia, high levels of PBB3 were found in the bilateral parietal lobes, suggesting the accumulation of tau protein with age. Furthermore, in patients suspected neurofibrillary tangle-predominant dementia (NFTD), the spread of tau accumulation was more localized than in AD, and tau accumulation was more prominent in the lateral temporal lobe and posterior cingulate gyrus compared to healthy elderly people. , It was suggested that tau accumulation at the same site may contribute to the appearance of cognitive dysfunction leading to ADL decline.

Academic Significance and Societal Importance of the Research Achievements

神経変性疾患に重要な病理変化である神経原線維変化の主体であるタウ蛋白に結合するPBB3-PETを用いて、臨床的にアルツハイマー病の診断であってもアミロイド集積がない患者群の背景病理をタウ蛋白が関連する嗜銀顆粒性認知症、神経原線維変化優位型認知症などを推察した。更にそれらの群を解析することで、PBB3-PETの有用性を明らかにした。また今後開発されるであろう、アルツハイマー病治療薬の適応を考慮する上で、臨床的には鑑別の難しいアミロイド陰性認知症にも非常に重要な役割をPBB3-PETが果たすことが予想される。
