Outline of Final Research Achievements

The aim of this work is to evaluate the association between tau protein related pathology and neural dysfunction using positron emission tomography (PET) and magnetic resonance spectroscopy (MRS) in tauopathy patients. First, we validated the quality of spectra acquired by advanced MRS method in healthy human subjects. Secondly, we performed tau PET and advanced MRS in tauopathy patients. Results suggested that there were some associations between tau protein accumulations measured by PET and neural dysfunction measured by MRS.

Academic Significance and Societal Importance of the Research Achievements

異常タウ蛋白が脳に与える障害の有無を検討するため,ポジトロン断層撮像法(PET)と磁気共鳴スペクトロスコピー(MRS)を用いた評価を行った.PETはタウ蛋白を検出するための薬剤を用いて行い,MRSは高感度の撮像法を用いた.タウPETはタウオパチー患者における信号集積の上昇を同定することができた.MRSはタウオパチー患者において,脳内代謝物が病状を反映するマーカーとして使用できる可能性が示された.PETとMRSを併用することで,タウ蛋白が脳にダメージを与えうることが示唆され,タウ病態の理解をすすめることができた.今回得られた知見は,タウ蛋白をターゲットとした治療法開発に役立つものと考える.
