Outline of Final Research Achievements

Glucose metabolism and electron transport chain-related mitochondrial activity may be differentin in Alzheimer’s disease (AD). To test this hypothesis on the AD pathophysiology, we measured the availability of mitochondrial complex-I (MC-I) with the novel positron emission tomography (PET) probe [18F]BCPP-EF that binds to MC-I.Thirty-two AD patients were scanned semi-quantitatively with double PET tracers (BCPP and FDG). Inter and intrasubject comparisons of the levels of MC-I activity, glucose metabolism were performed.The [18F]BCPP-EF SUVR, but not the [18F]FDG SUVR, was significantly lower in the parahippocampus in AD. Positive correlations between [18F]BCPP-EF SUVR and [18F]FDG SUVR were observed in several brain regions except the parahippocampus. Mitochondrial dysfunction in the parahippocampus was shown in early-stage AD. Mitochondria-related energy failure may precede glycolysis-related hypometabolism in the pathologically-confirmed, early neurodegenerated region in AD.

Academic Significance and Societal Importance of the Research Achievements

新規放射性薬剤[18F]BCPPを用いたアルツハイマー病(AD)の生体脳におけるミトコンドリア機能の可視化は新規の試みである。ADでは初期から脳内ミトコンドリア障害を認めることが報告されており、今回の検討にて、ADの初期変性領域(海馬傍回)においてミトコンドリア機能障害をPETにて生体脳にて捉えることができた。また、ミトコンドリア機能障害と認知機能障害との関連を示した。以上より、BCPP-PETはADの早期診断と病態把握に極めて有用であることが期待される。近年、抗酸化作用をもつ薬剤への関心も高まっており、その薬剤の病態抑制の効果判定に関して、客観的な画像的評価系として貢献する可能性がある。
