Outline of Final Research Achievements

In this study, we have been developing an electrochemical biosensor for beta-amyloid peptide, which is believed to be a causative agent for Alzheimer's disease, in order to achieve the early diagnosis of Alzheimer's disease. By using a peptide which promotes the fibrillization of beta-amyloid peptide, we succeeded in developing one of the highest sensitive be-ta amyloid sensor that does not use be-ta amyloid antibody.
Since we have not reached our final goal to measure beta-amyloid peptide in plasma, further investigation is now under way.

Academic Significance and Societal Importance of the Research Achievements

アルツハイマー病は、根本治療薬がないため、出来るだけ早期の発見が望まれるが、現状、有効な早期診断法は開発されていない。本研究で開発を目指す測定系は、健康診断の1項目として採用できるよう少量の血液から迅速、簡便、安価にアミロイドβを測定するものであり、開発に成功すれば、多くの人々のアルツハイマー病の発症リスクを定期的に評価できる。早期に発見することで、早期に対策をし、患者のQOLをできるだけ高く維持することが可能になると考えられる。
