Outline of Final Research Achievements |
The size of the elderly population of Japan is increasing at an alarming rate and the number of patients suffering from Alzheimer’s disease (AD) is rising in a similarly rapid manner. Elucidation of disease mechanisms and establishment of new strategies to prevent and/or treat and intervene AD are urgently required. Mutations in the PSEN1 gene are known to cause familial AD. In the current project, we generated multiple mouse lines that harbor different Psen1 mutations by genome editing technologies. Production pattern of amyloid-β (Aβ) in the brain was different from that in culture cell models in previous reports. By crossing the mutant Psen1 mice with next generation AD mouse model that was previously developed in our lab, we succeeded in generating new AD mouse model that precisely recapitulates the brain pathology in human AD patients.

Academic Significance and Societal Importance of the Research Achievements |
超高齢化社会を迎えている日本において、アルツハイマー病(AD)患者は増加の一途をたどっており、患者や介護者のウェルビーング、介護離職、医療費や介護費増大など様々な社会問題を引き起こしている。本研究課題では、疾患モデルの特徴を明らかにし、更に早期からヒトAD患者によく類似した病理を呈する優れたモデルを作製することに成功した。これらの成果は、今後のADの病態理解および新規治療法の確立に大きく貢献することが期待される。
