Outline of Final Research Achievements

There are several mouse models which can reproduce Alzheimer's disease (AD) pathology, however, some models need almost one year to observe AD pathology in brain. We previously found that aging attenuates dynein-mediated retrograde transport in brain, and dynein dysfunction causes age-dependent accumulation of beta-amyloid protein (Abeta). In the present study, we aimed to establish a brand-new transgenic mouse which reproduces age-related dynein dysfunction to induce Abeta pathology.
Although we succeeded to establish triple transgenic mouse (SynI-Cre/LSL-Cas9/Dynein-gRNA), we did not enough gene expression to induce dynein knockout in mouse brain. Then we changed our plan to establish whole body knockout mouse by using CRISPER/Cas9 system. Since dynein knockout is fatal, we selected dynein transport-related proteins, which can also affect Abeta accumulation, as the target for knockout. Fortunately, we established a new dynein transport-related protein knockout mouse line.

Academic Significance and Societal Importance of the Research Achievements

アルツハイマー病のモデルマウスはこれまでにも数多く作成されているが、病変の形成が認められるまで1年以上の飼育が必要になるなど、病態解析に用いる場合はもちろん、薬剤の評価系としても少なからず問題が存在する。そこで本研究では、これまでの研究成果により明らかとなった、アルツハイマー病変蛋白質の蓄積を引き起こす脳神経系の老年性変化を人為的に促進するマウスを開発し、既存のモデルマウスと交配させることで病変形成をより加速化させることを目的とするものである。
本研究の成果により、アルツハイマー病研究をより効率的に進めることが可能となることが期待できる。
