Outline of Final Research Achievements

We examined novel chemicals for fluroin MRI to detect senile plaques, neurofibrillary tangles and Lewy bodies in mouse brain. We synthesized a novel chemical, named Shiga-Y25. We injected Shiga-Y25 into a tail vein of APP/PS1 mouse. Using 7 Tesla MRI, SHiga-Y25 successfully revealed senile plaques in the mouse brain. We also synthesized a novel chemical, named Shiga-Y35. We injected Shiga-Y35 into a tail vein of rTg4510 mouse. Using 7 Tesla MRI, Shiga-Y35 successfully detected neurofibrillary tangles in the mouse brain. We could not find chemicals that specifically bind to alpha-synuclein aggregations.

Academic Significance and Societal Importance of the Research Achievements

本研究の最大の特色は、最先端のフッ素MR画像技術を駆使しアルツハイマー病、タウオパチー、パーキンソン病など、神経難病のMR画像診断薬を開発する点にある。その結果、アミロイドイメージング試薬としてShiga-x25、タウイメージング試薬としてShiga-X35を新規合成した。現在、神経難病の画像診断としては、PETによるアミロイドイメージング法が使われている。しかしながら、MR画像法は、PETに比べ放射性同位体を使わない、くり返し測定が可能、サイクロトロンのような高価な施設がいらないなど利点が多いため、将来的にPET診断法を補う(あるいは置き換わる)画像診断法になる可能性がある。
