Outline of Research at the Start

本研究課題では、高分子集合体(ナノマシン)を基盤技術とし、高分子化学、材料科学、蛋白質工学的観点からさらに洗練し、従来の薬剤を疾患部位に送り届けるDDSではなく、既存技術では着想もしないBBBを効率的に通過し、脳分子を回収、さらには血液中に帰還することで、脳分子情報を知らせるナノマシンを構築し、中枢神経系疾患の革新的診断法へと展開し、脳内外の物質移動研究に新たな学術的視点をもたらすことを目的とする。また脳分子と脳機能・疾患との関連を精査する分子脳病態班と、独自の高感度分析技術を駆使したマルチオミックス解析により微量の脳内成分の同定を行う極限検出班と連携し、脳分子探査の研究基盤構築に貢献する。

Outline of Final Research Achievements

In this study, we developed nanomachines capable of passing the blood-brain barrier to collect brain molecules and transport them back into the bloodstream. Specifically, we investigated (1) the development of nanomachines that undergo structural changes in response to the brain environment to collect brain molecules, and (2) the development of nanomachines that return from the brain into the bloodstream. First, we synthesized novel block copolymers with the desired functions. Regarding (1), we confirmed that polymer micelles with a diameter of approximately 30 nm in the blood environment transform into polymer vesicles with a diameter of approximately 150 nm in the brain environment. We also confirmed that these structural changes enable the sampling of neurotransmitters. As for (2), we succeeded in developing nanomachines capable of moving the micelles from the brain into the bloodstream by incorporating Fc fragments on their surface.

Academic Significance and Societal Importance of the Research Achievements

「脳内で集合体の構造変化を惹起」することで「脳分子を回収」し、さらに「血液中に帰還する」ことで早期診断へ展開する「はやぶさ型ナノマシン」については、脳へ多量の高分子集合体を送達可能な申請者の技術なしでは着想もしない独創的な研究であり、脳内外の物質移動研究に新たな学術的視点をもたらすことが想定される。幅広い精神神経疾患や脳炎など広範な疾患についても大きく貢献することが確信される。また高分子/材料設計の観点からも、生体適合性・標的指向性・環境応答性という異なる機能を空間的に制御された形で構造内部に配置する仕掛けを創り込むなど、独創性に秀でた生体材料設計プロセスを当該分野にもたらす意義を有する。
