Outline of Research at the Start

本研究の目的は、不死化細胞ミニブレイン(Immortalized cell-based mini-Brain, ImBrain)を創成すること、さらに、高分子の脳移行解析や中枢神経系に対する薬物の毒性解析におけるImBrainの有用性・実装性を実証することである。ImBrainは、薬物脳送達技術開発や薬物のヒト中枢毒性発現の理解・評価を可能とするほか、幅広い中枢創薬研究に応用できる。したがって本研究で創成するImBrainは、中枢薬開発の成功率の向上と革新的新薬をもたらす基盤技術となることが大いに期待される。

Outline of Final Research Achievements

We report on the development of a human conditionally immortalized cell-based multicellular spheroidal blood brain barrier (hiMCS-BBB) model. After being seeded into non-attachment culture wells, HASTR/ci35 and HBPC/ci37 cells self-assemble to form a spheroid core that is then covered with an outer monolayer of HBMEC/ci18 cells. hiMCS-BBB models exhibit physical, as well as biological, barrier functions. Furthermore, hiMCS-BBB models show receptor-mediated transcytosis functions at the levels enough to evaluate BBB permeability of antibodies. In addition, tumor necrosis factor-alpha treatment elicited an inflammatory response in HBMEC/ci18 cells. Therefore, hiMCS-BBB models can be expected to provide a useful and highly accessible experimental platform for accelerating various drug development studies, including development of brain drug delivery carriers as well as toxicological evaluations.

Academic Significance and Societal Importance of the Research Achievements

本研究では、3種のヒト不死化細胞を階層的に組み合わせることにより、新たなスフェロイド型BBBモデルを確立した。これまでに全てヒト不死化細胞から成るスフェロイド型BBBモデルの報告はなく、世界でも初めての成果となる。本モデルは、不死化細胞の汎用性と生体模倣による高機能性を兼ね備えており、高分子薬物のBBB透過性評価や種々の薬物に対するBBB障害評価を、迅速・経済的に、かつ高い精度で行うことを可能とすると期待される。本モデルが標準評価系として産・学で広く活用されれば、新たな薬物脳送達技術創出および薬物のヒト中枢毒性の的確な予測評価法の確立につながると期待される。
