Outline of Research at the Start

脳アミロイド血管症は血管壁に主としてAβ40が蓄積し血管壁が脆弱となり、しばしば皮質の大出血を起こす。最近では脳アミロイド血管症関連の脳炎症状態も報告されているがその機序は解明されていない。高齢化とともに脳アミロイド血管症を発症する症例が増えており治療法も開発されていない。またCAAを3次元的にin vitroで作成された報告は未だにない。
我々のこれまでの研究によりCAAのモデル血管をin vitroで作成したので、血管壁のAβ沈着を除去できる様々な治療法の開発を目的とする。血管壁にAβ沈着するメカニズムも解明できた場合には、予防的な治療法の開発も着手する。

Outline of Final Research Achievements

We established a scaffold-free system for assembling cell constructs using an automated Bio-3D printer with the Kenzan method. We aim to create an in vitro model of CAA using this method, and analyze the pathophysiology and mechanisms that causes CAA. We assemble multicellular spheroids composed of normal human dermal fibroblasts, smooths muscle cell and human umbilical vein endothelial cell to construct tubular vessels and cultured in the presence of Abeta 40 peptides. Immunostaining against Abeta 40 showed the amyloid deposition on the outer layer of vessel wall at the site that matches collagen IV positive extracellular matrix, but not coincident with SMA. The tensile strength of the tubular vessels revealed decreased elasticity and strength in the presence of Abeta 40. CAA in vitro model showed the different stainability of collagen, SMA and CD31, and decreased elasticity and strength of tubular vessels compared to control, suggesting vessel fragility.

Academic Significance and Societal Importance of the Research Achievements

脳アミロイド血管症の病態機序や治療法は未だ解明されていない。この研究により脳アミロイド血管症のモデル血管をin vitroで作成することにより、血管壁のAβ沈着を除去できる様々な治療法の開発に応用できると考えられる。また血管壁にAβ沈着するメカニズムも解明できた場合には、予防的な治療法の開発にもつながると考えられる。
