Outline of Research at the Start

近年多発性硬化症の疾患感受性遺伝子が内皮細胞に局在していると指摘されており,血液脳関門(blood-brain barrier:BBB)構成内皮細胞は新規の治療標的を発見する興味深い候補である.ただし,患者BBBサンプルのアクセスが困難であるためにBBBの研究は進んでいない.本研究では,MS患者iPS細胞由来BBBモデルを使用することで,MS患者のBBBに遺伝的な異常が存在するかを明らかにし,BBB破綻の責任遺伝子を同定することを目的としている.BBB破綻の標的分子は,これまでの免疫細胞を標的とした治療とは全く異なる,BBB安定化をターゲットとした新規MS治療薬開発につながる.

Outline of Final Research Achievements

In multiple sclerosis (MS), the breakdown of the blood-brain barrier (BBB) is implicated in the pathogenesis, but research progress has been hindered by the difficulty in accessing patient samples. This study demonstrated the direct involvement of BBB breakdown in MS pathogenesis by establishing patient-derived BBB models using induced pluripotent stem cells (iPSCs). Additionally, candidate molecules involved in BBB breakdown in MS were identified, and their functional analysis was conducted.

Academic Significance and Societal Importance of the Research Achievements

BBB破綻が直接的にMS病態に関わることを示した本研究成果は,これまでの免疫細胞を主体としてきたMSの病態理解とは全く別の,BBB破綻を中心とした病態解明,創薬標的の確立につながる.また,患者のBBBをin vitroに再現できることから,患者由来モデルはBBBを強固にする治療標的のスクリーニングとしての活用が期待される.BBBの破綻はMSのみならず,認知症をはじめとした数多くの神経疾患で共通して観察される現象であることから,その学術的・社会的意義は極めて大きい.
