Outline of Research at the Start

炎症性腸疾患(IBD)は、難治性の慢性腸管炎症性疾患である。依然として根治術は存在せず、多くの分子標的療法が臨床応用されているものの、不十分な効果や、感染症をはじめとした副作用が依然として大きな問題である。本研究では、多数の分子を標的として細胞内シグナルを調整するmiRNAに着目し、IBDの病態に関与する腸管免疫細胞特異的な新規炎症惹起性パスウェイを同定し、新規IBD治療法の開発を目指す。

Outline of Final Research Achievements

Th17 cell, which is defined as the IL-17 producing T helper cell, has been reported to contribute to the pathogenesis of inflammatory bowel disease (IBD). Comprehensive analyses of global microRNA expression in haematopoietic cells identified miRNA-221/2, which is highly expressed in Th1 and Th17 cells involved in intestinal inflammation and poorly expressed in cells not involved in inflammation such as Naive T cells and regulatory T cells. In addition, we reported the regulatory mechanism of gene expression of miRNA-221/2 and their biological significance in intestinal inflammation.

Academic Significance and Societal Importance of the Research Achievements

炎症性腸疾患(IBD)は、難治性の慢性腸管炎症性疾患である。依然として根治術は存在せず、多くの分子標的療法が臨床応用されているものの、不十分な効果や、感染症をはじめとした副作用が依然として大きな問題である。本研究は、多数の分子を標的として細胞内シグナルを調整するmiRNAに着目し、腸管炎症T細胞特異的なmiRNA-221/2の発現制御機構と腸炎病態および腸管粘膜免疫における生物学的意義を明らかとするとともに、Th細胞サブセットの垣根を超えた炎症惹起性Th細胞全体を標的とする全く新しい治療アプローチの開発の基盤となりうる知見を報告した。
