Outline of Final Research Achievements

In the development of the Enhanced Drug-Repositioning Delivery System, HA-coated micelles were found to be a promising candidate as a drug delivery vehicle in liver fibrosis, indicating the potential for clinical application. In the development of the Enhanced Drug-Repositioning Delivery System, HA-coated micelles were found to be a promising candidate as a drug delivery vehicle in liver fibrosis, indicating their potential for clinical application. Furthermore, we demonstrated that the control of leaky gut contributes to the improvement of liver pathology, including liver fibrosis, by using a drug that is already in clinical use as a dual cascade blocker of leaky gut.

Academic Significance and Societal Importance of the Research Achievements

本研究からHAコーティングミセルは、肝線維症におけるドラッグデリバリービークルとして有望な候補であることが明らかとなり臨床応用の可能性が示された。さらに、Leaky gut の Dual cascade blockとして肝に流入した内因性エンドトキシン活性化シグナルを阻害することにより肝硬変の病態進行を抑制するために既に臨床で使用されている薬剤賀有効であることを見いだした。これらの成果により臨床応用を見据えたDrug Repositioningによる新規治療法基礎的データが得られた。
