溶质载体家族肝脏细胞表达谱及其在药物性肝损伤中的分子机制与靶向策略

Hepatic Expression Profiles of Solute Carrier Family and Their Molecular Mechanisms and Targeted Strategies in Drug-Induced Liver Injury

  • 摘要: 药物性肝损伤(drug-induced liver injury,DILI)是造成临床患者肝损伤的重要原因,也是一种常见的不良反应,特别是在老年人和慢性肝病患者中。研究认为,溶质载体(solute carrier,SLC)转运体在药物性肝损伤的发病过程中呈现“细胞特异性”的表达,其转运底物不仅包括药物,还包括胆汁酸、氨基酸、乳酸等内源性代谢物,提示该类转运体在DILI进展中发挥关键作用。因此,本文阐述SLC转运体在肝细胞、库普弗细胞(Kupffer cells,KCs)、肝星状细胞(Hepatic Stellate Cells,HSCs)、胆管细胞等主要肝脏细胞类型的表达谱及其在DILI发病过程中的分子机制,阐述了SLC在不同类型细胞的表达与DILI发生的相关性,同时结合SLC的保护剂或抑制剂等相关治疗策略为后续治疗和研究提供理论参考。

     

    Abstract: Drug-induced liver injury (DILI) is a major cause of clinical liver injury and a common adverse drug reaction, especially in the elderly and patients with chronic liver disease. Previous studies have suggested that solute carrier (SLC) transporters exhibit “cell-specific” expression during the pathogenesis of DILI, indicating a critical role of SLC in the progression of DILI. Therefore, this review focuses on the molecular mechanisms of SLC in DILI across major hepatic cell types, including hepatocytes, Kupffer cells (KCs), hepatic stellate cells (HSCs), and cholangiocytes. The correlation between SLC expression in different cell populations and the occurrence of DILI is elaborated. In addition, relevant therapeutic strategies involving SLC protectors or inhibitors are summarized to provide theoretical references for further research and clinical treatment of DILI.
