摘要: 药物性肝损伤(DILI)机制复杂,涉及多种途径协同促进并互为因果,其中免疫反应在致病机制中扮演重要角色。在遗传背景因素下,药物活性代谢产物、药物-分子复合物、危险信号分子或可作为DILI发生的免疫反应触发因子,激活药物抗原性超敏反应机制、P-i假说和固有免疫危险信号机制。使肝脏出现固有免疫、适应性免疫级联反应,导致肝脏固有免疫耐受状态失衡,进而造成肝脏组织的免疫炎症性损伤。本文主要阐述DILI的免疫学发生机制,以期为DILI治疗靶点的研发及规避用药不良反应等提供新的思路。

Abstract: Drug-induced liver injury (DILI) has a complex mechanism involving various pathways with a synergistic effect on each other and a causal relationship with each other, among which immune response plays an important role in the pathogenesis of DILI. In the context of genetic background, drug active metabolites, drug-molecule complexes, and danger signal molecules may be used as the trigger factors for immune response in DILI, activating the mechanism of drug antigenic hypersensitivity, P-i hypothesis, and danger signal mechanism in innate immunity. The cascade reaction of innate immunity and adaptive immunity leads to the imbalance of the innate immune tolerance of the liver and thus causes immunoinflammatory injury of liver tissue. This article mainly elaborates on the immunological mechanism of DILI, in order to provide new ideas for the research and development of therapeutic targets for DILI and the methods for avoiding adverse drug reactions.-
