抽象的

慢性乙型肝炎病毒 (HBV) 感染是全球肝脏相关发病率和死亡率的主要原因。 HBV-DNA 整合到人类基因组中被认为是 HBV 感染早期阶段经常发生的事件,并表征了 HBV 自然史的整个过程。精细分子生物学技术的发展揭示了 HBV-DNA 整合到人类基因组中的功能意义,包括其在 HBV 相关发病机制进展中的作用,以及在引发促癌机制的建立、促进肝细胞癌。本综述对当前关于 HBV-DNA 整合的知识体系进行了更新和全面的概述,重点关注 HBV-DNA 整合的分子机制及其在 HBV 感染自然史的不同阶段中的发生。此外,我们在这里讨论了 HBV 整合作为 HBV 相关发病机制的生物标志物的主要临床意义,特别是在肝癌发生方面,以及整合如何成为目前和新型抗病毒疗法实现 HBV 治愈的障碍。总体而言,对 HBV 整合的机制和功能进行更精细的了解至关重要,因为它可能为特设诊断工具的设计提供信息,这些工具能够揭示干扰相关细胞内途径的 HBV 整合事件,并用于确定直接针对改变的新治疗策略与 HBV 整合有关。

Abstract

Chronic infection with Hepatitis B Virus (HBV) is a major cause of liver-related morbidity and mortality worldwide. HBV-DNA integration into the human genome is recognized as a frequent event occurring during the early phases of HBV infection and characterizing the entire course of HBV natural history. The development of refined molecular biology technologies sheds new light on the functional implications of HBV-DNA integration into the human genome, including its role in the progression of HBV-related pathogenesis and in triggering the establishment of pro-oncogenic mechanisms, promoting the development of hepatocellular carcinoma. The present review provides an updated and comprehensive overview of the current body of knowledge on HBV-DNA integration, focusing on the molecular mechanisms underlying HBV-DNA integration and its occurrence throughout the different phases characterizing the natural history of HBV infection. Furthermore, here we discuss the main clinical implications of HBV integration as a biomarker of HBV-related pathogenesis, particularly in reference to hepatocarcinogenesis, and how integration may act as a barrier to the achievement of HBV cure with current and novel antiviral therapies. Overall, a more refined insight into the mechanisms and functionality of HBV integration is paramount, since it can potentially inform the design of ad hoc diagnostic tools with the ability to reveal HBV integration events perturbating relevant intracellular pathways and for identifying novel therapeutic strategies targeting alterations directly related to HBV integration.

Keywords: HBV biomarkers; HBV cure; HBV-DNA integration; chronic HBV infection; hepatocellular carcinoma.
