慢性B型肝炎病毒感染是肝硬化和肝细胞癌的重要危险因素。HBx蛋白是病毒复制所必需的,但缺乏强大的感染模型阻碍了我们对HBx功能的理解,这些功能可以用于抗病毒目的。我们简要回顾了HBx的三个特性:它与DDB1的结合以及它对细胞存活和代谢的调节,以说明单个病毒蛋白如何在细胞中产生多种作用。我们认为,不同的功能HBx是必要的,这取决于在慢性病毒感染过程中遇到的肝细胞环境的变化,这些功能可能作为抑制B型肝炎病毒复制和相关疾病的发展的新的治疗靶点。
Chronic hepatitis B virus infection is a significant risk factor for cirrhosis and hepatocellular carcinoma. The HBx protein is required for virus replication, but the lack of robust infection models has hindered our understanding of HBx functions that could be targeted for antiviral purposes. We briefly review three properties of HBx: its binding to DDB1 and its regulation of cell survival and metabolism, to illustrate how a single viral protein can have multiple effects in a cell. We propose that different functions of HBx are needed, depending on the changing hepatocyte environment encountered during a chronic virus infection, and that these functions might serve as novel therapeutic targets for inhibiting hepatitis B virus replication and the development of associated diseases.
