乙型肝炎的分子生物学涉及对病毒复制和基因表达的研究,即对病毒DNA、RNA和蛋白质结构及其功能的研究。近年来,分子生物学技术已大量运用于对HBV的研究,使我们对病毒持续性感染、慢性肝病和肝细胞癌(HCC)有了更多的了解,进一步确证了HBVD-NA的整合和HCC之间存在着的关系。尤其是近几年在土拨鼠、地松鼠和北京鸭中发现了一组在结构和生物学性质上与HBV相似的动物病毒,统称为Hepadra Virus(嗜肝病毒)。
Molecular biology of hepatitis B involves the study of viral replication and gene expression, ie the study of the structure and function of viral DNA, RNA and proteins. In recent years, molecular biology techniques have been extensively used in the study of HBV, giving us a better understanding of persistent virus infection, chronic liver disease and hepatocellular carcinoma (HCC), further confirming the integration of HBVD-NA and HCC There is a relationship between. In recent years, in particular, a group of animal viruses that are structurally and biologically similar to HBV have been found in groundhog, ground squirrel and Beijing duck, collectively known as Hepadra Virus.
