Hepatitis B Virus Replication Machinery (HBV Replication Machinery)

Target
HBV Replication Machinery
Molecular classification
Viral replication complex, Multi-component system
01

Overview

The Hepatitis B virus (HBV) replication machinery refers to the collection of viral and host components responsible for the replication of HBV within infected hepatocytes. This machinery is central to the HBV life cycle, enabling the production of new viral genomes and particles. Key components include the HBV polymerase, pregenomic RNA (pgRNA), core protein, and cccDNA. It enables persistent infection, high-level virion production, and genetic diversity. Current therapies target reverse transcriptase activity but do not eliminate cccDNA.
