Hepatitis virus particles (HVP)

Hepatitis virus particles refer to the complete infectious virions of the various viruses that cause inflammation of the liver, including Hepatitis A, B, C, D, and E. These particles consist of a viral genome (DNA or RNA) encased in a protein capsid, and in some cases, a lipid envelope derived from the host cell membrane. While the term is used to describe the infectious agent, it is considered an incorrect or overly broad therapeutic target because modern pharmacology targets specific viral proteins or enzymes—such as polymerases, proteases, or entry receptors—rather than the particle as a whole. Each hepatitis virus belongs to a different family (e.g., Hepadnaviridae for HBV, Flaviviridae for HCV) and employs distinct replication strategies, making a single 'particle' target scientifically imprecise. Effective treatments involve direct-acting antivirals that disrupt specific stages of the viral life cycle to reduce viral load and prevent chronic liver damage, cirrhosis, and hepatocellular carcinoma.

Drugs targeting hepatitis viruses typically inhibit specific viral enzymes such as RNA-dependent RNA polymerase, NS3/4A protease, or reverse transcriptase, rather than the whole virus particle itself.
