    Insights

    Replicative hepatitis B virus (HBV) forms in the liver are linked to disease activity. Active HBV replication patterns were found in most hepatitis B e antigen-positive patients and some negative patients with advanced liver disease.

    Area of Science:

    • Hepatology
    • Virology
    • Molecular Biology

    Background:

    • The replicative forms of hepatitis B virus (HBV) in the liver during chronic liver disease remain poorly understood.
    • Investigating HBV DNA and its alterations in liver tissue is crucial for understanding disease progression.

    Purpose of the Study:

    • To analyze HBV DNA and its changes after endonuclease digestion in liver tissues of patients with chronic liver disease.
    • To correlate HBV replicative forms with clinical and serological markers.

    Main Methods:

    • Analysis of HBV DNA and endonuclease digestion patterns in liver tissues from 64 patients.
    • Southern blot analysis to resolve episomal replicative forms of HBV.

    Main Results:

    • An "active" HBV replication pattern was observed in 95% of hepatitis B e antigen-positive patients.
    • This active pattern was also present in 19% of hepatitis B e antigen-negative patients with high ALT levels and advanced liver disease.
    • An "inactive" episomal viral DNA form was found in patients with mild liver disease and low ALT levels.

    Conclusions:

    • Episomal replicative forms of HBV can be detected in liver tissue and appear to have clinical significance.
    • The presence and form of HBV DNA in the liver correlate with disease activity and severity.

    Viral Mutations

    A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

    Restarting Stalled Replication Forks

    DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart,...

    Viruses with RNA Genomes

    RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

    Hepatitis

    Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

    Inhibitors of Viral Protein Synthesis01:30

    Inhibitors of Viral Protein Synthesis

    Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

    Viral Hepatitis I: Introduction

    Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion...
