Insights

Host genetics influence Hepatitis C Virus (HCV) control. Genetic variations in interleukin 28B (IL28B) are key predictors of spontaneous and treatment-induced HCV recovery, suggesting IL28B

Area of Science:

  • Immunogenetics
  • Virology
  • Hepatology

Background:

  • Hepatitis C Virus (HCV) infection is cleared spontaneously in 30% of cases and treatment cures 40% of chronic infections.
  • Host genetic factors are suspected to play a crucial role in controlling HCV infection outcomes.
  • Understanding these genetic determinants is vital for improving HCV management.

Purpose of the Study:

  • To review genome-wide association studies (GWAS) and candidate gene studies on host genetic variation in HCV control.
  • To identify key genetic factors influencing spontaneous and treatment-induced HCV clearance.
  • To explore the implications of these findings for future HCV treatment strategies.

Main Methods:

  • Systematic review of four genome-wide association studies (GWAS).
  • Inclusion of two large candidate gene studies assessing host genetic variation.
  • Analysis focused on genetic predictors of natural and treatment-induced HCV control.

Main Results:

  • Genetic variations in interleukin 28B (IL28B) consistently emerged as the strongest predictor of HCV control.
  • Single nucleotide polymorphisms (SNPs) in IL28B significantly predicted both spontaneous and treatment-induced HCV recovery.
  • IL28B encodes interferon-lambda (IFN-λ), a type III interferon with antiviral properties.

Conclusions:

  • Strong genetic evidence supports the role of interferon-lambda (IFN-λ) in controlling HCV infection, both naturally and post-treatment.
  • IL28B genetic variations offer potential for personalized HCV treatment strategies.
  • Further research into IFN-λ is warranted for developing novel therapies for chronic hepatitis C.

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. The...

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 of food...
Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Viruses with RNA Genomes01:29

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...
Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
