Insights

Hepatitis C virus (HCV) chronic infection leads to liver cirrhosis and cancer. This review explores host proteins involved in HCV replication, offering insights for new chronic hepatitis C therapeutics.

Area of Science:

  • Hepatology
  • Virology
  • Molecular Biology

Background:

  • Hepatitis C virus (HCV) causes blood-borne hepatitis, often leading to chronic liver disease, cirrhosis, and hepatocellular carcinoma.
  • Understanding HCV's life cycle, including entry, replication, and pathogenesis, is crucial for developing effective treatments.
  • Recent advancements in HCV research include pseudotype viruses, in vitro replication systems, and autonomous RNA replication systems.

Purpose of the Study:

  • To review current knowledge on host proteins that participate in Hepatitis C virus replication.
  • To explore potential novel therapeutic interventions for chronic hepatitis C by targeting host-viral protein interactions.

Main Methods:

  • Utilizing pseudotype viruses to identify viral receptor candidates.
  • Employing an in vitro replication system of the HCV JFH1 strain.
  • Investigating autonomous RNA replication systems based on artificial viral genomes.

Main Results:

  • HCV replicates within an intracellular complex involving both viral and host proteins.
  • Specific host proteins are essential for HCV replication and assembly.
  • Inhibitors targeting host factors, such as cyclosporin A and sphingolipid synthesis inhibitors, demonstrate efficacy in blocking HCV replication.

Conclusions:

  • Host proteins play a critical role in the Hepatitis C virus life cycle.
  • Targeting the interplay between host and viral proteins presents a promising strategy for developing new anti-HCV therapeutics.
  • Further research into host-viral interactions could lead to novel treatments 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...
Inhibitors Of Virion Release01:25

Inhibitors Of Virion Release

Viral replication and dissemination rely on efficient mechanisms for host cell entry, genome replication, assembly, and release. Influenza viruses, such as types A and B, are negative-sense single-stranded RNA viruses with a segmented genome, that depend on two critical surface glycoproteins to carry out these processes: hemagglutinin (HA) and neuraminidase (NA). HA initiates infection by binding to sialic acid residues on the surface of host epithelial cells, facilitating receptor-mediated...
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...
Retroviruses02:33

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
Inhibitors of Virion Maturation and Assembly01:19

Inhibitors of Virion Maturation and Assembly

As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
