Hepatitis C virus (HCV) infection affects millions globally, often leading to severe liver disease. This review explores HCV

Area of Science:

  • Hepatology
  • Virology
  • Immunology

Background:

  • Hepatitis C virus (HCV) infection is a significant global public health concern, affecting approximately 350 million individuals worldwide.
  • Chronic HCV infection frequently progresses to severe liver disease and cancer.
  • Current antiviral therapies, primarily interferon (IFN) and ribavirin, achieve sustained viral eradication in less than 50% of treated patients.

Purpose of the Study:

  • To review the pathogenetic mechanisms of HCV infection, focusing on viral protein interactions with host cellular signaling pathways.
  • To discuss viral strategies for persistence and evasion of antiviral therapy.
  • To highlight the challenges in understanding HCV biology due to the lack of reliable in vitro and in vivo models.

Main Methods:

Related Experiment Videos

  • Review of existing literature and experimental data on HCV pathogenesis.
  • Focus on the roles of HCV core, NS3, and NS5A proteins.
  • Analysis of host cellular signaling transduction pathways involved in cell growth and viability.

    • Main Results:

    • HCV proteins (core, NS3, NS5A) interact with host signaling pathways regulating cell growth and viability.
    • The virus employs specific strategies to persist within the host.
    • HCV has developed mechanisms to escape antiviral therapies.

    Conclusions:

    • Understanding HCV pathogenesis requires further investigation into viral-host interactions.
    • Development of improved in vitro and in vivo models is crucial for advancing HCV research.
    • Elucidating viral persistence and immune evasion strategies may lead to more effective therapies.
