Hepatitis C virus and cellular stress response: implications to molecular pathogenesis of liver diseases

Area of Science:

• Hepatology
• Virology
• Cellular Biology

Background:

• Hepatitis C virus (HCV) infection is a major cause of chronic liver disease, affecting 3% of the global population.
• Current HCV therapies have limitations, necessitating a deeper understanding of disease mechanisms.
• HCV infection is linked to liver steatosis, cirrhosis, and hepatocellular carcinoma.

Purpose of the Study:

• To review cellular stress responses activated by HCV infection.
• To explore the link between HCV-induced cellular responses and liver disease pathogenesis.
• To identify potential therapeutic targets for HCV-associated chronic liver diseases.

Main Methods:

• Literature review of in vitro and in vivo studies on HCV infection.
• Analysis of emerging evidence on HCV-induced cellular stress pathways.
• Exploration of the relationship between cellular responses and disease pathogenicity.

Main Results:

• HCV infection induces significant cellular stress, including cell cycle arrest, apoptosis, ER stress/UPR, and autophagy.
• These stress responses may contribute to liver disease progression by affecting cell proliferation, lipid metabolism, and oncogenic pathways.
• The precise molecular mechanisms linking HCV-induced stress to chronic liver disease remain under investigation.

Conclusions:

• HCV infection activates diverse cellular stress responses that play a role in chronic liver disease.
• Further research into these mechanisms is essential for discovering novel therapeutic targets.
• A comprehensive understanding of HCV-mediated disease progression can guide new intervention strategies.
