Insights
Hepatitis C virus (HCV) infection causes liver fibrosis. This review examines changes in hepatic stellate cells (HSCs) during HCV infection, proposing them as potential diagnostic markers for disease progression.
Area of Science:
- Hepatology
- Virology
- Cell Biology
Background:
- Hepatitis C virus (HCV) infection is a major global health concern, leading to cirrhosis and hepatocellular carcinoma.
- Liver fibrosis, a progressive condition, is a key driver of end-stage liver disease in chronic hepatitis C (CHC).
- Hepatic stellate cells (HSCs) are central to liver fibrosis development, activating into myofibroblasts during chronic liver injury.
Purpose of the Study:
- To review characteristic changes in HSCs during HCV infection.
- To identify potential cellular and molecular diagnostic markers for CHC progression.
- To enhance timely diagnosis and disease management of HCV-related liver fibrosis.
Main Methods:
- Review of scientific literature focusing on HSCs in HCV infection.
- Analysis of HSC surface markers, cytokine production, activation states, cell function, and morphological alterations.
- Synthesis of data to identify diagnostic potential at cellular and molecular levels.
Main Results:
- HSCs undergo significant changes in surface markers, cytokine profiles, and activation status during HCV infection.
- These alterations in HSCs correlate with the progression of liver fibrosis.
- HSCs present a promising avenue for developing novel diagnostic markers for CHC.
Conclusions:
- Understanding HSC behavior during HCV infection is crucial for diagnosing and monitoring liver fibrosis.
- HSCs offer potential as both cellular and molecular biomarkers for CHC disease progression.
- Further research into HSC-specific markers could significantly improve the management of HCV infection.
Abstract:
Hepatitis C virus (HCV) infection is a global public health problem. Cirrhosis and hepatocellular carcinoma are the main causes of death in patients with chronic hepatitis C (CHC) infection. Liver fibrosis is an important cause of cirrhosis and end‑stage liver disease after CHC infection. Along with the course of infection, liver fibrosis exhibits a progressive exacerbation. Hepatic stellate cells (HSCs) are involved in both physiological and pathological processes of the liver. During the chronic liver injury process, the activated HSCs transform into myofibroblasts, which are important cells in the development of liver fibrosis. At present, HCV infection still lacks specific markers for the accurate detection of the disease condition and progression. Therefore, the present review focused on HSCs, which are closely related to HCV‑infected liver fibrosis, and analyzed the changes in the HSCs, including their surface‑specific markers, cytokine production, activation, cell function and morphological structure. The present review aimed to propose novel diagnostic markers, at both the cellular and molecular level, which would be of great significance for the timely diagnosis of the disease. According to this aim, the characteristic changes of HSCs during HCV infection were reviewed in the present article.
