Insights
Hepatitis C virus (HCV) infection affects millions globally. This review details various model systems for studying HCV, aiding research into treatments and vaccines.
Area of Science:
- Hepatology and Virology
Background:
- Hepatitis C virus (HCV) poses a significant global health challenge, with 170 million chronically infected individuals worldwide.
- Despite effective antiviral therapies, challenges remain, including treatment accessibility, drug resistance, and the absence of a protective vaccine.
Purpose of the Study:
- To provide a comprehensive overview of existing model systems for dissecting the Hepatitis C virus life cycle.
- To compare various assays and models used in Hepatitis C virus research, from basic science to translational applications.
Main Methods:
- Review of established noninfectious and infectious model systems for assessing HCV entry and replication.
- Analysis of cellular systems for host/pathogen interaction studies.
- Evaluation of in vivo model systems for basic and translational Hepatitis C virus research.
Main Results:
- A variety of model systems exist to study individual steps of the Hepatitis C virus life cycle.
- These systems encompass diverse approaches, including cell culture and animal models.
- Comparative data on the utility of different assays and models are presented.
Conclusions:
- Available model systems are crucial for advancing our understanding of Hepatitis C virus.
- Further research utilizing these models is essential to address remaining challenges in HCV treatment and prevention.
- The development and application of robust model systems are key to overcoming the global burden of Hepatitis C virus infection.
Abstract:
Hepatitis C virus is a major global health concern with 170 million people chronically infected. Despite the availability of potent antiviral agents targeting multiple HCV proteins and cure rates above 90%, global treatment availability, the likelihood of emerging drug-resistant viral variants and the unavailability of a protective vaccine underline the many unresolved questions remaining to be answered. Model systems allowing the dissection of individual HCV life cycle steps have previously been developed and span noninfectious and infectious means of assessing HCV entry and replication, multiple cellular systems enabling host/pathogen interaction studies as well as in vivo model systems for basic as well as translational HCV research. This review provides an overview of available systems and a comparative summary of assays and models.
