How hepatitis C adapts to other species to help develop vaccines

Genetic Viral and Host Adaptations to Breach Species Barriers of HCV

NIH-funded research Princeton University · NIH-11469762

Researchers are making a mouse-friendly version of hepatitis C so scientists can better test vaccines and understand the virus for people living with or at risk of hepatitis C.

What this research studies

This project aims to create an immunocompetent mouse model of hepatitis C by using a newly identified murine-adapted virus called Mad18. Scientists will study the viral and host genetic changes that let HCV overcome species barriers using primary murine hepatocytes and whole-animal experiments. The model will be used to explore how chronic infection and liver disease develop and to try vaccine approaches in a system that more closely mimics human immune responses. The team combines molecular biology, virology, and immunology methods to map those barriers and test whether vaccine candidates trigger protective immunity.

Who could benefit from this research

Good fit: Although the current work is preclinical, future related trials would recruit adults with chronic hepatitis C or people at high risk of HCV exposure for vaccine testing.

Not a fit: People seeking immediate treatment for hepatitis C or those not at risk of HCV exposure should not expect direct or near-term benefit from this animal-model research.

Why it matters

Potential benefit: If successful, this work could speed development of preventive hepatitis C vaccines and improve tools to reduce new infections and long-term liver damage.

How similar studies have performed: Direct-acting antiviral drugs already cure most hepatitis C infections, but creating a robust small-animal model is relatively novel and builds on recent successes with murine-adapted viral variants.
