Project Description

TP17: Contribution of innate immune responses to persistence versus clearance of hepatitis C and hepatitis A virus infections

Hepatitis C virus (HCV) and hepatitis A virus (HAV) share very similar replication strategies. However, HAV infections are always cleared whereas HCV establishes persistence in most cases. The overall aim of this project is to achieve a comprehensive understanding of the mechanisms involved in inducing and counteracting innate immune responses by HAV and HCV, mainly focusing on toll-like receptor 3. Our results will thereby define the key factors responsible for the balanced induction of innate immunity finally determining the establishment of persistent infection of the liver.
