Scientific summary

Hepatitis C virus (HCV) is the only virus that is known to perturb hepatic glucose and lipid metabolism with important patho-physiological consequences that predispose towards the development of liver cancer. Chronic carriers often develop steatosis, insulin resistance and type 2 diabetes. HCV seems to rely on these modifications of the liver metabolic microenvironment to replicate efficiently. Indeed, some HCV proteins have been shown to interfere directly with many factors of the lipogenic and glycolytic pathways. We study HCV-induced changes in glucose-signaling and –metabolism, ask whether these changes are a prerequisite for HCV replication / assembly and analyse their pathological consequences.
The targeted modulation of cellular factors or pathways that we have identified to be necessary and beneficial for HCV production will allow us to develop novel therapeutic targets and on the long term to develop novel in vitro and in vivo infection systems for HCV, which will be critical to understand the pathogenesis of HCV infection and its role in hepatocarcinogenesis.
In particular, the following objectives are being addressed: 1) HCV-induced changes to the cellular glucose & lipid metabolism; 2) Development of more relevant cellular system with physiological metabolism for studying HCV replication and assembly/morphogenesis; 3) Development of innovative anti-HCV drugs; 4) Validation of the new concepts by experiments performed on clinical samples.
