Caroline GOUJON has been awarded an ERC StG 2017 for the ANTIViR project (Mechanisms of interferon-induced antiviral restriction and signaling)

Research project

Caroline Goujon’s project aims at providing a better understanding of the interferon-induced, natural defences against human pathogenic viruses. Interferon is produced by infected cells following the detection of pathogenic viruses and bacteria and is the first line of defense against infection. Interferon induces several hundred genes both in infected and bystander cells and induced an antiviral state. The ANTIViR project aims at characterizing the effectors of this antiviral state and the mechanisms of the antiviral restriction. HIV-1 and influenza A virus are both sensitive to the interferon-induced antiviral state in human cells, partly because of the activity of the Mx GTPases (MX1 and MX2). The project aims at understanding the mechanism of action of the Mx proteins and at identifying and characterizing new actors of the antiviral state against these human pathogenic viruses, using powerful approaches such as whole-genome scale CRISPR/Cas9 genetic screens.
