The interferon-induced antiviral state strongly inhibits viral replication in human cells, which means that our cells are capable of expressing powerful, natural antiviral inhibitors. Our team aims at understanding the mechanisms of the interferon-induced antiviral defences. Using powerful approaches (such as whole-genome CRISPR/Cas9 knock-out functional genetic screens), we aim at identifying new interferon-induced effectors, and then at characterizing their antiviral activity.
