Our projects
Interferon is produced by infected cells following the detection of pathogenic viruses and bacteria and is the first line of defence against infection. Interferon induces the expression of several hundred genes, names interferon-stimulated genes (ISGs) both in infected and neighbouring cells. The products of the ISGs, in turn, allow the establishment of a so-called antiviral state, which is able to prevent, or at least limit, viral replication. Most viruses, including influenza A virus, the Human Immunodeficiency Virus type 1 (HIV-1) and SARS-CoV-2, are highly sensitive to this antiviral state and unable to replicate efficiently in cells that have been pre-exposed to IFN.
The dynamin-like, high-molecular weight GTPases MX1 and MX2 play a significant role in the interferon-induced inhibition of viral replication. Human MX1 is a restriction factor of broad antiviral activity, able to inhibit a great diversity of RNA and DNA viruses at different stages of their life cycles. The activity of MX2 seems narrower and has so far been restricted to HIV-1 and some primate lentiviruses. MX2 prevents HIV-1 DNA nuclear import and integration. Both MX1 and MX2 seem to recognize and interact with key components of viral nucleoprotein complexes to prevent viral replication, however their detailed mechanisms of action remain to be understood. Other antiviral ISGs inhibiting HIV-1 and influenza A virus have been identified, however, our preliminary data show that additional genes remain to be identified. We have recently identified the short isoform of NCOA7, which is interferon-inducible, as a new antiviral factor preventing endocytosis-meditaed viral entry.
Our lab, named Interferon and antiviral restriction, which has been established in January 2015 at the CNRS institute of research on infection of Montpellier (IRIM, ex-CPBS), aims at identifying new cellular effectors of the antiviral state (using, among other approaches, whole-genome scale CRISPR/Cas9 screens) and at characterizing the molecular mechanisms involved in their antiviral activity.
Our main projects are the following:
- Understanding the antiviral activity of MX, NCOA7 and DDX42 proteins
- Physiological role and potential involvement in innate immune signalling of MX proteins
- Identification and characterization of new interferon-induced, antiviral effectors against HIV-1 and influenza A virus and other human pathogenic viruses, including SARS-CoV-2
- Identification of new genes regulating influenza virus and SARS-CoV-2 replication and search for new antiviral compounds
Since March 2020, we’ve also been studying SARS-CoV-2: we’re chacterizing the inhibitory effect of interferons, identifying cellular regulators of replication through whole-genome CRISPR screens and screening molecules to help identify new therapeutical avenues.

Team members
- Caroline Goujon – Team leader, INSERM tenure researcher (DR2)
Minibio: Caroline studied at at the Ecole Normale Supérieure (ENS) of Lyon. She did her Master’s and PhD in Dr Jean-Luc Darlix’s laboratory (Inserm U412/U758; Sept. 2002-Jan. 2008), under the supervision of Dr Andrea Cimarelli. She studied the restriction of HIV-1 infection in human dendritic cells and discovered for the first time that HIV-2/SIV Vpx was able to relieve this block. She then did a long postdoc in Prof. Michael Malim’s laboratory at King’s College London (Feb. 2008-Dec. 2014), where she was awarded a Marie Curie Intra-European Fellowship to study the host cell responses to HIV-1 infection. She became interested in the relationships between HIV-1 and the interferon system and characterized in depth the interferon-induced restriction of HIV-1 infection. She notably identified human MX2 as one of the major interferon-stimulated genes preventing HIV-1 infection. In 2014, she was awarded the Andy Kaplan prize and obtained both an INSERM researcher permanent position and an ATIP-Avenir grant to move back to France and start her own group. She has been working at the CNRS IRIM institute (which was formerly called CPBS) in Montpellier since January 2015. She has obtained in 2016 grants from Sidaction and the ANRS. She has been awarded an ERC Starting Grant in 2017 to study the mechanisms of interferon-induced antiviral restriction and mechanisms (ANTIViR project). In 2020, the lab obtained several fundings to work on SARS-CoV-2, MUSE (Montpellier university), from INSB, La fondation CNRS, the ANR-RACOVID, in order to identify and characterize anti-SARS-CoV-2 molecules, characterize the host cell responses to infection and identify the cellular regulators of viral replication through CRISPR screen. In 2020, C. Goujon has also been awarded a PRC ANR grant to study NCOA7’s mechanism of action and role in vivo, in collaboration with M. Blaise (IRIM) and M. Wencker (CIRI). In 2023, C. Goujon has been awarded an ERC CoG for the 2022 call (project InVIRium), to study the interactions between respiratory viruses and primary airway epithelia. This year she was promoted DR2 by Inserm.
- Olivier Moncorgé – Permanent Scientist CNRS (IR, from Dec. 2021) (former postdoc ATIP – ANRS – ERC Feb. 2015-Dec. 2020)
Minibio: After working as the molecular biology group leader in a French biotech company (Aptanomics SA, Lyon) and as an engineer (IE) on HIV-1 translation at the Ecole Normale Supérieure of Lyon, Olivier did his PhD and a 2-year postdoc in Prof. Wendy Barclay’s laboratory, at Imperial College London. Olivier worked on the molecular basis of host range restriction of avian influenza polymerases in mammalian hosts. During his first post-doc, Olivier was part of the European consortium ANTIFLU, aiming at identifying new inhibitors of influenza virus replication. Olivier also studied MX1 protein activity against influenza A virus. Olivier has joined the lab in Feb. 2015, thanks to the support of the ANRS (2-year fellowship obtained by C. Goujon in connection with the ATIP-Avenir grant, and 1-year fellowship renewal obtained by O. Moncorgé). Olivier has been working on the ERC ANTIViR and FluAttack projects since 2018 and 2019, respectively, and led all the influenza 1 virus-related topics of the lab. Thanks to his expertise on respiratory viruses, the team was able to rapidly start working on SARS-CoV-2 back in March 2020. Olivier notably led all the screening projects on SARS-CoV-2. His contract in the lab ended in Dec. 2020 and this year, Olivier was self-empoyed and a consultant on respiratory viruses. In 2021, he has obtained a permanant scientist position (IR) at the CNRS as a respiratory virus expert. Within IRIM and in parallel to his work in the team, Olivier has set up a technical platform for the study of respiratory viruses (webpage coming!). The purpose of this platform is to share Olivier’s expertise on respiratory viruses and in particular on influenza A and B viruses and on coronaviruses, to train people from the institute to their handling in BSL2 and BSL3 settings, to develop innovative viral reporter systems and to share them with the scientific community in the form of collaborations or services, in particular for antiviral molecule screening.

May 2021 : Second preprint from the team on SARS-CoV-2 ! In collaboration with John Doench (Broad Institute, USA), we have performed bidirectional genome-wide CRISPR screens in cells that are physiologically relevant and naturally express ACE2 and TMPRSS2. We have identified both new dependency factors and new inhibitors of SARS-CoV-2! Some of these genes do also regulate MERS-CoV (data obtained by Jean Dubuisson’s team, Institut Pasteur Lille), and seasonal human coronaviruses HCoV-NL63 and HCoV-229E.

In this study, we show a MDA-5 dependent interferon response in primary airway epithelia and model cell lines upon SARS-CoV-2 replication. However this interferon response, which arrives late, fails to control replication.
December 2020: The team was highlighted in the ‘Inserm magazine’ and on the inserm wbesite:

October 2020: the first two preprints from the team are online!
The first preprint describes the identification of DDX42 as a broad antiviral inhibitor. Boris Bonaventure, in the team, performed whole-genome CRISPR screens which led to the identification of DDX42 as an intrinsic inhibitor of HIV-1, in various cell lines and primary cells. DDX42 inhibits viral DNA accumulation and is in close proximity with Capsid in infected cells. DDX42 is also capable of inhibiting retrotranspoition of Line-1 and infection with different retroviruses. Finally, we reveal that DDX42 is also a potent inhibitor of other pathogenic viruses, including SARS-CoV-2!

All the team members participated in this work as well as Laurence Briant and Eric Bernard from IRIM (work on CHIKV) as well as Nathalie Gros from CEMIPAI (work on ZIKV). The library preparation and deep sequencing analysis was done by Hugues Parrinello and Stéphanie Rialle from Montpellier GenomiX.
In the second preprint, we have explored the host cell responses to SARS-CoV-2 both in primary human airway epithelia and in model cell lines. We observed a potent interferon induction, mainly due to sensing by MDA-5, but unable to control replication.

Opened: 2 Postdoctoral positions on innate immunity and respiratory viruses from 2024
We are recruiting 2 postdoctoral fellows on innate immunity and respiratory viruses to work on the ERC-funded InVIRium project, for up to 4 and 5 years, respectively:
– 1 postdoctoral fellow with a strong expertise in the fields of innate immunity and virology (experience in BSL-3 lab, and with respiratory viruses required). Experience in 3D-cultures of primary airway epithelia would be a massive plus.
– 1 postdoctoral fellow with skills in bioinformatics (scRNA-seq and NGS analyses) and in wet lab experiments, with expertise in molecular virology.
The InVIRium project aims at understanding the relationships between respiratory viruses and their host cells, using highly pertinent models of airway epithelia cultured at the air-liquid interface, with a major focus on respiratory viruses (coronaviruses, influenza viruses and respiratory syncytial virus) and on interferon-induced antiviral restriction.
The IRIM offers access to all the facilities required for cutting-edge research, including BSL2 and BSL3 labs, state-of-the-art cell imaging and microscopy facilities, flow cytometry and cell sorting, genomics, and proteomics platforms. The IRIM constitutes a friendly and international working environment, with staff and students coming from around 25 different countries. Montpellier is a lovely city in the South of France, 15 km away from the Mediterranean sea and offering an amazing quality of life. The 2 positions will be available from the beginning of 2024.
Candidates should send their application (CV and motivation, plus contact for 2-3 referees) by email to Caroline Goujon
At a glance
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.
