Presentation

The MCV team is dedicated to the study of positive-strand RNA viruses. The main objectives are to better understand how these viruses interact with their host at the cellular and molecular level. The studied viral models are hepatitis C virus (HCV), hepatitis E virus (HEV) and coronaviruses. For more than 26 years, the team has been studying the HCV life cycle and it has largely contributed to the understanding of several steps of entry, replication and assembly of this virus. In 2013-2014, after the development of potent antivirals against HCV, the team has expanded its viral models by working on HEV and highly pathogenic coronaviruses like MERS-CoV and, since 2020, SARS-CoV-2. These viruses are emerging in human populations and can be life threatening. Our objective is to better understand the life cycle of these viruses and identify novel antiviral compounds.

Highlights

  • Since the beginning of the COVID-19 pandemic, the MCV team has rapidly used its expertise in the field of research on coronaviruses to develop useful tools for SARS-CoV-2. This new virus has rapidly been amplified in cell culture in our BSL3 facility and we have developed a high-throughput screening to interrogate several chemical libraries containing active molecules contained in medicines with the objective of rapidly identifying and characterizing antiviral molecules being or having been licensed for the treatment of other pathologies not linked with viral respiratory infections. This approach can rapidly lead to the repositioning of the most potent molecules for the treatment of COVID-19. Our screening has led us to the rapid identification of a molecule showing a very good antiviral activity against SARS-CoV-2 in addition to interesting pharmacological properties which allow us to propose it for a repositioning to treat COVID-19 patients after validation in a clinical trial that will begin in early 2021.
  • Hepatitis E virus (HEV) infection is a major public health problem that affects both developing countries and also industrialized countries like France. Hauts-de-France is a region very affected by this infection. It is important to better understand how this virus works, to treat it better, but also to better diagnose this infection. In our laboratory, we have shown that, during its infectious cycle, HEV produces several forms of its capsid protein ORF2 (structure surrounding and protecting the viral genome), but only one is associated with infectious viral particles. We are currently studying the mechanisms by which these different forms of ORF2 are produced. In addition, we have generated antibodies specifically recognizing the ORF2 forms and are working on the development of a new diagnostic test for hepatitis E.
