The Institute of Human Genetics is working at the forefront of the scientific response to COVID-19
During the developing COVID-19 pandemic the Institute of Human Genetics and its researchers are playing their part in tackling the virus.
We have set 2 objectives.
The first concerns the optimization of the RT-PCR test by eliminating the RNA extraction step from patient samples and the miniaturization of the test to allow the development of a new large-scale test based on massive sequencing and intended for screening the population.
The second, aimed at screening for antiviral activity using a targeted FDA-approved drugs. Thus, we isolated SARS-Cov-2 from patient nasopharyngeal sample, established an infectivity assay, TCID50 assay and viral RNA quantification
assay using RT-qPCR.
Thanks to Montpellier Biocampus MGX, , researchers from the LPHI and CEMIPAI facility we were able to successfully achieve our objectives.
Indeed, we have successfully developed a SARS-Cov-2 NGS based detection using nasopharyngeal swab samples (Figure 1). The procedure is currently under validation by the National Reference Center at the Pasteur institute in Parisinstitute in Paris. Our objective is transferring this technology to medical biology laboratories in order to perform large scale COVID-19 testing.
Our objective is transferring this technology to medical biology laboratories in order to perform large scale COVID-19 testing. Our screening using targeted FDA-approved drugs allowed us to identify two compounds with a strong antiviral activity in vitro (patent pending). We are currently exploring the molecular mechanism
involved (Figure 2). Three IGH researchers, Clement Mettling (1), Gael Petitjean (2) and Monsef Benkirane, have worked around the clock to achieve these objectives. We are delighted to Laurence Berry and Talip Aydogan from the LPHI and Franck Godiard from the UM who performed electron microscopy on SARS-cov-2 particles and infected cells (Figure 3), Delphine Muriaux and Sébastien Lyonnais from CEMIPAI for performing Atomic force microscopy (Figure 4), Laurent Journot and all the members of the Montpellier GenomiX facility and Vincent Foulongne and Michel Segondy from the Montpellier Hospital for providing valuable patient samples. We are grateful to Olivier Schawartz from the Institut Pasteur for sharing A549 expressing ACE2 cells and Delphine Muriaux for sharing VeroE6 cells.
Great thanks to the CNRS president, Antoine Petit, André Le Bivic INSB director and Philippe Augé (University of Montpellier director). Finally, we are grateful to Frédérique Vidal, minister of high education and research, for her visit to IGH (3-5) and for the constructive discussions and support.

Senior Group Leader Position Institut de Génétique Humaine CNRS-université de Montpellier, Montpellier, France
The Institute of Human Genetics (IGH) of Montpellier opens a call for applications to host an established senior research group to foster interdisciplinary research and innovation in the fields of Nuclear dynamics, Computational Biology, Developmental biology, Cancer and Infectious Diseases.
The IGH is a world-class biology and biomedical science Institute. It provides an exciting scientific environment and benefits from core funding of the CNRS and the University of Montpellier. The IGH is located in the biomedical campus Arnaud de Villeneuve, which is connected to the University Hospitals and the Faculty of Medicine. In addition to IGH, the campus includes the Institute of Functional Genomics, the Center for Structural Biochemistry and the Genopolys Science Outreach center, boasting a research area of over 15,000 m2. This excellent scientific environment is supported by BioCampus Montpellier, a service unit providing a wide range of state-of-the-art facilities, including Genomics, Proteomics, medium and high-throughput Screening, Imaging, Animal Facilities and high-end instrumentation for Structural Biology and Biophysics.
The group leader should have a permanent French academic position. Selection of candidates will be based on international scientific excellence. Particular attention will be given to innovative, high-risk projects. Selected group leaders will receive lab space and support from the IGH, in addition to strong assistance from the grant office for the preparation of applications for grants from French and European agencies.
- Application deadline: Jun 30, 2019.
- Notification to shortlisted applicants: July 15
- Interviews of shortlisted candidates by September 30
- Starting date for the position: January 2021
