The main goal of our research group is to better understand host-pathogen interactions in TB on the molecular and cellular levels, from the discovery of novel virulence genes in Mycobacterium tuberculosis to the identification of immune mechanisms involved in host defense against the pathogen, with the overall objective of proposing better strategies to control disease.
Our research aims at exploring the links between mycobacterial evolution, physiology and virulence, and between host cell metabolism and immunity to M. tuberculosis in the context of TB and TB co-infections (e.g. HIV) using a combination of global ‘omics’ approaches and candidate-based studies, from the single molecule to the whole organism level.
Our team is highly interdisciplinary, involving scientists and professors in biochemistry, microbial genetics and immunology, and works in close collaboration with other laboratories worldwide in the context of several national and international networks supported by national (e.g. Agence Nationale de la Recherche, Fondation pour la Recherche Médicale, Fondation Bettencourt-Schueller) and international (e.g. European Union H2020 program) funding bodies.

MbcT toxin induces death of Mycobacterium tuberculosis.
When the MbcT toxin is produced in the absence of its antidote, it kills the bacteria (shown in red).

October 2018 - The 2018 PEPS Prize for Pedagogical Innovation is awarded to the IMMUNOVA project (Active, interactive and flexible learning in immunology) led by Prof. Denis Hudrisier.
The IMMUNOVA project is composed of two axes: the first is the strong use of digital resources allowing the students to prepare themselves before and after the face-to-face sessions (also available online), which provides greater flexibility and learning autonomy for all students, especially those who cannot attend classes according to established schedules; for the second axis, the students are offered to conduct team projects in immunology according to different approaches (e.g., digital resource generation, interviews with researchers, 3D printing of proteins in FabLabs, conception of serious games).
December 2017 - Dr. Anthony Troegeler is awarded the Bretesche Prize in medicine from the Toulouse Academy of sciences.
Anthony did his PhD studies in our lab where he worked on the role of the innate immune receptor DCIR in immunity to tuberculosis. His work was published in January 2017 in Proc Natl Acad Sci USA. He will receive the Prize on December 3 at the Hôtel d'Assézat, Toulouse.
