Group Leader
The primary goal of our research group is to enhance understanding of host-pathogen interactions in TB and TB/HIV coinfection at the molecular and cellular levels. This includes discovering novel virulence genes in M. tuberculosis and identifying immune mechanisms involved in host defense against these pathogens, with the ultimate aim of proposing improved strategies for disease control.
We study host-pathogen interactions in tuberculosis, with a special interest in deciphering immunity to TB and the links between M. tuberculosis evolution, physiology and virulence.
Our research focuses on exploring the connections between metabolism and virulence in the TB bacillus, Mycobacterium tuberculosis, and how these connections have evolved over time. Specifically, we utilize transposon mutant library screening (Tn-seq) to identify genes and pathways involved in host-pathogen interactions in TB. Notably, we have identified a novel mechanism of innate immune control of pathogens through zinc intoxication and discovered resistance strategies in pathogenic mycobacteria involving P-ATPases. Currently, we are elucidating the function of several P-ATPases and their metallochaperones in the physiology and virulence of M. tuberculosis. Additionally, we employ Tn-seq analysis to investigate how M. tuberculosis adapts to various host-imposed stresses, particularly hypoxia.
Our lab is also focused on understanding innate and adaptive immunity to TB. Specifically, we are investigating the role of innate receptors, particularly C-type lectins, and host cell-expressed glycans in anti-mycobacterial immunity. For example, we recently discovered that the C-type lectin DCIR modulates immunity to TB by maintaining type I interferon signaling in dendritic cells. We are deciphering the molecular mechanisms involved in DCIR signaling through biochemical and (phospho)proteomic experiments.
Additionally, we are exploring the role of cytotoxic T cells in the host defense against M. tuberculosis. In this context, we are developing imaging and functional approaches to determine which subpopulations of T lymphocytes have optimal access, interaction, and functional properties for targeting M. tuberculosis-infected cells.
Finally, in the context of TB/HIV co-infection, a leading hypothesis is that infection of macrophages by M. tuberculosismodulates the local inflammatory environment, promoting HIV-1 replication. We are currently using various in vitro approaches to simulate this ‘bystander’ effect originating from sites of M. tuberculosis infection, aiming to dissect the molecular and cellular mechanisms that increase the susceptibility of human monocytes and macrophages to HIV-1 infection. In parallel, we are correlating our in vitro findings with in vivo observations by studying pulmonary lesions in non-human primates and analyzing human samples, including sera and pleural effusion fluid. Our ultimate goal is to identify novel targets with diagnostic and therapeutic potential to address the co-morbidity between AIDS and TB.

November 2020 – Olivier Neyrolles is awarded the Jacques Piraud Prize from the Fondation pour la Recherche Médicale.
October 2018 – The 2018 PEPS Prize for Pedagogical Innovation is awarded to the IMMUNOVA project (Active, interactive and flexible learning in immunology) led by 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).
