Excited to share Wendy Le Mouëllic’s PhD work, now published in @pnas.org! It reveals that M. tuberculosis depends on inorganic sulfate import to survive inside host cells—fueling essential processes such as redox balance and stress resistance. Huge congrats to Wendy & colleagues! shorturl.at/WbFQC

After a PhD and two postdocs, I’m very proud to be joining the CNRS as a Chargé de recherche, this is a meaningful milestone. Huge thanks to Claude Bruand, @michaelglickman.bsky.social, and @oneyrolles.bsky.social for their guidance and support. Olivier, let’s turn this into exciting discoveries!

Pleased to highlight a new preprint from the lab. This is the work of my longtime collaborator in the lab Allison Fay, who wanated to create new tools for disocvery biology in mycobacteria, specifically a new sysem for protein localizaton and proximity proteomics. www.biorxiv.org/content/10.1...

Shout-out to @pierredupuy.bsky.social and colleagues! Excited to share our latest study, where we uncovered a previously unknown bacterial defense system in M. #tuberculosis: effluxosomes — dynamic membrane clusters that coordinate resistance to multiple toxic metals. shorturl.at/Ek0HD #MicroSky

Comment la bactérie responsable de la tuberculose survit-elle aux attaques des cellules immunitaires ? 🦠 Pierre Dupuy, lauréat d’une bourse postdoctorale Marie-Curie financée par l’UE, revient sur son projet. @cnrsbiologie.bsky.social @cnrs.fr @isabellesaves.bsky.social @oneyrolles.bsky.social

Excited to share our last study. Huge congrats to Sarah Monard, Arnaud Métais, @gclugo.bsky.social, @chrisverollet.bsky.social and all colleagues! We have found a mysterious cell type inside TB lung lesions that seems neuron-like but isn't quite a nerve cell. Let's dive in👇 shorturl.at/x4Sb5
