Want to hear a mid-career PI pontificate about science, career and cooking? Today's your lucky day thanks to The Microscopists podcast! Thanks Peter @yorkbioimaging.bsky.social for having me 🎙️🎧 themicroscopists.bitesizebio.com/episodes/chr...

During chlorite-induced #OxidativeStress MsrPQ repairs periplasmic proteins oxidized at Met residues. @ben-ezraty.bsky.social &co show that in these conditions the #Ecoli chaperone Spy is overproduced & oxidized; its reduction by MsrPQ helps maintain functionality @plosbiology.org 🧪 plos.io/3VHTAI9

Now published! www.nature.com/articles/s41... Very nice collaboration with Hoogenboom ( @ucl.ac.uk ) and Bonev ( @uniofnottingham.bsky.social ) labs.

Extremely happy to share the fruit of a beautiful collaborative research study. France 🇫🇷, Russia 🇷🇺 and USA 🇺🇸 teaming up to tackle a long-standing question in the TB field! 🧫🦠💊🥼🩺 Our latest Preprint on Pyrazinamide Mode of Action against M.tuberculosis is online! 👇👇👇 doi.org/10.1101/2025...

New study shows pyrazinamide kills TB by acidifying bacterial cytosol — not via PanD/CoA depletion. A long-standing debate settled, paving the way for smarter PZA-like drugs. #MicroSky ✍️ J. Laudouze, Y. Antonenko, @alexandregouzy.bsky.social, @pierresantucci.bsky.social & coll. 📖 shorturl.at/tuz6Q

Great collaborative work driven by @pierresantucci.bsky.social which provides clear evidence on the mode of action of a well-known first-line anti-TB drug.

We will have soon an Open position for a PhD thesis position to work on bacterial secretion systems ! Stay tuned !!

📝New preprint! #MicroSky 🕰️We chart the full, synchronized lifecycle of a predatory bacterium using Hi-C, RNA-seq, ChIP-seq & microscopy. 🧬We uncover dramatic shifts in nucleoid architecture & transcription, tightly coordinated with predation. www.biorxiv.org/content/10.1...

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
