Hâte de venir te voir, et de suivre tes aventures ….😍

Many congratulations again ☺️🥳

Poly-immunity arrays associated with Rhs toxins confer wide protection against competitors Martinkus et al. show that Photorhabdus and Xenorhabdus species encode arrays of immunity genes whose protein products neutralize toxins secreted by competitors. These arrays, often linked to Xer pass...

Happy to share the last work of @jmartinkus.bsky.social, led by @dukasju.bsky.social
Immunity arrays associated with Rhs and CDI toxins and linked to a novel genetic element (XPC cassette) confer protection against competitors. @currentbiology.bsky.social
Kudos !!

Fantastic work from the fantastic @maellepllt.bsky.social 😍

What if even the core of bacterial nanomachines wasn’t static?

We found that the T3SS core protein SctD in Yersinia dynamically exchanges subunits — and this flexibility is essential for proper assembly & function.

Rosalind Franklin and the damage of gender harassment Spurred by a recent report on sexual harassment in academia, our columnist revisits a historical case and reflects on what has changed—and what hasn’t

Thinking only of Rosalind Franklin today, and what was stolen from her (and so many other female scientists alongside her).

Open position to work on Type IX secretion (#T9SS) in our lab, in collaboration withe the group of Eric Reynolds at the Dental School of the University of Melbourne. Please spread the word, and forward to anyone potentially interested ! Apply here:

Very proud to be part of an amazing organising committee, huge thanks to @maellepllt.bsky.social @cascaleslab.bsky.social @thicoz.bsky.social and Romé Voulhoux

Amazing science at the 2nd edition of the Secretion Days in Marseille 🌞 ! Huge thanks to all participants and to @archaellum.bsky.social for an outstanding opening talk. Looking forward to the next edition!

Pyrazinamide kills Mycobacterium tuberculosis via pH-driven weak-acid permeation and cytosolic acidification Pyrazinamide (PZA) is a cornerstone drug in tuberculosis (TB) treatment with a strong bactericidal activity in vivo on both actively and non-replicating bacterial subpopulations. Yet the precise mode ...

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! 🧫🦠💊🥼🩺

Widespread deployment of the human CD38 ADP-ribosyl cyclase fold in antibacterial and anti-eukaryotic polymorphic toxins Bacterial polymorphic toxins are modular weapons that mediate inter-microbial competition and host interactions by delivering diverse cytotoxic domains through specialized secretion systems. Here, we ...

Happy to share our work on a T6SS effector with ADP ribose cyclase activity, published in JBC @asbmbjournals.bsky.social
Great work of Julius Martinkus @jmartinkus.bsky.social and (always) great collaboration with @dukasju.bsky.social and @laurentterradot.bsky.social

We recently described how T3SS effectors reach the injectisome with a shuttle system. But what about their chaperones? With live microscopy, proximity labeling and functional assays, @keithpint.bsky.social showed the Yersinia chaperone SycH already hands over its cargo in the cytosol. bit.ly/47hq6rM

🚨🔥 Happy to share our latest Preprint! 🔥🚨

We describe some very simple experimental approaches employed in our group to assess CRISPRi effectiveness in Mycobacteria 🧬 🦠 🧫
