How do nutrients shape antibiotic efficacy? The Lewis lab shows that limited essential precursors restrict antibiotic target activity during nitrogen starvation. We've written a comment on what this brings to the field and the challenges ahead. Both open access, links below!

Proud to share the first paper from the Ronneau Lab in @NatureComms
! We uncover how stress-induced Fe–S cluster damage reshapes bacterial physiology through the stringent response. Check it out! nature.com/articles/s41467-0…

E. faecalis lactic acid suppresses macrophages
Enterococcus faecalis-derived lactic acid suppresses macrophage NF-κB activation via MCT-1 & GPR81. This lactic-acid-driven immunosuppression promotes bacterial persistence & polymicrobial infection

Happy to share our lastest story (with @HallezLab, @LBarquist, @CMichaux13) ! We show how host-relevant stress disrupts Fe-S cluster stability, tuning (p)ppGpp levels to control bacterial adaptation and trigger virulence.

🪢 PROJET PPRA 6/25
En réponse au besoin urgent de développer de nouveaux agents thérapeutiques, le projet NAILR se fonde sur la caractérisation de quatre composés d’une nouvelle famille de peptidomimétiques anti-infectieux produits par une toxine bactérienne👇

With @CostaT_Lab, we challenged AI co-scientist to generate scientific hypotheses. It correctly predicted how cf-PICIs spread between bacterial species, matching our unpublished, experimentally confirmed mechanism! 🤯@imperialcollege @FlemingCentre

Happy to share our latest work published in @PNASNews In collaboration with @yanjiechao , we uncovered an RNase III-processed sRNA, ManS, that orchestrates sialic acid metabolism in Salmonella enterica during gut colonization.

Our paper on 🦠queuosine 34 modification of tRNA tyrosine and antibiotic response is finally out in its final form in @eLife ... and quite different from the preprint version. Many thanks to reviewers, editors and kudos to all authors🙏 elifesciences.org/articles/9…

Is it anything Hfq-like (RNA chaperone)? Or similar to CsrA (global translation modulator)? We don't know yet. But as it stands, Bacteroidota RRM proteins appear as excellent candidates to map post-transcriptional networks in gut microbiota species. nature.com/articles/s41467-0…

Thrilled to share the final version of my postdoc project, out today in @Nature!
We investigated the Bil system – a ubiquitin-like antiphage defense system – and discovered a new defense mechanism!
More info in the thread below 👇
