#ResultatScientifique🔎| Dans le microbiote aussi, le collectif dépasse l’individu ! @acabirol.bsky.social montrent que les effets du microbiote intestinal sur le cerveau dépendent de l’ensemble de la communauté microbienne et non de bactéries isolées. 👋 @cbitoulouse.bsky.social

Les bactéries intestinales agissent en communauté pour influencer les capacités cognitives des abeilles

Mechanical forces shape the developing brain 🧠💥 Compression from high cell density doesn’t just squeeze cells - it compromises mitotic fidelity! New preprint on how mechanics impact neural development from Veronique Marthiens & co-authors @institutcurie.bsky.social @cbitoulouse.bsky.social 🧠🔧👇

Pleased to see this study out, combining experimental work from our lab at the @cbitoulouse.bsky.social, in particular by @nathaliebastie.bsky.social and @beckof.bsky.social, and from Laura Chaptal and @alengronne.bsky.social at IGH Montpellier @cnrs.fr @cnrsbiologie.bsky.social Congrats to all!

RNA Pol II-based regulations of chromosome folding

How transcription and cohesin complexes interact to regulate 3D genome organization remains unclear. Chapard et al. dissect their respective contributions and their interplay in shaping the genome arc...

Check out @julielebris.bsky.social’s thread on our latest manuscript describing phenotypic heterogeneity in capsule production in Klebsiella & Acinetobacter @klebclub.bsky.social This work started when I was still in @pasteur.fr & got finished in @cbitoulouse.bsky.social #microsky #phagesky

Julie Le Bris@julielebris.bsky.social · 12mo ago

Delighted to share our recently published work! Ever wondered how Klebsiella (and others) deals with capsule production’s costs ? The paper: journals.asm.org/doi/10.1128/... Thread👇

Is our gut epithelium a little cracked ? Turns out—yes🤯 , and especially around goblet cells! Check out the new preprint from our very talented neighbors @cbitoulouse.bsky.social👇

Denis Krndija@deniskrndija.bsky.social · last yr.

🥳 Thrilled to share our lab's first preprint, led by our talented postdoc Justine Creff! 👩🏻‍🔬 We tackled a fundamental question: how the epithelium withstands mechanical stress at the interface of cells with distinct geometries and mechanics, such as enterocytes (E) and goblet cells (G) (1/9)

Here our new preprint on the LPS holo-translocon doi.org/10.1101/2025... , collaboration with Yves Quentin @JulieMarcoux @fronzeslab.bsky.social @pstansfeld.bsky.social - @cbitoulouse.bsky.social

Structural Basis of Lipopolysaccharide Assembly by the Outer Membrane Translocon Holo-Complex

Lipopolysaccharide (LPS) assembly at the surfaces-exposed leaflet of the bacterial outer membrane (OM) is mediated by the OM LPS translocon. An essential transmembrane beta-barrel protein, LptD, and a...

Ribosomal RNA synthesis by RNA polymerase I is regulated by premature termination of transcription. Azouzi et al 2024 @cbitoulouse.bsky.social, bioRxiv doi.org/10.1101/2023.11.27.568781, peer reviewed by Review Commons eeb.embo.org/doi/10.1101/2023.11.27.568781.

Ribosomal RNA synthesis by RNA polymerase I is regulated by premature termination of transcription

The RNA polymerase I (Pol I) enzyme that synthesizes large rRNA precursors, exhibits high rate of pauses during elongation, indicative of a discontinuous process. We show here that Premature Terminati...
