New paper from the @rouxlab.bsky.social on Nature Communications! We study how membrane tension is spatially organized in cells. Using the mechanosensitive probe Flipper-TR to visualize tension across the plasma membrane of adherent cells and to dissect the conditions needed for a gradient to happen

📢 New preprint !
Please check if you are interested in the comparison between 2d and 3d nematic theories 🤔

I show that the 2d description can lead to artefacts on curved surfaces, and I propose a thin film description of nematic shells with full 3d orientation !

This was a funny summer project 😊

Why would Mycobacterium shed its surface right after entering a host cell? Host phagocytes rapidly strip its outer layer, releasing components that alert neighbors and trigger defense responses

Our preprint is out, curious to hear your take! 👀

Maria Tettamanti shows that inhibition of TORC2 by the small amphipath PalmC induces the TORC2-dependent internalization of sterols. Congrats to Maria and all coworkers involved, and to EMBOj for the efficient review process: use review commons! @biology-unige.bsky.social @sciencesunige.bsky.social
Yeast cells utilize a TORC2 feedback loop for plasma membrane adaptation to mechanical stress, with increased sterol transport from plasma membrane to endoplasmic reticulum activating TORC2 signaling

🚨 Great story released by @gm-charriere.bsky.social and co.!
They identified and characterised a natural interaction between amoebae and Vibrio, pointing to Paramoeba as a potential reservoir of oyster pathogens 🦪
Congrats! 🥂

What better way to wrap up the Soldati tour than with a fantastic talk from @mel-foulon.bsky.social? 🎤
She enjoyed “shedding” her enthusiasm for Myco lipids with such a brilliant crowd of passionate scientists at #EMBOcellBioHostPath! 🧫✨

Did you know the cell wall of mycobacteria isn’t just for protection? 🧱👀 Here, Mycobacterium marinum sheds its outer capsule right after being eaten by Dicty! A sneaky move that affects even nearby cells… #FluorescenceFriday #Mycobacteria #CellBiology #Infection #3Rmodels #Phagocytosis

Bacteria have a simple yet potent mechanism that controls their sensitivity to environmental stimuli.
