Time for some insights into our latest #preprint

Using cryo–electron tomography, we peeked inside different #Mtuberculosis strains, and a couple of other mycobacteria.🧐 Surprise: some species, especially the host-adapted ones, build intracytoplasmic membranes (we call them MIMs)! 🦠

After years of hard work and months of growing MTB @camimille.bsky.social submitted her story ! Check this out if you wanna discover new intrabacterial structures and their function ! 🦠🔬✨

Very happy to have participated in #ETOX2025 ! Very nice science, amazing crowd and wonderful place ! I was happy to present a poster of my work to a lot of old and new friends and colleagues. Thanks to the organizer for all their work and I hope to come back in two years !

A massive thank you to all the incredible participants and speakers who made ETOX 2025 in the Basque Country an unforgettable event! Your insights, discussions, and passion for bacterial protein toxins have truly advanced the field. We're already looking forward to next time! #ETOX2025

Zoom into a human cell infected by Shigella, the bacteria behind dysentery. Using cryo-EM, @leaswistak.bsky.social and team revealed how it pierces cells with molecular syringes. Stunning science at the nanoscale.

How do intracellular #bacteria breach vacuoles to enter the host cytosol? @leaswistak.bsky.social @matthijnvos.bsky.social @enningalab.bsky.social &co show that #Shigella uses its T3SS system to damage endomembranes via mechanoporation to initiate cytosolic access @plosbiology.org 🧪 plos.io/4jXrr9Z

No one mourns the Wicked ! Some 🟢Elphaba🟢 colored actin and cytosolic 🟣Glinda magic🟣.
Steer all this with 🔵 Hoescht, Shigella and 🟡 Rab35 (PMID : 38568808 😉) and you get these sparkling cells, perfect for #FluorescenceFriday

The Institut Pasteur has decided to leave X (formerly Twitter) to join BlueSky! 🦋
The Institut Pasteur made this decision due to several serious issues observed on the X platform since its acquisition. Join us here to continue advocating for science. www.pasteur.fr/en/home/pres...

Happy to share our latest preprint on dormant #Salmonella and the role of SifA for intravacuolar nutrition! Thanks to all the co-authors!
