Huge congratulations to Wieczorek Lab PhD student Bin Cai and now-PI Jingwei Xu @xujwet.bsky.social on figuring out the surprisingly complex structure of the A-C linker crosslinking microtubule triplets in Tetrahymena basal body centrioles! www.science.org/doi/10.1126/...

🚨 New preprint out!
“Fluorescence lifetime estimation: a practical approach using Flipper-TR FLIM” with Tithi Mandal and @rouxlab.bsky.social
We benchmark and describe step-by-step Flipper-TR FLIM measurements across different set-ups and and strategies.

Can’t wait for the BioMatter Meeting in beautiful Arolla 🇨🇭⛰️
Amazing lineup of speakers + cutting-edge science on cytoskeleton dynamics from cells to tissues.
See you there!

🔎New preprint!
We reveal a physiological role for tubulin autoregulation, fine-tuning microtubule dynamics and preserving 3D cellular architecture.
Big thanks to @ivanagasic.bsky.social and team!

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

New lab preprint! Unveiling the Molecular Architecture of T Cells and Immune Synapses with Cryo-Expansion Microscopy (Cryo-ExM). A fantastic collaboration with Dr. Benita Wolf. Congratulations to all authors, especially Florent Lemaitre, for leading this amazing work! www.biorxiv.org/content/10.1...

🔬 A new probe developed by Janelia researchers & collaborators that enables visualization of extracellular matrix structure in live tissues could also be useful in studying diseases linked to changes in the extracellular matrix and in diagnostic imaging ➡️ www.janelia.org/news/looking...

This stunning image was made by @ac-almeida.bsky.social , our brilliant President and microtubule enthusiast! She's passionate about how the cytoskeleton organizes itself in 3D—seriously cool stuff! 🧠🧵✨#Microscopy #WomenInSTEM #Cytoskeleton
