New NeuroCyto preprint about to drop! @wiesner-t.bsky.social 😎⏳

www.sciencedirect.com/science/arti... check out the recent dispatch on endolysosomes and melano-biology interplay in @currentbiology.bsky.social by @delevoyecedric.bsky.social & @laurasalavessa.bsky.social from @membramics-lab.bsky.social

If you're interested in trafficking of #myelin constituents in #oligodendrocytes, and of course you are, you may want to check out our new preprint. It's very nice PhD work by @sophiesiems.bsky.social, and we're grateful to all who contributed! www.biorxiv.org/content/10.1...

Happy to contribute to this new work from @micoxscopy.bsky.social et al, helping apply SSQUASH to analyse the shape of spectrin rings along axons. Data analysis is the next frontier in SMLM, and I'm always up for chatting, sharing data and see how we can push things further!

Hello microscopy and imaging experts and enthusiasts! We are looking for a staff scientist to join us here in Geneva to work on microscopy and image analysis projects! See the link for the job announcement (in French and in English). Please apply and/or repost! jobs.unige.ch/www/wd_porta...

How do cells switch on the actin assembly at endocytic sites? How can this on-switch evolve? Check out our new preprint! www.biorxiv.org/content/10.1...

I'm grateful for the Research Council of Finland for granting me the Academy Research fellowship! After getting over the shock I will soon move back to Finland to start as a group leader at the Institute of Biotechnology @helsinki.fi. Looking for a PhD student soon! www.aka.fi/en/about-us/...

💥 Very cool science session at the @academiesciences.bsky.social with @christlet.bsky.social for the "Grandes avancées Françaises en biologie" 🎖prize to @florianwerner.bsky.social and @moparthisk.bsky.social Check out the live stream here m.youtube.com/watch?v=PIWI...

Honored to be on stage this morning @academiesciences.bsky.social for the work done with @florianwerner.bsky.social and @moparthisk.bsky.social. Also celebrating almost ten years of collaboration and friendship with @stefvass.bsky.social, merging microscopies to discover new biology 🤝

Fierté de DU @inp-marseille.bsky.social : voir les travaux de Florian Werner et Satish Moparthi avec @christlet.bsky.social @stefvass.bsky.social aux 20 ans des grandes avancées françaises en biologie @academiesciences.bsky.social Bravo à eux ! @cnrsbiologie.bsky.social @univ-amu.fr @cnrs.fr

🎉 It's such a pleasure to congratulate Nicolas Jullien, full-stack ingénieur, CRISPR wizard in the NeuroCyto team, software developer extraordinaire and more, who was awarded the @cnrs.fr crystal medal! Thank you @nico-juulien.bsky.social 🙏https://www.insb.cnrs.fr/fr/personne/nicolas-jullien/

#Communiqué 🗞️ Des scientifiques ont réalisé une avancée majeure dans le traitement d’une maladie musculaire génétique grave pour laquelle il n'existe actuellement aucune thérapie, la myopathie centronucléaire liée à la mutation du gène BIN1. 👉 www.cnrs.fr/fr/presse/un...

Acknowledgments slide done! Time to rehearse for @academiesciences.bsky.social

This is a summary of our recent @jcellsci.bsky.social paper. If you've ever wondered why ATG9A has many and varied roles, we think it's because it is trafficked by a subset of a large, diverse family of vesicles - intracellular nanovesicles. doi.org/10.1242/jcs....

This will be at the Académie des Sciences on June 17th, for the 20th anniversary of the “Grandes Avancées Françaises en Biologie” prize. More info here: www.academie-sciences.fr/en/node/2699

💥🔬💥

Great talks these two last days, including Marc Bitoun (Institut de Myologie, Paris) as keynote speaker who showed impressive data on allele-specific silencing therapy for centronuclear myopathy due to dyn2 mutations.

Congrats @wiesner-t.bsky.social who gave a great talk at the Exo-Endo Meeting yesterday, showing how the acitn-spectrin scaffold regulates exocytosis along the axon shaft!

Interesting new #NatureNeuro paper: Autism-related traits in myotonic dystrophy type 1 model mice are due to MBNL sequestration and RNA mis-splicing of autism-risk genes. #Myoblue tinyurl.com/ysvwdejm

Congrats to my fantastic coauthors on this work with a surprising conclusion. www.biorxiv.org/content/10.1...

We have a new review out! In this Microscopy & Microanalysis piece, Louisa Mezache and I survey some of the latest commercially available microscope technologies: Nikon NSPARC, Re-scan Gaia, CSR Biotech MI-SIM, refinements to STED, SMLM from Bruker and Abbelight… Check it out with free access:

Very happy to present the latest preprint of the lab. This was work done predominantly by a Master student, Leonardo Tadini, assisted by Lilia Younsi, Isabel Holguera, Felix Simon, and Max Courgeon: www.biorxiv.org/content/10.1...

James and Selena's paper is out in @jcb.org ! We present a structural model of the TACC3-ch-TOG interaction. Using Affimers that can inhibit this interaction, we uncovered a new role for TACC3-ch-TOG in maintaining the pericentriolar material during mitosis. 🧪 1/n doi.org/10.1083/jcb....

More white coats, less white robes! @eddpasquier.bsky.social #standupforscience #standupforscience2025

Unique opportunity to join the CytoMorpho Lab (in Paris ❤️) as a postdoc to work on the self-organization and polarization of reconstituted networks made of microtubules, motors and actin filaments in vitro. Experience required. Please Repost 🙏 thanks !

The #nucleus contains the info of a #cell, but it does much more than that !! Since the nucleus is *big*, acts as the main intracellular obstacle, and during #CellMigration can get 'trapped'/stuck until the cell pushes it FWD. #scicomm @focalplane.bsky.social @cellcommlab.bsky.social #Skyscience

Deeply saddened by the passing of Prof. Mike Sheetz, a true leader in Mechanobiology. His groundbreaking work on Kinesin, membrane organization, and mechanotransduction has left an indelible mark. A tremendous loss to science. #Mechanobiology #Science #LaskerAward

What a sad news. Steve was an outstanding scientist and contributed greatly to midbody and centrosome biology. He was also a great colleague and an accomplished mountaineer. I will miss our scientific discussions and great hikes we did in Colorado. www.mercadantefuneral.com/obituaries/s...

Our first paper on BlueSky!! Remarkable work published in @currentbiology.bsky.social from Jing Xie, Javad Najafi and others, on how cell shape affects mitotic spindle positioning forces in embryos, by impacting cytoplasm flows. @ijmonod.bsky.social www.sciencedirect.com/science/arti...
