That’s a wrap for #JCSimaging, organised by @franbottanelli.bsky.social, @guijacquemet.bsky.social, @drmichaelway.bsky.social & Giulia Zanetti. Thanks to everyone who joined us and made the conference such a wonderful community event. journals.biologists.com/jcs

Beautiful location here at #JCSimaging

@jcellsci.bsky.social @biologists.bsky.social team ready to welcome everybody and the sun is shining! #JCSimaging

Phagocytic podosomes enable efficient uptake of Candida auris by primary human macrophages

Podosomes in phagocytosis! 😋 + Candida auris Our new paper "Phagocytic podosomes enable efficient uptake of Candida auris by primary human macrophages" has now been published in Cell Reports: pubmed.ncbi.nlm.nih.gov/41863801/

Podosomes in endocytosis! 🔬 Check out our new preprint "Drebrin forms a cortical hub that connects actin, microtubules, and clathrin for endocytic transport of β2 integrin" www.biorxiv.org/content/10.6...

New publication: Live Biological Imaging Across Scales 10 chapters on live imaging from molecules to organisms, written by leading experts and edited by Claire Wells and yours truly Can now be pre-ordered by your online or brick-and-mortar vendor of choice 🔬

Ho ho ho 🎄🎅

A warm welcome to our new PhD student Emma Lautenbach, who will work on the intricacies of the podosome cap 🧢

A warm welcome to our new lab member Canberk Yesilada, who will be/is already working on his PhD thesis on Borrelia phagocytosis by macrophages 🤗

Macrophages are super! SoRA (superresolution after optical reassignment) microscopy video of a primary human macrophage transfected with Lifeact-GFP to visualize actin-rich podosomes. Star-like appearance is due to connecting cables linking individual podosomes into a cell-wide superstructure ✨

On our way to Heidelberg to the meeting of the German Society for Cell Biology 🧫

New preprint: Phagocytic podosomes enable efficient uptake of Candida auris by primary human macrophages 🦠👄 www.biorxiv.org/content/10.1...

Our paper on podosome regulation by myosins 1e/f is now online. We introduce the concept of the podosome base, a region of plasma membrane-associated components 🔬 Cool collaboration with @renaudpoincloux.bsky.social‬ and Krendel labs www.sciencedirect.com/science/arti...

Congratulations to our lab member Bryan Barcelona to a super fancy defense on software-based analysis of cell and podosome parameters 👨‍🎓

Cellular fireworks (in a primary human macrophage): Microtubule +tips, labeled by CLIP170-GFP, move from the microtubule organizing center (MTOC) to the cell periphery ✨

This is why we love #cellmigration #Leukocytes: #Neutrophils (cyan) #Macrophages (orange) chemotaxis. I couldn't share it before the retirement of @zebrafishrock.bsky.social, but cool #microscopy in #zebrafish continue to rock ! #scicomm #scisky @cellcommlab.bsky.social @focalplane.bsky.social 🧪🔬

A warm welcome to our new master student Mahmood Tarmom, who will work on podosome proteins of (yet) unknown function 🔬

Coming up: "Live Biological Imaging Across Scales", part of the Royal Microscopic Society line of Wiley books. Featuring 10 chapters from international experts on live imaging from molecules to organisms. Edited by Claire M. Wells and yours truly 📘🧬🐭

Our preprint on podosome regulation by unconventional myosins in now on BioRxiv. Great collaboration with the @renaudpoincloux.bsky.social and Krendel labs. www.biorxiv.org/content/10.1... We introduce the concept of the "podosome base", a region of plasma membrane-associated podosome components.
