Hello epithelia enthusiasts! I’m @inesfournon.bsky.social and I study epithelial mechanics in sea anemones 🪼 Did you know epithelial cell extrusion had never been described outside bilaterian animals before? Well… not anymore 👀 Read ⬇️🧵1/9

How is developmental speed regulated ? 🪰 Happy to share my PhD story from Schweisguth Lab @devstempasteur.bsky.social. Here we show that cellular NAD+ availability and redox constrain developmental speed in the fly eye. www.biorxiv.org/content/10.1... A big thanks to everyone involved!

Check out my first #preLight on the work of Sokol's team exploring PCP and mechanosensation! It was so much fun to pick a preprint, read it, write about it, and even get to ask the authors questions directly. I have a feeling this is just the beginning of many more preLight posts to come! 🙌

Stretch it, wound it, pull it: ADIP-Diversin polarizes anyway. Characterization of a new mechanosensitive polarity module 🐸 First #preLight from @alinegrata.bsky.social, highlighting #preprint from Chih-Wen Chu, Satheeja Velayudhan, Sergei Sokol and team: prelights.biologists.com/highlights/m...

Epithelial morphogenesis is all about how epithelial tissues develop unique shapes and structures! I'm @nehaghosh.bsky.social and will share some research in this area.

Super excited to share that the final version of our study on the role of Adenylate Kinase 7 (AK7) on centriole maturation is finally out! @devbiol.bsky.social Read the full version here: www.sciencedirect.com/science/arti...

Centriolar defects underlie a primary ciliary dyskinesia phenotype in an adenylate kinase 7 deficient ciliated epithelium

The skin of Xenopus embryos contains numerous multiciliated cells (MCCs), which collectively generate a directed fluid flow across the epithelial surf…

The effector caspases drive cell death, but their activation can often be survived, so how do cells make this decision? Our new preprint from @levayerr.bsky.social shows that instantaneous caspase activity is important, but past activation has a key role to play! www.biorxiv.org/content/10.1...

New article alert! Ever met someone who looks exactly like you? Science says it’s more than a coincidence! Read more on the science of look alikes in our latest piece, written by Silvia, PhD student in epigenetics🧬 www.piplettes-pasteur.com/post/you-may...

You may have a twin and you don’t know it: the science of look-alikes

Perhaps someone has already told you that you look like someone else, but is it actually true? It is! Science suggests that there is someone in the world that looks like you and that even shares your ...

In their Cell Science at a Glance article, @alinegrata.bsky.social & @levayerr.bsky.social @pasteur.fr describe the remodelling steps that take place within dying or extruding cells, outlining the commonalities & variations between tissues &organisms. journals.biologists.com/jcs/article/...

So happy to share that our review on epithelial cell extrusion is out! @levayerr.bsky.social Extrusion is such a plastic, context-dependent process, so capturing it visually in the poster that accompanies the article was a super challenging but fun task! journals.biologists.com/jcs/article/...

Just wrapped up an amazing 2-week Principles and Applications of Fluorescent Microscopy #PAFM course @pasteur.fr! Built a microscope, designed a confocal, attended great talks, and got hands-on with the latest tech🔬💡 Great mix of theory and practice. 10/10, highly recommend!🤩 #microscopy #biology

Check out this great article 🫶🏼 Whales, oceans, hearts adaptations, and whatnot🔬✨ Also available in French 🇫🇷 ! @piplettesmagazine.bsky.social
