Not every cell react the same way to caspase activation. In our recent study (led by @tomcumming.bsky.social and initiated by @avillars.bsky.social ), we tried to better understand what explains this difference and outlined a role of past caspase exposure 👇 www.nature.com/articles/s41...

🚨 New preprint alert! 🚨 Choanoflagellates reorganize their global cytoskeletal architecture within seconds to explore confined microspaces. This is the main PhD work of the amazing @maitefreired.bsky.social www.biorxiv.org/content/10.6... A tread 🧵⬇️

Rapid repurposing of microvillar content drives a flagellate-to-amoeboid switch in the closest relative of animals
Animal cells extensively remodel their cytoskeleton during differentiation and can notably switch between two major motility modes: flagellum-based swimming and actin-based crawling. We previously sho...

🚨 New pre-print alert! 🚨 Adult neural stem cell state and fate decisions are hidden within transcriptional heterogeneity. To find out how we decoded these heterogeneities to identify a molecularly encoded quiescence cycle, check out the pre-print on bioRxiv! doi: doi.org/10.64898/202...

New short paper from our lab @currentbiology.bsky.social, in which we discover of a new mode of cell motility for choanoflagellates: flagellar gliding. www.cell.com/current-biol... - A 🧵

Flagellar gliding in choanoflagellates
Freire-Delgado and Brunet discover a new mode of cell motility in choanoflagellates, the closest relatives of animals. Under mild confinement, choanoflagellate move over surfaces without cell deformat...

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...

How oncogenic clones can eliminate their neighbours to take over space ? There are different ways combining growth and interfacial tension induced compaction. Check out our latest preprint led by Léo Valon and Alexis Matamoro-Vidal to learn more about this 👇 www.biorxiv.org/content/10.1...

Very happy to share my first story in @levayerr.bsky.social lab, where we show that localized apoptosis drives JNK-dependent developmental delay to ensure global tissue size robustness 🪰
