What would happen if cells would express more molecular motors ?
They would break all microtubules 😱

A molecular-resolution look into the near-native architecture of the spinach chloroplast🌱. This one was a long time in the oven, but we're happy to finally share our "version of record". What long-standing debates did we settle? Check back for a short thread🧵 on Monday. #TeamTomo #PlantScience 🧪🧶🧬🔬🌾

🌱 Using ‘compelling’ methods, including #CryoET, researchers mapped spinach thylakoid membranes at single-molecule precision, revealing how photosynthetic complexes are organised and settling long-standing debates on chloroplast architecture.

Our new paper is out in @currentbiology.bsky.social! Using 3D reconstructions and volume measurements in Drosophila wing primordia, we show that growth can be uncoupled from cell proliferation and uncover a new time window for growth arrest.

A switch to non-proliferative growth sustains Drosophila wing development during the early pupal stage

Using precise tissue volume quantification, El Marzkioui, Gaugué, et al. show that wing primordia continue to grow during the early pupal stage, a phase of increased cell volume driven by insulin/IGF ...

Very proud to share our latest preprint: postdoc/LRSF fellow Yue Rui studies the mechanisms regulating attachment of the cell wall to the plasma membrane. The Cellulose Synthase Complex and REMORINs determine the extent of attachment and root osmotic stress tolerance. www.biorxiv.org/content/10.1...

One protein, two opposing roles: This ‘compelling’ study shows how the same signalling molecule can drive either protrusion or retraction in migrating cells depending on its concentration and activation dynamics.

Belyantseva and Liu et al. report that taperin encircles and stabilizes F-#actin at auditory hair cell #stereocilia bases and bundles F-actin. Taperin deficiency causes stereocilia disassembly, rootlet breakage at pivots, and other abnormalities culminating in deafness. rupress.org/jcb/article/...

Nature research paper: Dynamic cytoskeletal regulation of cell shape supports resilience of lymphatic endothelium

https://go.nature.com/4hrHX0v

Dynamic cytoskeletal regulation of cell shape supports resilience of lymphatic endothelium - Nature

Dynamic cytoskeletal regulation of lymphatic endothelial cell shape, induced by isotropic stretch and crucial for dermal lymphatic capillary function, is identified and found to result from continuous remodelling of cellular overlaps that maintain vessel integrity.

It’s incredibly hard to study lipids in biological membranes on the nanoscale. You need near-perfect information on both membrane ultrastructure and lipid density, which usually isn’t attainable. Lipid-CLEM brought to you by @mathilda95.bsky.social changes that.
