Very excited to be sharing our new paper, just out in Nature Cell Biology! The big question we investigate: How do migrating cells put their front 🔴 and back 🔵 in the right place?
1 week to start🔥 New @focalplane.bsky.social webinar series focused on #CellMigration, register & join us▶️, it will be fun! pls spread the word, in the next one, ECRs could apply to show their work ;) ▶️ to register: focalplane.biologists.com/2026/05/29/n... @dgz.bsky.social @the-node.bsky.social
Our June issue is here! rupress.org/jcb/issue/22... The cover shows a maximum intensity projection from a confocal image stack showing an angiogenic sprout emerging from an engineered microvessel. From @lakynm.bsky.social et al. of the Matthew Kutys lab: rupress.org/jcb/article/... #Cytoskeleton
Saishree S. Iyer and Anna Akhmanova @utrechtuniversity.bsky.social review the mechanisms controlling plus-end elongation of centriolar and ciliary #microtubules, revealing shared principles. rupress.org/jcb/article/... #Centrioles #Cilia #Cytoskeleton
Vote for @marcoenriquez18.bsky.social #FocalPlane entry ‘Fibroblasts & ECM’ it is a beautiful representation of his passion- cells & polymers 🥰.
Registration open for the @garvaninstitute.bsky.social Signalling Symposium. linktr.ee/garvansignal...
A day in the life of a growing hiPSC spheroid expressing endogenously mStayGold-tagged histone 3.3 for #FluorescenceFriday and the #Snouty aficionados. 28 hours (and >50,000 exposures) later and they are still going! Home-brewed volume projection.

Over the past decade, colchicine has re-emerged as a promising therapeutic candidate for atherosclerotic cardiovascular disease. Here we review evidence from large randomized controlled trials together with advances in mechanistic research that have clarified how colchicine modulates vascular inflammation and plaque stability. Canonically, colchicine disrupts microtubule dynamics and suppresses NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation. Beyond these actions, it limits oxidative stress, modulates cytoskeletal cross-talk, attenuates cholesterol crystal formation and reprograms inflammatory and metabolic proteomic networks. Colchicine influences multiple vascular and immune cell types, including neutrophils, monocytes, macrophages, endothelial cells, smooth muscle cells and platelets, collectively reducing vascular inflammation and promoting plaque stability. Notably, while colchicine has demonstrated benefit in coronary artery disease, several rec

Discovery Projects (DP27) still won’t be announced until mid–late Jan. 2027, i.e. 13 months after EOI submission! Similarly, Laureate F’ships – 11 months. However, gladly, Future Fellowships (FT26) will 9 months (back to “normal”).
