Vimentin intermediate filaments support autophagosome biogenesis at ER-endosomes contact sites in response to starvation

Macroautophagy (autophagy) is a fundamental catabolic process requiring the biogenesis of the autophagosome to support cell survival during stress. While the roles of F-actin and microtubule cytoskele...

We’re excited to announce the opening of the Geneva Expansion Microscopy Facility (GenExM)! GenExM is a full-service U-ExM platform (U-ExM, Cryo-ExM, iU-ExM), delivering nanoscale imaging. Led by Dr. Olivier Mercey, GenExM welcomes academic & industrial collaborations. 👉 www.unige.ch/genexm/

very exciting new set of data from @membramics-lab.bsky.social on vimentin in autophagosome biogenesis regulation: bravo @frengerquentin.bsky.social !

Quentin Frenger@frengerquentin.bsky.social · 8mo ago

My first postdoc preprint is out! Upon starvation, the Vimentin IFs network rapidly compacts (in <15 min!) to "cage" ER-Endosome membrane contact sites. This spatial confinement is crucial for autophagosome biogenesis. www.biorxiv.org/content/10.6... #CellBiology #Autophagy #Vimentin
