MOREL Lab / MEMBRAMICS research

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.

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

don't forget the @sbcf.bsky.social special symposium on #eukaryogenesis!

we have available slots for oral presentation

Etienne @membramics-lab.bsky.social is very happy to visit @rouxlab.bsky.social in Geneva! great people, great projects, good memories...

FEBS Press Phosphoinositides are dynamic lipids at the heart of cellular stress adaptation. By reshaping membranes, controlling organelles' morphodynamics, driving traffic inside the cell, and even supporting D....

very proud of @frengerquentin.bsky.social for his best oral presentation at European Intermediate Filaments 2025 congress! welldone Quentin! 👍

you still have this picture! 😍

my 78 (strat 😅) is still perfect!

no PRS anymore? 😘

@membramics-lab.bsky.social lab is in the spotlight at @inem-necker.bsky.social with a showcase of scientific photos from our researchers!

impressive piece of work @nadlerlab.bsky.social ! congrats!

Endosome–ER contact sites in phagophore formation Autophagy is a crucial ‘self-eating’ mechanism used by eukaryotic cells to degrade and recycle cytosolic materials. A recent study by Da Graça et al. reports that the dynamic mobilization of endosome–...

soon your own ATG16L1 story @frengerquentin.bsky.social !

This work illustrates the importance of Rab11 membranes rewiring in response to viral stress, and the key role of PI3P/PI4P turnover in membrane reprogramming during cellular hijacking by the Influenza virus

huge congrats to @carlaalemany.bsky.social & @julianedagraca.bsky.social and collaborators!

(again!) new publication for @membramics-lab.bsky.social, by @carlaalemany.bsky.social & @julianedagraca.bsky.social

in collaboration with N Naffakh & JB Brault, we show that Influenza virus triggers an ATG16L1/Rab11 PI4P response at ER membrane for viral export

journals.plos.org/plosbiology/...

In details, we show that upon starvation, EERCS transiently stabilize at the omegasomal membrane and ER-exit sites, promoting local Ca²⁺ release and phase transition. Within EERCS confined interspace, Rab3A nanovesicles undergo homo-fusion, mediated by RAB3GAP, driving proto-phagophore assembly.

New publication by @julianedagraca.bsky.social @membramics-lab.bsky.social

We show that ER–endosome contact sites (EERCS) are essential for autophagosome biogenesis by creating a specialized environment in response to starvation.

👏🏼 Proud to see @julianedagraca.bsky.social, former PhD student at INEM, honored with the 2025 Beth Levine Thesis Prize for her outstanding work on autophagy, supervised by Etienne Morel @membramics-lab.bsky.social.

congrats (again) to @julianedagraca.bsky.social !

Master students farewell (we will miss you 🥲) and team-sport performing at #coursedesprincesses for @membramics-lab.bsky.social summer start!

(bravo Aurore, Laura R, Laura S, Dobrawa, Carla and even Juliane!)

@membramics-lab.bsky.social lab, summer version 😗

dear all! The Membrane Band (www.membraneband.com) will give a concert for the 30th Anniversary of the "Cell biology & Cancer Research Unit" (aka UMR144 for close friends) ‪of Curie Institute on Monday 23th fo June! @institutcurie.bsky.social

see you there?

Today was about celebrations! @julianedagraca.bsky.social spent the day in the lab, and we celebrated TWO accepted papers (...more news to come 😉...).

@membramics-lab.bsky.social is a lovely team, for sure.

huge congrats to our beloved @carlaalemany.bsky.social & @julianedagraca.bsky.social 🥲

yesterday, thanks to @delevoyecedric.bsky.social our lab had the chance to spend several hours with Mickey Marks to discuss about... membranes! great day for Science ✌️
