Towards a unified framework for the function of endoplasmic reticulum exit sites
Nature Reviews Molecular Cell Biology, Published online: 29 September 2025; doi:10.1038/s41580-025-00899-0Endoplasmic reticulum exit sites (ERES) are specialized ER subdomains that regulate the export of secreted cargo. This Roadmap explores how ERES integrate biochemical and mechanical signals to coordinate trafficking and proposes a multidisciplinary strategy to investigate their function, including in disease.

🌱✂️ How do plant cells decide where to divide? Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.

On April 19, 1898, Camillo Golgi described what we now know as the
#Golgi
apparatus - a structure so pretty and unusual it took over fifty years for the scientific community to agree it wasn’t just an artefact. April 19 is

It's hard to believe, but... The plant ERGIC has finally been partially elucidated. 👍 A completely new vision of the ER-Golgi interface that remains to be explored. 🔬👋

Great collaboration with
@yvonjaillais.bsky.social
🌱 Plants use membrane contact sites (MCS) for cell-to-cell signaling! ➡️ MCTP tethers & PI4P regulate ER-PM contacts in plasmodesmata, impacting trafficking. ➡️ MCS roles span intra- and intercellular communication.

Plasmodesmata act as unconventional membrane contact sites regulating intercellular molecular exchange in plants
Plant intercellular communication is regulated via tubular ER-PM membrane contact through PI4P and MCTP protein tethers.
