Dimeric Alix nucleates ESCRT-III CHMP4 polymerization

Nolwenn Miguet, Carlos Contreras‐Martel, Sourav Maity…·Winfríed Weissenhorn

This study shows dimeric Alix nucleates CHMP4 polymerization, essential for ESCRT-III membrane remodeling, and demonstrates that dimerization is required for plasma membrane repair.

Lack of evidence for cargo release of CD63-EVs into recipient cells

Shaghayegh Askarian‐Amiri, Winfríed Weissenhorn, Rémy Sadoul, Christine Chatellard

This study shows that CD63-exosomes do not fuse with recipient cell membranes to release their cargo, challenging the common belief that exosomes deliver molecular cargo via membrane fusion.
