Exosome secretion: beyond simple membrane fusion
In an article published in the Journal of Extracellular Vesicles, scientists show that the release of exosomes—extracellular vesicles that enable the removal of cellular waste and communication between cells—is more complex than previously thought. They demonstrate the involvement of two enzymes that cleave proteins involved in anchoring exosomes to the cell membrane. Because the activity of these enzymes is finely modulated, this discovery opens new...
