Therapeutics: Helping vesicles to deliver drugs inside cells An increased understanding of how extracellular vesicles (EVs) enter cells and deliver molecules will enable promising new therapies, according to researchers in the Netherlands, UK and France. EVs are liquid-filled sacs secreted by cells that transport proteins, lipids and RNA between cells, and therefore have potential for delivering drugs. Pieter Vader at UMC Utrecht and co-workers review recent research into EVs, focusing on how EVs are distributed around the body, and how they target and enter cells. However, there is little known about EV biology once they are inside cells, and it is likely that many EVs simply degrade without delivering their cargo. Further research in this area could help identify features that improve cargo escape from EVs, thus ensuring that future therapies can be effective.
