Research overview
Extracellular vesicles (EVs) had been described as a next-generation drug delivery system, due to the compelling evidence that they can facilitate the transfer of a variety of biomolecules between cells. The identified scaffold protein PLXNA1 showed great potential in developing therapeutic EVs.
Key findings
Extracellular vesicles (EVs) had been described as a next-generation drug delivery system, due to the compelling evidence that they can facilitate the transfer of a variety of biomolecules between cells.
The most frequently used strategy for loading protein cargoes is the endogenous engineering of EVs through genetic fusion of the protein of interest (POI) and scaffold proteins with high EV-sorting ability.
However, the lack of scaffold proteins had become a major issue hindering the promotion of this technology.
Herein, we proposed novel screening criteria that relax the inclusion requirement of candidate scaffold proteins and eventually identified a new scaffold protein, PLXNA1.
