Subpopulations of extracellular vesicles and their therapeutic potential

Publication date: Available online 16 February 2018 Source:Molecular Aspects of Medicine Author(s): Cecilia Lässer, Su Chul Jang, Jan Lötvall Extracellular vesicles (EVs), such as exosomes and microvesicles, have over the last 10–15 years been recognized to convey key messages in the molecular communication between cells. Indeed, EVs have the capacity to shuttle proteins, lipids, and nucleotides such as RNA between cells, leading to an array of functional changes in the recipient cells. Importantly, the EV secretome changes significantly in diseased cells and under conditions of cellular stress. More recently, it has become evident that the EV secretome is exceptionally diverse, with many different types of EVs being released by a single cell type, and these EVs can be described in terms of differences in density, molecular cargos, and morphology. This review will discuss the diversity of EVs, will introduce some suggestions for how to categorize them, and will propose how EVs and their subpopulations might be used for very different therapeutic purposes.
