Extracellular vesicles are nanosized membrane vesicles which contain bioactive proteins, lipids, metabolites and nucleic acids, and can travel to distant tissues to influence various physiological and pathological functions. Many departments at Belgian universities are witnessing a steady increase in extracellular vesicle research. This creates a unique opportunity to establish a research network with the aim of catalyzing inter- and intra-university collaborations. We therefore launch the Belgian Society for Extracellular Vesicles (BESEV).
