Cover Story: Extracellular vesicles (EVs) are lipid bilayered, nanoscale structures that are released into the extracellular space by living cells and, thus, represent a bona fide secretion system. In bacteria, the study of EVs’ composition, biogenesis mechanisms, biological roles, and possible biotechnological applications have recently become hot topics. Here, we present a general overview of the most relevant findings in EVs released by Gram-negative bacteria, focusing our attention on bacteria from the phylum Cyanobacteria, in which the study of EVs has been largely overlooked. As Cyanobacteria are important primary producers with unique cell wall features, future studies in cyanobacterial EVs may shed light on several pending aspects of EV biology, as well as clarify unsolved traits of cyanobacterial physiology.
