Abstract:
The release of cellular factors by means of extracellular vesicles (EVs) is conserved in archaea, bacteria, and eukaryotes. EVs are released by growing bacteria as part of their interaction with their environment and, for pathogenic bacteria, constitute an important component of their interactions with the host. While EVs released by gram-negative bacteria have been extensively studied, the vesicles released by thick cell wall microorganisms like mycobacteria were recognized only recently and are less well understood. Nonetheless, studies of mycobacterial EVs have already suggested roles in pathogenesis, opening exciting new avenues of research aimed at understanding their biogenesis and potential use in antitubercular strategies. In this minireview, we discuss the discovery of mycobacterial vesicles, the current understanding of their nature, content, regulation, and possible functions, as well as their potential therapeutic applications.

Exocytosis
Exocytosis is the opposite of endocytosis, which brings molecules inside the cell. Sometimes, the released materials are signaling molecules. For example, neurons typically use exocytosis to release neurotransmitters. Cells also use exocytosis to insert proteins such as ion channels into their cell membranes, secrete proteins for use in the extracellular matrix, or...
