Production of extracellular vesicles in bacteria, particularly outer membrane vesicles (OMVs) in gram-negative bacteria, is a well-documented but poorly understood process. Besides their roles in pathogenesis, cell-to-cell communication, and stress responses, OMVs also play important roles in immunomodulation and balancing the gut microbiota. The review discusses the various roles of OMVs and the current understanding of their biogenesis, as well as the expanding biotechnological applications of OMVs.
Secretion of cellular components across the plasma membrane is an essential process that enables organisms to interact with their environments. Production of extracellular vesicles in bacteria is a well-documented but poorly understood process. Outer membrane vesicles (OMVs) are produced in gram-negative bacteria by blebbing of the outer membrane. In addition to their roles in pathogenesis, cell-to-cell communication, and stress responses, OMVs play important roles in immunomodulation and the establishment and balance of the gut microbiota. In this review, we discuss the multiple roles of OMVs and the current knowledge of OMV biogenesis. We also discuss the growing and promising biotechnological applications of OMV.
