This review explores the role of Escherichia coli outer membrane vesicles (OMVs) in bacterial virulence, antibiotic resistance, and host interactions. It evaluates the biogenesis, molecular composition, and potential biomedical applications of OMVs. The review emphasizes the importance of understanding OMVs for developing novel strategies in infection control and therapy.
Abstract
<i>Escherichia coli</i> is a clinically significant Gram-negative pathogen, and the emergence of multidrug-resistant and highly virulent strains poses a grave threat to public health. Outer membrane vesicles (OMVs) are spherical nanostructures secreted by Gram-negative bacteria and composed of the outer membrane and a suite of encapsulated bioactive components, including proteins, lipopolysaccharides, and nucleic acids. Research indicates that OMVs play pivotal roles in pathogenic mechanisms, antimicrobial resistance transmission, and host-pathogen interactions. This review systematically elucidates the biogenesis mechanisms and molecular composition of <i>E. coli</i> OMVs while thoroughly examining their core biological functions in virulence, resistance, and immune modulation. Additionally, this review evaluates the translational potential of OMVs in vaccine development, biomolecular delivery, and tumor therapy. In summary, a comprehensive understanding of the biological properties and functions of <i>E. coli</i> OMVs is crucial for developing innovative OMV-based strategies for infection control, diagnosis, and therapy, thereby providing valuable directions for future research.
Background
Escherichia coli is a significant pathogen due to its multidrug-resistant and highly virulent strains, posing a public health threat. Outer membrane vesicles (OMVs) are secreted by Gram-negative bacteria like E. coli and are involved in various biological processes, including virulence and antibiotic resistance. Understanding the roles of OMVs is crucial for developing innovative strategies for infection control and therapy.
