Types and origins of bacterial membrane vesicles
Nature Reviews Microbiology, 2018Most bacteria release membrane vesicles (MVs) that contain specific cargo molecules and have diverse functions, including the transport of virulence factors, DNA transfer, interception of bacteriophages, antibiotics and eukaryotic host defence factors, cell detoxification and bacterial communication.

Bacterial membrane vesicle functions, laboratory methods, and applications
Biotechnology Advances, 2022Bacterial membrane vesicles (BMVs) are cupped-shaped structures formed by bacteria in response to environmental stress, genetic alteration, antibiotic exposure, and others. Due to the structural similarities shared with the producer organism, they can retain certain characteristics like stimulating immune responses.

Bacterial membrane vesicles as promising vaccine candidates
European Journal of Pharmaceutics and Biopharmaceutics, 2019Both Gram-positive and Gram-negative bacteria can release nano-sized lipid bilayered structures, known as membrane vesicles (MVs). These MVs play an important role in bacterial survival by orchestrating interactions between bacteria and between bacteria and host. The major constituents of MVs are proteins, lipids and nucleic acids.

Immune modulation by bacterial outer membrane vesicles
Nature Reviews Immunology, 2015Gram-negative bacteria shed extracellular outer membrane vesicles (OMVs) during their normal growth both in vitro and in vivo. OMVs are spherical, bilayered membrane nanostructures that contain many components found within the parent bacterium. Until recently, OMVs were dismissed as a by-product of bacterial growth; however, findings within the past ...

Bacterial Nanobioreactors–Directing Enzyme Packaging into Bacterial Outer Membrane Vesicles
ACS Applied Materials & Interfaces, 2015All bacteria shed outer membrane vesicles (OMVs) loaded with a diverse array of small molecules, proteins, and genetic cargo. In this study we sought to hijack the bacterial cell export pathway to simultaneously produce, package, and release an active enzyme, phosphotriesterase (PTE). To accomplish this goal the SpyCatcher/SpyTag (SC/ST) bioconjugation

Bacterial Outer Membrane Vesicles: From Discovery to Applications
Annual Review of Microbiology, 2021Secretion 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.

Circulating Bacterial Membrane Vesicles Cause Sepsis in Rats
Shock, 2012Gram-negative bacteria remain the leading cause of sepsis, a disease that is consistently in the top 10 causes of death internationally. Curing bacteremia alone does not necessarily end the disease process as other factors may cause inflammatory damage.

Transport studies in bacterial membrane vesicles.
Science (New York, N.Y.), 1976The use of bacterial membrane vesicles as an experimental system for the study of active transport has been discussed. Vesicles are prepared from osmotically sensitized bacteria, and consist of osmotically intact, membranebound sacs without internal structure. They retain litle or no cytoplasm.

Proteomics in gram‐negative bacterial outer membrane vesicles
Mass Spectrometry Reviews, 2008AbstractGram‐negative bacteria constitutively secrete outer membrane vesicles (OMVs) into the extracellular milieu. Recent research in this area has revealed that OMVs may act as intercellular communicasomes in polyspecies communities by enhancing bacterial survival and pathogenesis in hosts.

Bacterial bioreactors: Outer membrane vesicles for enzyme encapsulation
2019Bacterial membrane vesicles, whether naturally occurring or engineered for enhanced functionality, have significant potential as tools for bioremediation, enzyme catalysis, and the development of therapeutics such as vaccines and adjuvants. In many instances, the vesicles themselves and the naturally occurring proteins are sufficient to lend ...
