Bacterial membrane vesicles in inflammatory bowel disease
Life Sciences, 2022Inflammatory bowel disease (IBD) is characterized by chronic intestinal inflammation with no cure. The intestine is fundamental in controlling human health. Disruption of the microbial ecosystem in the intestine is considered an important cause of IBD.

Roles of bacterial membrane vesicles
Archives of Microbiology, 2014Outer membrane vesicles (OMVs) are released from the outer membrane of Gram-negative bacteria. Moreover, Gram-positive bacteria also produce membrane-derived vesicles. As OMVs transport several bacterial components, especially from the cell envelope, their interaction with the host cell, with other bacteria or as immunogens, have been studied intensely.

The role of bacterial membrane vesicles in antibiotic resistance
Annals of the New York Academy of Sciences, 2022Abstract Bacterial survival during antibiotic exposure is a complex and multifaceted phenomenon. On top of antibiotic resistance genes, biofilm formation, and persister tolerance, bacterial membrane vesicles (MVs) provide a layer of protection that has been largely overlooked.

Immunomodulatory roles and novel applications of bacterial membrane vesicles
Molecular Immunology, 2021Bacteria release extracellular vesicles (EVs) known as bacterial membrane vesicles (BMVs) during their normal growth. Gram-negative bacteria produce BMVs termed outer membrane vesicles (OMVs) that are composed of a range of biological cargo and facilitate numerous bacterial functions, including promoting pathogenesis and mediating disease in the host ...

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 ...

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.

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

Active Transport of Solutes in Bacterial Membrane Vesicles
1977Publisher Summary The metabolic energy-dependent processes are thought to be the major bacterial mechanisms involved in the accumulation of solute in the cytoplasm. The two processes differ in an important aspect: in group translocation, the transported molecule is changed covalently during passage through the membrane, while in active transport the ...

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 ...
