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 ...

Neutralization of Neisseria meningitidis outer membrane vesicles
Inflammation Research, 2011We aimed to determine the neutralization of Neisseria meningitidis outer membrane vesicles (blebs) by humoral and cellular elements of whole blood.The interaction of FITC-labeled blebs with monocytes was studied by spectrofluorometry. Blebs are able to induce an oxidative burst in neutrophils, and we evaluated the inhibitory effect of plasma on this ...

Biogenesis of Outer Membrane Vesicles
2012The different steps involved in the formation and release of outer membrane vesicles (OMVs) from the parent bacteria as revealed by the experimental evidence and derived models presented by different investigators are discussed. An attempt has been made to develop a unified concept of the biogenesis of OMVs released by different Gram-negative bacteria.

Acinetobacter baumannii outer membrane protein a modulates the biogenesis of outer membrane vesicles
The Journal of Microbiology, 2012Acinetobacter baumannii secretes outer membrane vesicles (OMVs) during both in vitro and in vivo growth, but the biogenesis mechanism by which A. baumannii produces OMVs remains undefined. Outer membrane protein A of A. baumannii (AbOmpA) is a major protein in the outer membrane and the C-terminus of AbOmpA interacts with diaminopimelate of ...

Purification of Borrelia burgdorferi Outer Membrane Vesicles
Bacterial outer membrane vesicles (OMVs) are spherical membrane constructs shed by gram-negative bacteria. OMVs produced by the Lyme disease pathogen Borrelia burgdorferi have been identified to contain such virulence factors as OspA, OspB, OspC, and genetic material.Hanna, Tammisto, Kati, Karvonen

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.

Isolation of Outer Membrane Vesicles from Helicobacter pylori
2021Outer membrane vesicles (OMV) shed by pathogenic bacteria have multifunctional roles in disease initiation and progression. Further, their efficacy as novel vaccines has underscored their importance as potential therapeutics. Consequently, to advance allied research related to their immunogenicity and pathogenicity it is important to separate these ...

Outer membrane vesicles as acellular vaccine against pertussis
Vaccine, 2008In this study the development and evaluation of outer membrane vesicles (OMVs) obtained from Bordetella pertussis as vaccines against pertussis disease is described. SDS-PAGE, immunoblot techniques and gel electrophoresis associated to tandem mass spectrometry were used to describe the composition of the OMVs obtained from B.

Outer Membrane Vesicles: Physiological Medical Applications
2012Outer membrane vesicles (OMVs) produced by Gram-negative bacteria exhibit enormous functional diversity depending on the bacterial species and environmental niche: these have enabled various physiological roles for these vesicles to play and at the same time OMVs have found important medical applications.
