Biogenesis of bacterial membrane vesicles [PDF]

Molecular Microbiology, 2009
SummaryMembrane vesicle (MV) release remains undefined, despite its conservation among replicating Gram‐negative bacteria both in vitro and in vivo. Proteins identified in Salmonella MVs, derived from the envelope, control MV production via specific defined domains that promote outer membrane protein–peptidoglycan (OM–PG) and OM protein–inner membrane ...

Membrane Vesicle Production as a Bacterial Defense Against Stress

Frontiers in Microbiology, 2020
Membrane vesicles are the nano-sized vesicles originating from membranes. The production of membrane vesicles is a common feature among bacteria. Depending on the bacterial growth phase and environmental conditions, membrane vesicles show diverse ...

Biophysical Characterization of Membrane Phase Transition Profiles for the Discrimination of Outer Membrane Vesicles (OMVs) From Escherichia coli Grown at Different Temperatures

Frontiers in Microbiology, 2020
Dynamic Light Scattering (DLS), Small Angle X-ray Scattering (SAXS) and Transmission Electron Microscopy (TEM) are physical techniques widely employed to characterize the morphology and the structure of vesicles such as liposomes or human extracellular ...

Bacterial outer membrane vesicle-based cancer nanovaccines

Cancer Biology & Medicine, 2022
Tumor vaccines, a type of personalized tumor immunotherapy, have developed rapidly in recent decades. These vaccines evoke tumor antigen-specific T cells to achieve immune recognition and killing of tumor cells. Because the immunogenicity of tumor antigens alone is insufficient, immune adjuvants and nanocarriers are often required to enhance anti-tumor

The Contribution of Membrane Vesicles to Bacterial Pathogenicity in Cystic Fibrosis Infections and Healthcare Associated Pneumonia

Frontiers in Microbiology, 2020
Almost all bacteria secrete spherical membranous nanoparticles, also referred to as membrane vesicles (MVs). A variety of MV types exist, ranging from 20 to 400 nm in diameter, each with their own formation routes.

Emerging Roles of Extracellular Vesicles in Pneumococcal Infections: Immunomodulators to Potential Novel Vaccine Candidates

Frontiers in Cellular and Infection Microbiology, 2022
The Gram-positive bacterial pathogen, Streptococcus pneumoniae is a major global health threat that kills over one million people worldwide. The pneumococcus commonly colonizes the nasopharynx asymptomatically as a commensal, but is also capable of ...

In situ imaging of bacterial outer membrane projections and associated protein complexes using electron cryo-tomography

eLife, 2021
The ability to produce outer membrane projections in the form of tubular membrane extensions (MEs) and membrane vesicles (MVs) is a widespread phenomenon among diderm bacteria.

Bacterial communication through membrane vesicles [PDF]

Bioscience, Biotechnology, and Biochemistry, 2019
ABSTRACT Bacteria can communicate through diffusible signaling molecules that are perceived by cognate receptors. It is now well established that bacterial communication regulates hundreds of genes. Hydrophobic molecules which do not diffuse in aqueous environments alone have been identified in bacterial communication, that raised the ...

Membrane vesicle-mediated release of bacterial RNA [PDF]

Scientific Reports, 2015
AbstractMany Gram-negative bacterial species release outer membrane vesicles (OMVs) that interact with the host by delivering virulence factors. Here, we report for the first time that RNA is among the wide variety of bacterial components that are associated with OMVs. To characterize the RNA profiles of bacterial OMVs, we performed RNA deep sequencing
