Inhibitors of Bacterial Extracellular Vesicles
Frontiers in Microbiology, 2022 Both Gram-positive and Gram-negative bacteria can secrete extracellular vesicles (EVs), which contain numerous active substances. EVs mediate bacterial interactions with their hosts or other microbes.

Microbial biosynthesis of designer outer membrane vesicles [PDF]
Current Opinion in Biotechnology, 2014 Outer membrane vesicles (OMVs) are nanoscale proteoliposomes that are ubiquitously secreted by Gram-negative bacteria. Interest in these bioparticles has escalated over the years, leading to discoveries regarding their composition, production, and vaccine potential.

Gram-Negative Bacteria’s Outer Membrane Vesicles
Infection & Chemotherapy, 2023 Outer membrane vesicles (OMVs) are spherical bilayered nanoparticles derived from the outer layer of Gram-negative bacteria. Bacteria communicate with nearby bacteria, their environment, and the cells of their host by secreting OMVs, which are essential for their survival.

Contribution of bacterial outer membrane vesicles to innate bacterial defense
BMC Microbiology, 2011 Background Outer membrane vesicles (OMVs) are constitutively produced by Gram-negative bacteria throughout growth and have proposed roles in virulence, inflammation, and the response to envelope stress.

The structure of the COPII transport-vesicle coat assembled on membranes
eLife, 2013 Coat protein complex II (COPII) mediates formation of the membrane vesicles that export newly synthesised proteins from the endoplasmic reticulum. The inner COPII proteins bind to cargo and membrane, linking them to the outer COPII components that form a

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Outer membrane vesicles as platform vaccine technology [PDF]
Biotechnology Journal, 2015 AbstractOuter membrane vesicles (OMVs) are released spontaneously during growth by many Gram‐negative bacteria. They present a range of surface antigens in a native conformation and have natural properties like immunogenicity, self‐adjuvation and uptake by immune cells which make them attractive for application as vaccines against pathogenic bacteria ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
