Heliyon, 2019 Background: Gram-negative bacteria actively secrete outer membrane vesicles into the surrounding environment and these vesicles have been shown to play various physiological and protective roles such as carrying antibiotic-degrading enzymes and acting as

Budding and vesiculation induced by conical membrane inclusions [PDF]
, 2009 Conical inclusions in a lipid bilayer generate an overall spontaneous curvature of the membrane that depends on concentration and geometry of the inclusions. Examples are integral and attached membrane proteins, viruses, and lipid domains.

Dynamical regimes and hydrodynamic lift of viscous vesicles under shear [PDF]
, 2009 The dynamics of two-dimensional viscous vesicles in shear flow, with different fluid viscosities $\eta_{\rm in}$ and $\eta_{\rm out}$ inside and outside, respectively, is studied using mesoscale simulation techniques. Besides the well-known tank-treading

Knockout of mlaA increases Escherichia coli virulence in a silkworm infection model.
PLoS ONE, 2022 The mlaA gene encodes a lipoprotein to maintain an outer membrane lipid asymmetry in gram-negative bacteria. Although the role of mlaA in bacterial virulence has been studied in several bacterial species, there are no reports of its role in E.

Porphyromonas gingivalis Outer Membrane Vesicles Increase Vascular Permeability [PDF]
Journal of Dental Research, 2020 Periodontitis is increasingly associated with increased risk of cardiovascular and other systemic diseases. The Gram-negative anaerobe, Porphyromonas gingivalis, is a key periodontal pathogen, and several lines of evidence link the presence of this bacterium in the circulation with vascular disease.

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.

How Well Can You Tailor the Charge of Lipid Vesicles? [PDF]
, 2019 Knowledge and control of surface charge or potential is important for tailoring colloidal interactions. In this work, we compare widely used zeta potential (ζ) measurements of charged lipid vesicle surface potential to direct measurements using the ...

Engineering Planar Gram-Negative Outer Membrane Mimics Using Bacterial Outer Membrane Vesicles
Langmuir, 2023 AbstractAntibiotic resistance is a major challenge in modern medicine. The unique double membrane structure of gram-negative bacteria limits the efficacy of many existing antibiotics and adds complexity to antibiotic development by limiting transport of antibiotics to the bacterial cytosol. New methods to mimic this barrier would enable high-throughput
