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

Production of Outer Membrane Vesicles and Outer Membrane Tubes by Francisella novicida [PDF]

Journal of Bacteriology, 2012
Francisella spp. are highly infectious and virulent bacteria that cause the zoonotic disease tularemia. Knowledge is lacking for the virulence factors expressed by Francisella and how these factors are secreted and delivered to host cells. Gram-negative bacteria constitutively release outer membrane vesicles (OMV), which may function in the delivery of

The Xylella fastidiosa PD1063 protein is secreted in association with outer membrane vesicles.

PLoS ONE, 2014
Xylella fastidiosa is a gram-negative, xylem-limited plant pathogenic bacterium that causes disease in a variety of economically important agricultural crops including Pierce's disease of grapevines.

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.

A novel mechanism for the biogenesis of outer membrane vesicles in Gram-negative bacteria

Nature Communications, 2016
Bacteria release outer membrane vesicles (OMVs) that play important roles in pathogenesis and intercellular interactions. Here, Roier et al. provide evidence supporting that phospholipid accumulation in the outer leaflet of the outer membrane ...

Regulation of outer-membrane proteins (OMPs) A and F, during hlyF-induced outer-membrane vesicle (OMV) biosynthesis

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

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.

A morphological view on mitochondrial protein targeting [PDF]

, 1994
Mitochondrial protein targeting includes both intramitochondrial sorting of proteins encoded by the organellar genome and import and subsequent sorting of nuclear encoded precursor proteins. Only a few proteins are encoded by the mitochondrial genome and

Photoreceptor Outer Segment-like Structures in Long-Term 3D Retinas from Human Pluripotent Stem Cells. [PDF]

, 2017
The retinal degenerative diseases, which together constitute a leading cause of hereditary blindness worldwide, are largely untreatable. Development of reliable methods to culture complex retinal tissues from human pluripotent stem cells (hPSCs) could ...

Sites of Biosynthesis of Outer and Inner Membrane Proteins of Neurospora crassa Mitochondria [PDF]

, 1970
Outer and inner membranes of Neurospora crassa mitochondria were separated by the combined swelling, shrinking, sonication procedure. Membranes were characterized by electron microscopy and by marker enzyme activities.
