Release of Outer Membrane Vesicles from Bordetella pertussis
Current Microbiology, 1999 The aim of the study reported here was to investigate the production of Bordetella pertussis outer membrane vesicles (OMVs). Numerous vesicles released from cells grown in Stainer-Scholte liquid medium were observed. The formation of similar vesicle-like structures could also be artificially induced by sonication of concentrated bacterial suspensions ...

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

Dynamic model and stationary shapes of fluid vesicles
, 2006 A phase-field model that takes into account the bending energy of fluid vesicles is presented. The Canham-Helfrich model is derived in the sharp-interface limit. A dynamic equation for the phase-field has been solved numerically to find stationary shapes

Three-dimensional architecture and biogenesis of membrane structures associated with hepatitis C virus replication [PDF]
, 2012 All positive strand RNA viruses are known to replicate their genomes in close association with intracellular membranes. In case of the hepatitis C virus (HCV), a member of the family Flaviviridae, infected cells contain accumulations of vesicles forming ...

The outer membrane vesicles: Secretion system type zero [PDF]
Traffic, 2017 Gram‐negative bacteria have mechanisms through which they can colonize and survive in different environments, such as the secretion systems types (1‐6) that have been widely studied and characterized. Nowadays, some authors have proposed extracellular structures, such as the outer membrane vesicles (OMVs), to be considered as an additional and ...

Visualization of the exocyst complex dynamics at the plasma membrane of Arabidopsis thaliana [PDF]
, 2013 The exocyst complex, an effector of Rho and Rab GTPases, is believed to function as an exocytotic vesicle tether at the plasma membrane before soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex formation.

Vibrio cholerae Outer Membrane Vesicles Inhibit Bacteriophage Infection [PDF]
Journal of Bacteriology, 2018 Phages have been increasingly recognized for the significance of their interactions with bacterial cells in multiple environments. Bacteria use myriad strategies to defend against phage infection, including restriction modification, abortive infection, phase variation of cell surface receptors, phage-inducible chromosomal islands ...

Diffuse interface models of locally inextensible vesicles in a viscous fluid
, 2013 We present a new diffuse interface model for the dynamics of inextensible vesicles in a viscous fluid. A new feature of this work is the implementation of the local inextensibility condition in the diffuse interface context.

Polymer Release out of a Spherical Vesicle through a Pore
, 1998 Translocation of a polymer out of curved surface or membrane is studied via mean first passage time approach. Membrane curvature gives rise to a constraint on polymer conformation, which effectively drives the polymer to the outside of membrane where the

The Pseudomonas Quinolone Signal (PQS): Not Just for Quorum Sensing Anymore
Frontiers in Cellular and Infection Microbiology, 2018 The Pseudomonas quinolone signal (PQS) has been studied primarily in the context of its role as a quorum-sensing signaling molecule. Recent data suggest, however, that this molecule may also function to mediate iron acquisition, cytotoxicity, outer ...
