Outer membrane vesicles (blebs) are produced by Escherichia coli , Salmonella , and all other gram-negative bacteria both in vitro and in vivo. Most of the research in the field has focused on the properties of vesicles derived from pathogenic bacteria and their interactions with eukaryotic ...

Use of plasma membrane vesicles
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1980A summary of current methodologies employed to obtain and characterize epithelial plasma membrane vesicles is presented. Particular emphasis is placed on techniques to evaluate such parameters as homogeneity, tightness, orientation, and the percentage of active vesicles in a given vesicular population.

Fusion of photoreceptor membrane vesicles
The Journal of Membrane Biology, 1979The n-alkyl bromides with 6 to 10 carbons induce formation of vesicles of 5 to 100 micrometer diameter from the small vesicles (0.1 micrometer average diameter) produced by disruption of the discs from frog rod photoreceptors. The n-alkanes, n-alkyl iodides and n-alkyl chlorides are relatively ineffective. The formation of large vesicles is independent

The role of membrane vesicles in tumorigenesis
Critical Reviews in Oncology/Hematology, 2011Membrane vesicles are membrane-covered cell fragments generated by all cell types. They comprise a recently recognized new system of intercellular communication, believed to play a pivotal role in information transfer between cells, as they display a large number of biomolecules enclosed within the membrane as well as in the membrane proper.

Sedimentation studies on membrane vesicles
Molecular Biology Reports, 1976Analytical centrifugation was used in order to investigate the size distribution of vesicles in various membrane preparations. Under certain conditions depending among others on the speed of rotation and the temperature, a sedimentation profile was observed that was characteristic for membraneous material.

Roles of bacterial membrane vesicles
Archives of Microbiology, 2014Outer membrane vesicles (OMVs) are released from the outer membrane of Gram-negative bacteria. Moreover, Gram-positive bacteria also produce membrane-derived vesicles. As OMVs transport several bacterial components, especially from the cell envelope, their interaction with the host cell, with other bacteria or as immunogens, have been studied intensely.

The role of coated vesicles in recycling of synaptic vesicle membrane
Cell Biology International Reports, 1989The uptake of extracellular tracers into synaptic nerve terminals has been a phenomenon of persistent interest. Uptake is into synaptic vesicles, hence vesicles spend part of their life in continuity with the plasma membrane, as expected if exocytosis underlies the quantal discharge of neurotransmitters.

Giant Vesicles with Membranous Microcompartments
Langmuir, 2011Incubation of a cell-sized lipid membrane vesicle (giant vesicle, GV) in a diluted aqueous solution of neutral phosphate buffer salts or glucose transformed the GV to an oligovesicular vesicle (OVV) that encapsulates one or more smaller GVs. During the incubation, the membrane of flaccid vesicle invaginated and closed to form the inner vesicle of an ...

Electrophysiology of plasma membrane vesicles
American Journal of Physiology-Renal Physiology, 1984In both renal and gastrointestinal physiology, it has become popular to study epithelial transport phenomena using vesicles isolated from the apical and basolateral cell membranes. Transport in vesicle preparations is usually monitored with radioactive tracers, but more recently attention has been directed to electrophysiological methods.

Lipid vesicles and membrane fusion
Advanced Drug Delivery Reviews, 1999Membrane fusion is essential for cell survival and has attracted a great deal of both theoretical and experimental interest. Fluorescence (de)quenching measurements were designed to distinguish between bilayermerging and vesicle-mixing. Theoretical studies and various microscopic and diffraction methods have elucidated the mechanism of membrane fusion.
