Autonomous movement of chemically powered vesicle [PDF]
Phys. Rev. E 92, 042703 (2015), 2015 A mechanism for self propulsion of deformable vesicle has been proposed, vesicle moves by sensing the self-generated chemical gradient. Like many molecular motors they suffer strong perturbations from the environment in which they move as a result of thermal fluctuations and do not rely on inertia for their propulsion.

Double-mode relaxation of highly deformed vesicles [PDF]
Phys. Rev. E 102, 010605 (2020), 2020 Lipid vesicles are known to undergo complex conformational transitions, but it remains challenging to systematically characterize non-equilibrium membrane shape dynamics. Here, we report the direct observation of lipid vesicle relaxation from highly deformed shapes using a Stokes trap.

Extracellular vesicle isolation and characterization: toward clinical application.
Journal of Clinical Investigation, 2016 Two broad categories of extracellular vesicles (EVs), exosomes and shed microvesicles (sMVs), which differ in size distribution as well as protein and RNA profiles, have been described.

Microbiological Reviews, 1975 The gas vesicle is a hollow structure made of protein. It usually has the form of a cylindrical tube closed by conical end caps. Gas vesicles occur in five phyla of the Bacteria and two groups of the Archaea, but they are mostly restricted to planktonic microorganisms, in which they provide buoyancy.

C-terminal calcium binding of α-synuclein modulates synaptic vesicle interaction
Nature Communications, 2018 Alpha-synuclein is known to bind to small unilamellar vesicles (SUVs) via its N terminus, which forms an amphipathic alpha-helix upon membrane interaction.

Smectic Polymer Vesicles [PDF]
Soft Matter 5 (2009) 3446-3451, 2009 Polymer vesicles are stable robust vesicles made from block copolymer amphiphiles. Recent progress in the chemical design of block copolymers opens up the exciting possibility of creating a wide variety of polymer vesicles with varying fine structure, functionality and geometry.

Frontiers in Synaptic Neuroscience, 2019 The connection strength of most chemical synapses changes dynamically during normal use as a function of the recent history of activity. The phenomenon is known as short-term synaptic plasticity or synaptic dynamics, and is thought to be involved in ...

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2002 We present a method to control the osmotic stress of giant unilamellar vesicles (GUV) and we report an original shrinkage mode of the vesicles: the volume reduction is accompanied by the formation of inverted daughter vesicles which gives the shrunk vesicles the appearance of raspberries.

Frontiers in Immunology, 2018 Extracellular vesicles (EVs) are responsible for a multitude of physiological functions, including immunomodulation. A heterogenous mixture of small EV (sEV) subsets, including putative exosomes, is derived when commonly used “exosome” isolation ...

Tetraspanins in Extracellular Vesicle Formation and Function
Frontiers in Immunology, 2014 Extracellular vesicles (EVs) represent a novel mechanism of intercellular communication as vehicles for intercellular transfer of functional membrane and cytosolic proteins, lipids, and RNAs.
