pRIMing synaptic vesicles for fusion

Nature Neuroscience, 2001
A characterization of C. elegans lacking the gene for Rim suggests that this protein may be involved in priming synaptic vesicles for fusion, not in docking or organizing active zones.

Computer Simulation of Vesicle Fusion

Key Engineering Materials, 2011
A dissipative particle dynamics simulation method is used to get insight into molecular-level details of vesicle fusion in this study. For simplicity, the simulation system contains water and amphiphiles. The fusion mechanism is investigated in detail. It is found that the whole fusion process is in well agreement with the “stalk-pore” hypothesis.

The Fusion Between Autophagic Vesicles and Lysosomes

2021
The autophagosome delivers engulfed substrates to the lysosome for degradation via membrane fusion between the autophagosome and the lysosome. The process of membrane fusion is highly conserved in evolution. It is widely accepted that membrane fusion in general is driven by the zippering of the SNARE complex to form a four-helix bundle. Besides SNAREs,

Photocontorollable fusion of lipid vesicles

2015 International Symposium on Micro-NanoMechatronics and Human Science (MHS), 2015
The behavior of lipid vesicles in the presence of a photosensitive surfactant was studied. We found that UV irradiation induces the change in membrane tension and causes the fusion of vesicles. We discuss the physical mechanism of this fusion event in terms of the elastic free energy of the membrane.

SNARE-mediated vesicle navigation, vesicle anatomy and exocytotic fusion pore

Cell Calcium, 2018
The focus of this special issue (SI) »Membrane Merger in Conventional and Unconventional Vesicle Secretion« is regulated exocytosis, a universally conserved mechanism, consisting of a merger between the vesicle and the plasma membranes. Although this process evolved with eukaryotic organisms some three billion years ago (Spang et al., 2015), the ...

DNA-Induced Programmable Fusion of Phospholipid Vesicles

Journal of the American Chemical Society, 2007
In nature, the fusion of phospholipid vesicles is regulated and catalyzed by highly specialized SNARE proteins. A key step in this process is to bring about close apposition of the lipid bilayers that are destined to fuse. Inspired by nature's use of molecular recognition between receptor proteins, we developed a method to force bilayers into proximity

Stability and Fusion of Vesicles

1980
Amphiphilic molecules, when put into water solutions, build up organized structures so as to shield their hydrophobic parts from the water molecules.

Linking synaptotagmin to vesicle fusion

2012
Synaptotagmin 1 is an integral synaptic vesicle protein and is believed to be the major calcium sensor in synaptic vesicle fusion. Loss of synaptotagmin 1 from the nematode C. elegans results in an uncoordinated phenotype and decreased levels of neurotransmitter release.
