Electrostimulated fusion and fission of bilayer lipid membranes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1983
Abstract The interaction and fusion of black lipid membranes have been studied. Two planar bilayers were simultaneously inflated towards each other; when they made contact, spontaneous formation of a ‘trilaminar structure’ (one bilayer bounded by two bilayers along the perimeter) was observed.

The Lipid Bilayer, Mechanisms of Fusion and Transmembrane Transport

1981
DR. CULLIS: Fusion is among the most important events that takes place in the cytoplasm including, for example, the blebbing off of various secretory granules to fuse with the membrane surface, the fusion processes involved in interorganelle transport, the virus blebbing off process, on endocytotic processes, such as occur for coated vesicles, which ...

The interaction and fusion of bilayers formed from unsaturated lipids

European Biophysics Journal, 1991
The interactions between unsaturated phospholipid bilayers deposited on mica were measured in aqueous solution using a surface forces apparatus. The bilayers were made of L-alpha-dioleoylphosphatidyl-choline (DOPC), L-alpha-dioleoylphosphatidyl ethanolamine (DOPE), and mixtures of the two, and were formed on mica by Langmuir-Blodgett deposition after ...

Reaction characteristics and mechanisms of lipid bilayer vesicle fusion

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1984
Abstract Small unilamellar lipid bilayer vesicles were prepared from brain phosphatidylserine, egg phosphatidylcholine, and synthetic dipalmitoylphosphatidylcholine, and were fused into larger structures by freezing and thawing, addition of calcium chloride, and passage through the lipid phase transition temperature.

Target-selective vesicle fusion induced by molecular recognition on lipid bilayers

Chem. Commun., 2009
A novel programmable membrane fusion system driven by selective molecular recognition between diols and boronic acids on the different vesicles was constructed in this study.

Serotonin Promotes Vesicular Association and Fusion by Modifying Lipid Bilayers

The Journal of Physical Chemistry B
AbstractThe primary event in chemical neurotransmission involves the fusion of a membrane-limited vesicle at the plasma membrane and the subsequent release of its chemical neurotransmitter cargo. The cargo itself is not known to have any effect on the fusion event. However, amphiphilic monoamine neurotransmitters (e.g. serotonin and dopamine) are known

Fusion of Lipid Vesicles with Planar Lipid Bilayers Induced by a Combination of Peptides

Langmuir, 2011
We studied the peptide-induced membrane fusion process between small unilamellar vesicles (SUVs) and supported planar bilayers (SPBs) with the aim of developing a method for incorporating membrane components into SPBs. As fusogenic peptides, two analogues of the N-terminal region of an influenza membrane fusion protein hemaggulutinin, anionic E5 and ...

Fusion of lipid bilayers induced by synthetic lipids and peptides

2009
The fusion-inducing properties of three different synthetic lipid derivatives were investigated in model membranes. The results are discussed in terms of membrane destabilization caused by the formation of non-bilayer lipid structures following charge neutralization of the fusogenic components. First, studies on the fusion of large unilamellar vesicles

Protein-mediated intermembrane contact facilitates fusion of lipid vesicles with planar bilayers

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1984
Fusion of phospholipid vesicles with planar bilayer membranes occurs provided there is an intermembrane contact, which can be mediated by phospholipid-binding proteins, even in the absence of calcium. The firm attachment phase is then followed by the osmotically-driven fusion.

pH-dependent Self-association of Influenza Hemagglutinin Fusion Peptides in Lipid Bilayers

Journal of Molecular Biology, 2000
We have recently designed a host-guest peptide system that allows us to quantitatively measure the energetics of interaction of viral fusion peptides with lipid bilayers. Here, we show that fusion peptides of influenza hemagglutinin reversibly associate with one another at membrane surfaces above critical surface concentrations, which range from one to
