A Dynamic Model of Fusion Pores in Lipid Bilayers [PDF]
Biophysical Journal, 2012 Biological membranes remodel and change shape in processes like endocytosis, exocytosis, hemifusion, and the expansion of fusion pores. Since the length scale of these processes is generally quite small, computational models are needed to resolve the time course of the membrane.

Fusion of biomimetic stealth probes into lipid bilayer cores [PDF]
Proceedings of the National Academy of Sciences, 2009 Many biomaterials are designed to regulate the interactions between artificial and natural surfaces. However, when materials are inserted through the cell membrane itself the interface formed between the interior edge of the membrane and the material surface is not well understood and poorly controlled.

Shape transformations of lipid vesicles by insertion of bulky-head lipids [PDF]
, 2015 Lipid vesicles, in particular Giant Unilamellar Vesicles (GUVs), have been increasingly important as compartments of artificial cells to reconstruct living cell-like systems in a bottom-up fashion.

Supported Lipid Bilayer Formation: Beyond Vesicle Fusion
Langmuir, 2020 Supported lipid bilayers (SLBs) are cell-membrane-mimicking platforms that can be formed on solid surfaces and integrated with a wide range of surface-sensitive measurement techniques. SLBs are useful for unravelling details of fundamental membrane biology and biophysics as well as for various medical, biotechnology, and environmental science ...

Atomic-resolution simulations predict a transition state for vesicle fusion defined by contact of a few lipid tails. [PDF]
PLoS Computational Biology, 2010 Membrane fusion is essential to both cellular vesicle trafficking and infection by enveloped viruses. While the fusion protein assemblies that catalyze fusion are readily identifiable, the specific activities of the proteins involved and nature of the ...

Voltage Sensing in Bacterial Protein Translocation [PDF]
, 2020 The bacterial channel SecYEG efficiently translocates both hydrophobic and hydrophilic proteins across the plasma membrane. Translocating polypeptide chains may dislodge the plug, a half helix that blocks the permeation of small molecules, from its ...

The structural dynamics of the flavivirus fusion peptide-membrane interaction. [PDF]
PLoS ONE, 2012 Membrane fusion is a crucial step in flavivirus infections and a potential target for antiviral strategies. Lipids and proteins play cooperative roles in the fusion process, which is triggered by the acidic pH inside the endosome. This acidic environment
