Influenza A matrix protein M1 induces lipid membrane deformation via protein multimerization [PDF]

, 2019
The matrix protein M1 of the Influenza A virus (IAV) is supposed to mediate viral assembly and budding at the plasma membrane (PM) of infected cells. In order for a new viral particle to form, the PM lipid bilayer has to bend into a vesicle toward the ...

Interaction of apolipoprotein A-I in three different conformations with palmitoyl oleoyl phosphatidylcholine vesicles

Journal of Lipid Research, 2002
Interactions of apolipoprotein A-I (apoA-I) with cell membranes appear to be important in the initial steps of reverse cholesterol transport. The objective of this work was to examine the effect of three distinct conformations of apoA-I (lipid-free and ...

Charge-induced phase separation in lipid membranes [PDF]

, 2014
The phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of ...

Automated analysis of giant unilamellar vesicles using circular Hough transformation [PDF]

Bioinformatics, 2014
Abstract Motivation: In order to obtain statistically relevant results, the study of membrane effects at the single-vesicle level requires the analysis of several hundreds of giant unilamellar vesicles (GUVs), which becomes a very time-consuming task if carried out manually.

Method for immobilization of living and synthetic cells for high-resolution imaging and single-particle tracking

Scientific Reports, 2018
Super-resolution imaging and single-particle tracking require cells to be immobile as any movement reduces the resolution of the measurements. Here, we present a method based on APTES-glutaraldehyde coating of glass surfaces to immobilize cells without ...

Low-cost equipment for electroformation of Giant Unilamellar Vesicles

HardwareX, 2018
Giant Unilamellar Vesicles (GUVs) constitute a very useful model for biomembranes. They are usually generated by electroformation using sinusoidal potential waves applied between two platinum electrodes or electrodes composed of glasses covered by indium

Emergent Motility of Self‐Organized Particle‐Giant Unilamellar Vesicle Assembly

Advanced Materials, EarlyView.
Giant unilamellar vesicles (GUVs), when combined with silica particles under alternating electric fields, spontaneously self‐assemble into motile structures. Asymmetric particle decoration induces fluid flows that propel the assemblies, enabling persistent motion and reversible control.

Reconstitution of proteins on electroformed giant unilamellar vesicles [PDF]

, 2015
In vitro reconstitution of simplified biological systems from molecular parts has proven to be a powerful method for investigating the biochemical and biophysical principles underlying cellular processes. In recent years, there has been a growing interest in reconstitution of protein-membrane interactions to understand the critical role played by ...
