Les liposomes : description, fabrication et applications [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2004
Liposomes: description, preparation and applications. Liposomes are spherical vesicles with a diameter ranging from 20 nm to a few thousands nm. These vesicles consist of one or several bilayers which separate an intravesicular from an external medium.

Effects of Lipid Composition and Solution Conditions on the Mechanical Properties of Membrane Vesicles

open access: yesMembranes, 2015
The mechanical properties of cell-sized giant unilamellar liposomes were studied by manipulating polystyrene beads encapsulated within the liposomes using double-beam laser tweezers.

Formation of Giant Unilamellar Proteo-Liposomes by Osmotic Shock [PDF]

open access: yesLangmuir, 2015
Giant unilamellar vesicles (GUVs), composed of a phospholipid bilayer, are often used as a model system for cell membranes. However, the study of proteo-membrane interactions in this system is limited as the incorporation of integral and lipid-anchored proteins into GUVs remains challenging.

Naja naja oxiana Cobra Venom Cytotoxins CTI and CTII Disrupt Mitochondrial Membrane Integrity: Implications for Basic Three-Fingered Cytotoxins. [PDF]

open access: yesPLoS ONE, 2015
Cobra venom cytotoxins are basic three-fingered, amphipathic, non-enzymatic proteins that constitute a major fraction of cobra venom. While cytotoxins cause mitochondrial dysfunction in different cell types, the mechanisms by which cytotoxins bind to ...

Analysis of the shape fluctuations of reconstituted membranes using GUVs made from lipid extracts of invertebrates

open access: yesBiology Open, 2013
Summary Changes in the physical properties of the lipid matrix of cell membranes have repeatedly been proposed to underlie stresses associated with e.g. drought, cold and xenobiotics.

A Liposomal Formulation to Exploit the Bioactive Potential of an Extract from Graciano Grape Pomace

open access: yesAntioxidants, 2022
Antioxidant compounds with health benefits can be found in food processing residues, such as grape pomace. In this study, antioxidants were identified and quantified in an extract obtained from Graciano red grape pomace via a green process.

Dibucaine in Ionic-Gradient Liposomes: Biophysical, Toxicological, and Activity Characterization [PDF]

open access: yes, 2018
Administration of local anesthetics is one of the most effective pain control techniques for postoperative analgesia. However, anesthetic agents easily diffuse into the injection site, limiting the time of anesthesia. One approach to prolong analgesia is

Diffusion of hydrogen peroxide across DPPC large unilamellar liposomes

open access: yesChemistry and Physics of Lipids, 2012
The decomposition of hydrogen peroxide catalyzed by catalase entrapped in the pool of dipalmitoylphosphatidyl choline unilamellar liposomes has been studied. The rate of the process was evaluated by following the production of oxygen as a function of time.

Preparation of unilamellar liposomes v1

open access: yes, 2023
We present here a protocol for preparing liposomes that can be used to monitor binding of proteins to vesicles of various membrane curvatures. We used this to study the association of the PPM1H phosphatase with highly curved membranes due to its N-terminal amphipathic helix.
