Engineering Phosphatidylserine Containing Asymmetric Giant Unilamellar Vesicles
MembranesThe plasma membrane lipid distribution is asymmetric, with several anionic lipid species located in its inner leaflet. Among these, phosphatidylserine (PS) plays a crucial role in various important physiological functions.

The impact of sphingomyelin and cholesterol on ordered lipid domain formation in the bovine milk fat globule membrane using artificial giant unilamellar vesicles as a model [PDF]
JDS CommunicationsGiant unilamellar vesicle (GUV) bilayers were constructed from polar lipids and cholesterol by electroformation as a model system to investigate the formation of ordered lipid domains (OLD) within the milk fat globule membrane (MFGM).

Mechanisms of Self-Assembly of Giant Unilamellar Vesicles in the Army Liposome Formulation (ALF) Family of Vaccine Adjuvants [PDF]
PharmaceuticsBackground/Objectives: Army Liposome Formulation with QS21 (ALFQ) is a vaccine adjuvant formulation consisting of liposomes that contain saturated zwitterionic and anionic phospholipids, 55 mol% cholesterol, and small molar amounts of monophosphoryl ...

Structural and Functional Effects of the Interaction Between an Antimicrobial Peptide and Its Analogs with Model Bacterial and Erythrocyte Membranes [PDF]
BiomoleculesAntimicrobial peptides (AMPs) are a primary defense against pathogens. Here, we examined the interaction of two BP100 analogs, R2R5-BP100 (where Arg substitutes Lys 2 and 5) and R2R5-BP100-A-NH-C16 (where an Ala and a C16 hydrocarbon chain are added to ...

Instant Membrane Stabilization by Damage-Triggered Actin Polymerization in Giant Unilamellar Vesicles. [PDF]
ChembiochemDamage‐triggered actin polymerization stabilizes membrane pores in giant unilamellar vesicles (GUVs). Membrane poration drives divalent cation influx, inducing rapid F‐actin assembly at the defect site. The resulting actin plug mechanically arrests pore expansion and preserves vesicle morphology, recapitulating the “plugging” phase of single‐cell ...

Bio-Protocol, 2022 Transbilayer movement of phospholipids in biological membranes is mediated by a diverse set of lipid transporters. Among them are scramblases that facilitate rapid bi-directional movement of lipids without metabolic energy input.

Membranes, 2022 Yeast S. cerevisiae has been shown to suppress a sterol biosynthesis as a response to hyperosmotic stress. In the case of sodium stress, the failure to suppress biosynthesis leads to an increase in cytosolic sodium. The major yeast sterol, ergosterol, is
