The interactions of proteins with membrane surfaces are important to many biological processes, including signaling, recognition, and membrane trafficking, cell division and cell structure. When the Fluid Mosaic Model (FMM) ...

Melittin (ML) is a small peptide of 26 residues rich in arginine (Arg) and lysine (Lys). Several studies have been done to understand the mechanism of interaction with neutral and negatively charged lipids. However, it is ...

The lipid composition of biological membranes is key for cell viability. Nevertheless, and despite their central role in cell function, our understanding of membrane physiology continues to lag behind most other aspects ...

L-ascorbic acid alkyl esters (ASCn) are lipophilic forms of vitamin C, which act as skin permeation enhancers. We investigated the physical changes induced by incorporating ASCn into stratum corneum (SC) lipid membranes ...

The cohabitation of lipids and proteins in the plasma membrane of mammalian cells is controlled by specific biochemical and biophysical rules. Lipids may be either constitutively tightly bound to cell-surface receptors ...

Cell membranes are one of the main targets of oxidative processes mediated by reactive oxygen species (ROS). These chemical species interact with unsaturated fatty acids of membrane lipids, triggering an autocatalytic chain ...

Fatty acids (FAs) are important compounds either used for energy production through β-oxidation, for membrane lipid synthesis, or for production of lipid mediators (oxylipins) through oxidations. FAs are also cytotoxic and ...

Large procyanidins (more than three subunits) are not absorbed at the gastrointestinal tract but could exert local effects through their interactions with membranes. We previously showed that hexameric procyanidins (Hex), ...

Flavonoids are a type of phenolic compound widely present in edible plants. A great number of health benefits have been ascribed to flavonoid consumption in the human population. However, the molecular mechanisms involved ...

Updates of the mosaic fluid membrane model implicitly sustain the paradigms that bilayers are closed systems conserving a state of fluidity and behaving as a dielectric slab. All of them are a consequence of disregarding ...
