Lipid content and lipid type as determinants of the epidermal permeability barrier.
During terminal differentiation, mammalian epidermal lipids undergo striking changes in both composition and distribution. Phospholipids and neutral lipids are replaced by a mixture of ceramides and neutral lipids organized in intercellular lamellar bilayers. Whether all of these lipids and/or whether specific lipid classes regulate permeability barrier function is not known. When hairless mice...

Structural Determinants of Water Permeability through the Lipid Membrane
Despite intense study over many years, the mechanisms by which water and small nonelectrolytes cross lipid bilayers remain unclear. While prior studies of permeability through membranes have focused on solute characteristics, such as size, polarity, and partition coefficient in hydrophobic solvent, we focus here on water permeability in seven single component bilayers composed of different lipi...
متن کاملPostnatal ecdysis establishes the permeability barrier in snake skin: new insights into barrier lipid structures.
A competent barrier to transepidermal water loss (TEWL) is essential for terrestrial life. In various vertebrates, epidermal water barriers composed of lipids prevent excessive TEWL, which varies inversely with habitat aridity. Little is known, however, about the mechanisms and regulation of permeability relative to natal transition from the 'aqueous' environments of gestation to the 'aerial' e...
متن کاملLipid content and apoptosis of in vitro-produced bovine embryos as determinants of susceptibility to vitrification.
UNLABELLED The objective was to evaluate supplementation of fetal calf serum (FCS) and phenazine ethosulfate (PES), a metabolic regulator that inhibits fatty acid synthesis, in culture media during in vitro production (IVP) of bovine embryos. Taking oocyte fertilization (n = 4,320) as Day 0, four concentrations of FCS (0, 2.5, 5, and 10%) and three periods of exposure to PES (without addition-C...
