Emerging roles for anionic non-bilayer phospholipids in fortifying the outer membrane permeability barrier.
Lately, researchers have been actively investigating Escherichia coli lptD mutants, which exhibit reduced transport of lipopolysaccharide to the cell surface. In this issue of the Journal of Bacteriology, Sutterlin et al. (H. A. Sutterlin, S. Zhang, and T. J. Silhavy, J. Bacteriol. 196:3214-3220, 2014) now reveal an important functional role for phosphatidic acid in fortifying the outer membran...
متن کاملOn Membrane Phospholipids and Protein-lipid Association
Membranes of blood cells have an asymmetric bilayer distribution of phospholipid classes. In both erythrocytes and platelet plasma membranes the choline containing phospholipids (sphingomyelin and phosphatidylcholine) are preferentially located in the outer half of the membrane, whereas a large fraction of phosphatidylethanolamine and nearly all phosphatidylserine are confined to the cytoplasmi...
متن کاملErythrocyte Membrane Cation Permeability
A B S T R A C T Cetiedil has been reported to relieve painful crises in sickle cell anemia and to have antisickling properties in vitro. The drug alters neither oxygen affinity nor the solubility of deoxyhemoglobin S. Because the viscosity of the erythrocyte interior and the kinetics ofgelation are dependent on the concentration of hemoglobin, we postulated that cetiedil might inhibit sickling ...
متن کاملPermeability Modulating Membrane Coats
Many protozoans and some other organisms possess contractile vacuoles (CVs), membranous organelles which help maintain cellular water/ electrolyte balance by extracting a dilute solution from the cytoplasmic colloid and expelling it from the cell (35, 37). Although the similarity of CV function in the various organisms has long been recognized, the expected similarity of morphological elements ...
متن کاملExtracellular processing of phospholipids is required for permeability barrier homeostasis.
Three key lipid types, cholesterol, ceramides (CER), and free fatty acids (FA), form the stratum corneum (SC) lamellar bilayers that mediate barrier function. Prior studies have shown that barrier requirements regulate CER generation from glucosylCER, and that this catabolic step takes place within the SC interstices. Here, we addressed whether extracellular processing of phospholipids (PL), th...
