Tumor necrosis factor TNF can trigger increases in membrane conductance of mammalian cells in a receptor-independent manner via its lectin-like domain. A lectin-deficient TNF mutant, lacking this activity, was able to bind to artificial liposomes in a pH-d ...
A review with 91 refs. The use of solid-state NMR as a tool to det. the structure of membrane mols. is reviewed with a particular emphasis on techniques that provide information on orientation or order. Expts. reported here have been performed in membranes ...
The technique of template synthesis by electrodeposition in the parallel pores of membranes is enhanced with the alternated deposition of different metals. Filled polycarbonate or alumite membranes constitute regular arrays of embedded wires with diameters ...
Colicins A and N are pore-forming bacterial toxins that kill Escherichia coli cells. Their mode of action involves three steps; binding to specific receptors located in the outer membrane, translocation through this membrane and the periplasm, and channel ...
The synthesis, characterization, and membrane-transport properties of a series of benzo-15-crown-5- andp-tert-butylcalix[4]arene-substituted polysiloxanes are described. Receptor-functionalized poly(dimethylsiloxane)s, randomly substituted with up to 37 mo ...
Aerolysin is one of a large group of bacterial proteins that can kill target cells by forming discrete channels in their plasma membranes. The toxin has many properties in common with the porins of the Gram-negative bacterial outer membrane, including an e ...
A Ca2+ sensor based on the admittance change of synthetic membranes supported on derivatized silicon electrodes is reported. The ion-sensitive membranes consist of mixed monolayers of phospholipid and the Ca2+-ligand ETH 1001. The electrodes are characteri ...
In the rabbit nephron, the luminal membrane surface area of the proximal convoluted tubule (PCT) is more than twice that of the proximal straight tubule (PST). What seemed to be an increase in histological specialization in solute and water transport is cu ...
Three functions have been suggested to be localized in contact sites between the inner and the outer membrane of mitochondria from mammalian cells: (i) transfer of energy from matrix to cytosol through the action of peripheral kinases; (ii) import of mitoc ...
A new method was presented to investigate the interactions between membrane receptors and their ligands in an artificial, reconstituted membrane system. Lipid bilayers were anchored via covalently attached thiolipids to TiO2/SiO2 waveguide surfaces to prod ...
