Asymmetric metabolism of phosphatidylethanolamine in the human red cell membrane.

The incorporation of labeled fatty acids into phosphatidylethanolamine (PE) on the two sides of the human red cell membrane was studied by use of the vectorial probe trinitrobenzene sulfonate (TNBS). A small population of PE molecules on the outer surface of the membrane has a 4-fold higher turnover rate than the remaining PE molecules. This effect is greatest with palmitic acid, less with lino...

Red blood cell membrane phosphatidylethanolamine fatty acid content in various forms of retinitis pigmentosa.

In order to test the hypothesis that retinitis pigmentosa (RP) is associated with fatty acid abnormalities within cell membrane phospholipids, red blood cell membrane (RBC) phosphatidylethanolamine (PE) fatty acid content (% of total fatty acids) was measured using high performance liquid chromatography and capillary column gas chromatography in 155 patients from separate families with differen...

PHARMA COKINETICS OF RECOMBINANT ERYTHROPOIETIN AND RED CELL METABOLISM IN HAEMODIALYSIS PATIENTS

The pharmacokinetics of recombinant human erythropoietin (rHuEpo) administered intravenously has been investigated in a group of five patients with chronic renal failure who were dialysis-dependent. The half-life of circulating erythropoietin decreased from 7.9±OA hr (mean ±SO) at the beginning of treatment to 6.2±O.6 hr after 6 weeks and 5A±O.9 hr after 4 months of treatment. In spite of t...

Metabolic remodeling of the human red blood cell membrane.

The remarkable deformability of the human red blood cell (RBC) results from the coupled dynamic response of the phospholipid bilayer and the spectrin molecular network. Here we present quantitative connections between spectrin morphology and membrane fluctuations of human RBCs by using dynamic full-field laser interferometry techniques. We present conclusive evidence that the presence of adenos...

Patterns of Nonelectrolyte Permeability in Human Red Blood Cell Membrane

The permeability of human red cell membrane to 90 different molecules has been measured. These solutes cover a wide spectrum of nonelectrolytes with varying chemical structure, chain length, lipid solubility, chemical reactive group, ability to form hydrogen bonds, and other properties. In general, the present study suggests that the permeability of red cell membrane to a large solute is determ...
