Abstract:
Capillary endothelial cells have a large population of small (65-80 nm diameter in transmission electron microscopy) vesicles of which a large fraction is associated with the plasmalemma of the luminal and abluminal side. We studied the fine structure and distribution of these plasmalemmal vesicles by high resolution scanning electron microscopy in cultured endothelial cells obtained from bovine adrenal cortical capillaries. Cell monolayers were covered with polylysine-coated silicon chips, split in high potassium buffer, fixed in aldehyde mixtures, and then treated with OsO4 and thiocarbohydr

We describe a quantitative analysis of the internal structure of cardiac plasma membranes freeze fractured in situ, including the P-face particle density (lambda), the P-face particle diameter (d), the percent of fracture face area occupied by particles (Ap), and the spatial distribution of particles (random, clustered, or ordered). This analysis has been applied to seven sheep hearts to compare the plasmalemmal internal structures in ventricular and atrial myocytes and Purkinje strands of the same hearts and also to myocytes of frog, chicken, rabbit, and rat ventricles (to compare internal pl

Sialic acid-bearing molecules on the luminal surface of the vascular endothelium in mouse and rat pancreatic capillaries were detected electron microscopically by using a procedure with ferritin hydrazide (FH), after preferential oxidation of sialyl residues with sodium periodate. The distribution of FH on the endothelial surface demonstrated the existence of microdomains with various densities of sialoglycoconjugates oxidizable by sodium periodate and accessible to the tracer. On the plasmalemma proper, FH binding sites were heterogeneously distributed. Their concentration on various microdom

The binding and transport of glycoalbumin (gA) by the endothelium of murine myocardial microvessels were studied by perfusing in situ 125I-gA or gA-gold complexes (gA-Au) and examining the specimens by radioassays and EM, respectively. After a 3-min perfusion, the uptake of radioiodinated gA is 2.2-fold higher than that of native albumin; it is partially (approximately 55%) competed by either albumin or D-glucose, and almost completely abolished by the concomitant administration of both competitors or by gA. D-mannose and D-galactose are not effective competitors. Unlike albumin-gold complexes

Abstract:
Plasmalemmal vesicles (PVs) or caveolae are plasma membrane invaginations and associated vesicles of regular size and shape found in most mammalian cell types. They are particularly numerous in the continuous endothelium of certain microvascular beds (e.g., heart, lung, and muscles) in which they have been identified as transcytotic vesicular carriers. Their chemistry and function have been extensively studied in the last years by various means, including several attempts to isolate them by cell fractionation from different cell types. The methods so far used rely on nonspecific physical param

Abstract:
Tubular infoldings of the plasmalemma, and other basal structures in the epidermis of Temnocephala novaezealandiae, are described. At times, the tubular invaginations are greatly elaborated, resulting in a considerably increased plasmalemmal area; also, complex lateral interdigitations occur at the boundaries of the differentiated syncytial epithelia. Many mitochondria are associated with the elaborated membrane. These modifications suggest an enhanced ion transport across the epidermis, and the epidermis is assumed to function in combination with the protonephridial tubules in ionic regulatio

Abstract:
Receptor molecules play a major role in the desensitization of agonist-stimulated cellular responses. For G protein-coupled receptors, rapid desensitization occurs via receptor phosphorylation, sequestration, and internalization, yet the cellular compartments in which these events occur and their interrelationships are unclear. In this work, we focus on the cholecystokinin (CCK) receptor, which has been well characterized with respect to phosphorylation. We have used novel fluorescent and electron-dense CCK receptor ligands and an antibody to probe receptor localization in a CCK receptor-beari
