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 thiocarbohydrazide. After critical point drying, the specimens were coated with a thin (less than 2 nm) continuous film of chromium. On the cytoplasmic aspect of the dorsal plasmalemmal fragments seen in such specimens, plasmalemmal vesicles appear as uniform vesicular protrusions approximately 70-90 nm in diameter, preferentially concentrated in distinct large fields in which they occur primarily as single units. Individual plasmalemmal vesicles exhibit a striped surface fine structure which consists of ridges approximately 10 nm in diameter, separated by furrows and oriented as meridians, often ending at two poles on opposite sides of the vesicles in a plane parallel to the plasmalemma. This striped surface structure is clearly distinct from the cage structure of coated pits found, at low surface density, on the same specimens. The cytoplasmic aspect of the plasmalemma proper is covered by a fibrillar infrastructure which does not extend over plasmalemmal vesicles but on which the latter appear to be anchored by fine filaments.

Abstract:
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 plasmalemmal structure of different vertebrate classes). Measurements were made on tissues conventionally prepared for freeze fracture by glutaraldehyde fixation and cryoprotection. We found that, in the same sheep hearts, lambda and Ap for ventricular plasmalemma significantly exceeded those for atrial plasmalemma and that the distribution of atrial P-face particles was more clustered than that for ventricle. d and Ap for frog ventricular plasmalemmal P-face significantly exceeded values for some of the other vertebrates.

Abstract:
A bioatividade de ácidos húmicos (AH) isolados de lodo da estação de tratamento de esgoto (AHL) e de vermicomposto (AHV) foi avaliada pela ação dessas substâncias sobre o transporte de prótons através da membrana plasmática de células de raízes de café e milho e sua relação com o desenvolvimento dessas espécies. Houve estímulo da área superficial radicular em ambas as espécies cultivadas com ambos AH, mostrando uma concentração ótima em torno de 40 mg L-1. Nessa condição, os tratamentos com AHL e AHV estimularam a H+-ATPase de membrana plasmática em plântulas de café e milho. Os AHL foram mais efetivos na promoção desses efeitos do que os AHV. A modificação do perfil cromatográfico dos AH em solução antes e após o cultivo das plântulas revelou que a interação planta-AH promoveu uma redistribuição das massas moleculares dessas substâncias, sugerindo uma dinâmica de mobilização de subunidades funcionais dos AH por exsudatos das raízes. A análise estrutural dos AH detectou a presença de grupamentos de auxina. A análise comparativa da ação desses dois AH sobre as espécies representantes de plantas monocotiledôneas (milho) e dicotiledôneas (café) apontam para a ativação da H+-ATPase de plasmalema como possível marcador metabólico de bioatividade dos ácidos húmicos.

Abstract:
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 microdomains decreased as follows: plasmalemma proper greater than coated pits greater than stomal diaphragms of plasmalemmal vesicles and transendothelial channels, and fenestral diaphragms. The membrane of plasmalemmal vesicles and transendothelial channels was not labeled by FH. Nonspecific binding of FH to the nonoxidized endothelial surface or that oxidized after neuraminidase treatment was relatively low.

Abstract:
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 that bind restrictively to plasmalemmal vesicles, gA-Au labels the plasma-lemma proper, plasmalemmal vesicles open on the lumen, and most coated pits. Competing albumin prevents gA-Au binding to the membrane of plasmalemmal vesicles, while glucose significantly reduces the ligand binding to plasmalemma proper. Competition with albumin and glucose gives additive effects. Transcytosis of gA-Au, already detected at 3 min, becomes substantial by 30 min. No tracer exit via intercellular junctions was detected. gA-Au progressively accumulates in multivesicular bodies. The results of the binding and competition experiments indicate that the gA behaves as a bifunctional ligand which is recognized by two distinct binding sites: one, located on the plasma membrane, binds as a lectin the glucose residues of gA; whereas the other, confined to plasmalemmal vesicles, recognizes presumably specific domains of the albumin molecule.

Full text
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 parameters of the caveolae and their membrane (e.g., size-specific gravity and solubility in detergents) which do not rule out contamination from other membrane sources, especially the plasmalemma proper. We report here a different method for the isolation of PVs from plasmalemmal fragments obtained by a silica-coating procedure from the rat lung vasculature. The method includes sonication and flotation of a mixed vesicle fraction, as the first step, followed by specific immunoisolation of PVs on anticaveolin-coated magnetic microspheres, as the second step. The mixed vesicle fraction, is thereby resolved into a bound subfraction (B), which consists primarily of PVs or caveolae, and a nonbound subfraction (NB) enriched in vesicles derived from the plasmalemma proper. The results so far obtained indicate that some specific endothelial membrane proteins (e.g., thrombomodulin, functional thrombin receptor) are distributed about evenly between the B and NB subfractions, whereas others are restricted to the NB subfraction (e.g., angiotensin converting enzyme, podocalyxin). Glycoproteins distribute unevenly between the two subfractions and antigens involved in signal transduction [e.g., annexin II, protein kinase C alpha, the G alpha subunits of heterotrimeric G proteins (alpha s, alpha q, alpha i2, alpha i3), small GTP-binding proteins, endothelial nitric oxide synthase, and nonreceptor protein kinase c-src] are concentrated in the NB (plasmalemma proper-enriched) subfraction rather than in the caveolae of the B subfraction. Additional work should show whether discrepancies between our findings and those already recorded in the literature represent inadequate fractionation techniques or are accounted for by chemical differentiation of caveolae from one cell type to another.

Full text
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 regulation. Other cytoplasmic structures are correlated with the enhanced plasma membrane, indicating possible pathways of membraneogenesis. Return to the normal epidermal cytomorphology evidently entails a large-scale disassembly of plasma membranes.

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-bearing CHO cell line. In the unstimulated state, receptors were diffusely distributed over the plasmalemma. Agonist occupation stimulated endocytosis via both clathrin-dependent and independent pathways. The former was predominant, leading to endosomal and lysosomal compartments, as well as recycling to the plasmalemma. The clathrin-independent processes led to a smooth vesicular compartment adjacent to the plasmalemma resembling caveolae, which did not transport ligand deeper within the cell. Potassium depletion largely eliminated clathrin-dependent endocytosis, while not interfering with agonist-stimulated receptor movement into subplasmalemmal smooth vesicle compartments. These cellular endocytic events can be related to the established cycle of CCK receptor phosphorylation and dephosphorylation, which we have previously described (Klueppelberg, U. G., L. K. Gates, F. S. Gorelick, and L. J. Miller. 1991. J. Biol. Chem. 266:2403-2408; Lutz, M. P., D. I. Pinon, L. K. Gates, S. Shenolikar, and L. J. Miller. 1993. J. Biol. Chem. 268:12136-12142). The rapid onset and peak of receptor phosphorylation after agonist occupation correlates best with a plasmalemmal localization, while stimulated receptor phosphatase activity correlates best with receptor residence in intracellular compartments. We postulate that the smooth vesicular compartment adjacent to the plasmalemma functions for the rapid resensitization of the receptor, while the classical clathrin-mediated endocytotic pathway is key for receptor downregulation via lysosomal degradation, as well as less rapid resensitization.

Abstract:
We investigated the luminal surface of the continuous endothelium of the microvasculature of the murine heart and diaphragm to find out whether it has differentiated microdomains. The probes were ferritin molecules, cationized to pI's 6.8, 7.15, 7.6, 8.0 and 8.4, which were introduced by retrograde or anterograde perfusion through the aorta or vena cava after the blood was removed from the vasculature. The pattern of labeling was analyzed by electron microscopy and assessed quantitatively by morphometry in arterioles, capillaries, and venules identified in bipolar microvascular fields in the diaphragm. The results showed that the plasmalemma proper was heavily but discontinuously labeled by all cationized ferritins (CF) used, the labeling being less extensive on the venular endothelium. CF had access as individual molecules to a fraction of the vesicular population opened on the luminal front of the endothelium. Plasmalemmal vesicle labeling increased from approximately 10 to approximately 25% as the pI decreased from 8.4 to 6.8. Vesicle labeling also increased with CF concentration in the perfusate. All CF binding sites were removed by pronase and papain. Heparinase and heparitinase caused only a slight reduction in CF labeling. Neuraminidase decreased the extent and density of labeling, especially on the plasmalemma proper of the venular endothelium; this decrease was particularly pronounced in old animals.

Abstract:
Dans cette thèse, nous avons rapporté les caractéristiques biochimiques des ATPases associées à la membrane plasmique de cellule d’Acer pseudoplanatus. Nous avons également démontré que la membrane plasmique renferme des systèmes d’oxydo-réduction dont le fonctionnement acidifie le milieu extracellulaire. Parmi 51 carbanilates analogues d’un herbicide, le SWEP, nous avons mis en évidence 10 molécules inhibitrices des ATPases du plasmalemme de cellules végétales ou animales. Ces molécules sont sans action sur les ATPases mitochondriales et sur les phosphohydrolases solubles, et semblent donc posséder une bonne spécificité pour les ATPases tonoplastiques. D’autre part, 14 carbanilates analogues d’un autre herbicide, le phenmédiphame, se sont révélés comme des inhibiteurs des systèmes d’oxydo-réduction étudiés. Ces molécules se sont révélées toxiques pour les suspensions cellulaires utilisées, et leurs effets in vivo ont pu être expliqués par leur action biochimique déterminée in vitro. Elles n’ont pas exprimé cependant d’effets toxiques importants lorsqu’elles ont été administrées à des plantes. Nous avons ensuite apporté des arguments en faveur d’un couplage entre les systèmes d’oxydo-réduction et les ATPases associés à la membrane plasmique. Dans une telle hypothèse, les ATPases assureraient le transport des protons générés par le fonctionnement des systèmes d’oxydo-réduction. Ce couplage pourrait être indirect, par l’intermédiaire du gradient électrochimique des protons, ou direct, par l’intermédiaire d’un facteur moléculaire de couplage. En conséquence, on en arrive à la conclusion que les sites d’action des différents carbanilates étudiés pourraient être les ATPases ou/et les systèmes d’oxydo-réduction proprement dits, ou encore le ou les site(s) de couplage. Ces différentes possibilités sont discutées, et un schéma récapitulatif du mécanisme d’action des molécules étudiées est proposé
A study has been carried out to characterize the biochemical properties of plasmalemma ATPase from Acer pseudoplatanus cells, and to report evidences for the presence of a trans-plasmamembrane electron transport system, the activity of which is associated with a concomitant external medium acidification. Among 51 carbanilates derived from the herbicide SWEP, we have found 10 specific inhibitors of plasmalemma ATPases. These chemicals are inactive on the mitochondrial ATPase, and the soluble phosphatase activities (the tonoplastic enzyme was not studied). On the other hand, 14 carbanilate derivatives from another herbicide (phenmedipham) appear as inhibitors of trans-membrane redox systems. These chemicals are toxic for in vitro cell cultures, and these cytotoxic properties are consistent with their biochemical mode of action. This toxicity is not expressed at the whole plant level, however. Moreover, we report evidences for a coupling between the redox systems and the ATPases associated with plasmalemma. In this way, ATPases could perform the transport of protons provided by the activity of the redox systems. This coupling, which results in a mutual regulation of the two systems, could be governed by the electrochemical proton gradient, or by a molecular site. According to these possibilities, the target of the two groups of carbanilates could be either the ATPases or the redox systems associated with the plasmalemma, or the site of coupling. These different possibilities, which are not mutually exclusive, are discussed, and a recapitulative scheme of the mechanism of action of the inhibitors is proposed

Chez les angiospermes, les cellules associées aux vaisseaux (CAVs) sont situées à la jonction entre les voies de transport vertical de la sève xylémienne et les voies de transport radial des nutriments. Les flux de sucres entre ces deux tissus via les CAVs se font par 2 mouvements opposés : l'efflux et l'influx. L'influx se ferait par un co-transport H+/sucres dépendant du gradient de pH généré par l'ATPase-H+ du plasmalemme. Nous avons entrepris d'étudier les CAVs et notamment leurs ATPases-H=+ du plasmalemme afin de définir leurs rôles chez le noyer. En hiver, nous avons observé, une faible activité de l'ATPase-H+ du plasmalemme dans la partie apicale du rameau, contrairement à la partie basale. Au printemps, à la reprise de croissance, nous avons observé une forte activité de l'APTase et un fort marquage dans des les VACs de la partie apicale du rameau.

Abstract:
It is widely held, that the constituents packed in the a -granules are released by stimulated platelets via the surface connected system (SCS). By means of the fast-freezing and freeze substitution technique (which allow the investigation of membrane fusion) we found a secretory pathway in platelets (compound exocytosis) without an involvement of the SCS during the release of a-granules. To study the process of a-granule secretion human platelets concentrated in citrated blood plasm were stimulated with thrombin or collagen. 20 - 120 seconds after stimulation the platelets were rapidly frozen with a metal-mirror attachment to the KF 80 cryofixation unit (REICHERT-JUNG). Using plastic spacers droplets of the PRP were slammed against a copper block at 80 K at a rate of 0.2 m/sec. After cryofixation the specimens were transferred (in liquid nitrogen) into a Cs-auto cryosubstitution unit (REICHERT-JUNG). Cryosubstitution was programmed for 48h at 193 K in acetone with 4% osmium tetroxide. The temperature went automatically up to room temperature at a rate of 10 K/h. The specimens were embedded in araldite. The analysis of serial ultrathin sections of platelets in different phases of exocytosis revealed the following. a -granules in apposition showed different stages of swelling and dispersal of their electron dense matrix. Membrane appositions were also found between a -granules. The contraction of a sphere of microfilaments and microtubules during stimulation seemed to support this process. On the other hand this internal contraction prevented most of the a-granules from contacting with the plasmalemma. We observed fusion between swollen -granules in apposition and the plasmalemma and swollen and unswollen a -granules. Thus, large compound granules were formed frequently before fusion of the secretory organelles with the plasmalemma took place. These observations suggested that a -granules in stimulated platelets performed a compound exocytosis after swelling. The process seemed to start with the apposition of a -granule membranes to the plasmalemma. It cannot yet be answered whether the swelling of the granules is due to an osmotically driven influx of water or due to an influx after microfusion.Supported by DFG, Grant Mo 124/2-4
