Le tropisme cellulaire des prions infectieux diffère selon l’espèce animale, celui-ci est corrélé à la souche infectieuse et à des facteurs spécifiques de l’hôte. Par exemple, certains prions infectieux sont lymphotropiques, notamment en cas de scrapie chez les moutons et de variant de la maladie de Creutzfeldt-Jakob (vMCJ) chez l’homme. Par opposition, certains prions se caractérisent par un neurotropisme comme observé chez des patients Creutzfeldt-Jakob atteints de la forme sporadique ou chez des bovins atteints d’encéphalopathies spongiformes bovines (ESB). L’hypothèse de notre travail repose sur les observations suivantes : dans le cas du variant de la maladie de Creutzfeldt-Jakob et des encéphalopathies spongiformes bovines, l’agent responsable est identique, la voie d’inoculation et les lésions neurologiques le sont également, seul le tropisme de cette souche pour les organes lymphoïdes diffère. En effet, les amygdales, la rate et l’appendice sont infectieux chez l’homme. Par contre, l’infectiosité est surtout confinée au niveau du système nerveux chez le bovin. Lors d’une inoculation expérimentale par voie orale de l’agent responsable de l’ESB chez les bovins, les plaques de Peyer iléales sont les seuls tissus lymphoïdes infectieux. Notre hypothèse de travail est que des propriétés de l’hôte interviennent dans le tropisme de l’agent infectieux. Deux axes de recherche ont été envisagés afin de vérifier cette hypothèse :  L’analyse de la distribution des fibres nerveuses au sein des tissus lymphoïdes associés aux muqueuses (MALT) des espèces bovine et humaine  L’étude de l’expression de PrPc et de ses isoformes au sein des tissus lymphoïdes et nerveux des espèces bovine et humaine. Pour atteindre au mieux nos objectifs, il nous manquait un outil essentiel permettant la caractérisation spécifique des FDC bovines. En effet, aucun marqueur spécifique de ces cellules n’était commercialisé. Nous avons donc produit, en collaboration avec le Centre d’Economie Rural de Marloie, un anticorps monoclonal spécifiquement dirigé contre les cellules folliculaires dendritiques (FDC) bovines. Cet anticorps nous a permis d’étudier la distribution des FDC au sein des organes lymphoïdes bovins. Une attention particulière a été portée aux FDC isolées à partir des plaques de Peyer jéjunales (PPJ) et iléales (PPI). L’apparente différence d’infectivité de ces tissus lymphoïdes chez des bovins atteints expérimentalement d’ESB nous a conduit à comparer les capacités fonctionnelles des FDC isolées à partir de PPJ et de PPI. Ces observations sont décrites et discutées dans le chapitre 1. Dans le chapitre 2, nous avons établi une cartographie des fibres nerveuses au sein des amygdales, des plaques de Peyer iléales et jéjunales bovines de plusieurs catégories d’âge et ensuite comparé ce pattern d’innervation à celui des amygdales humaines; ceci permettra de pister les voies potentielles de neuro-invasion. Une attention particulière a été portée à l’interface cellules folliculaires dendritiques – fibres nerveuses. En effet, les FDC matures jouent un rôle prépondérant dans la pathogenèse des maladies à prion puisqu’en leur absence, une infection périphérique n’a pas lieu. De plus, la proximité entre fibres nerveuses et FDC est un paramètre intervenant dans la neuro-invasion; nous avons dès lors aussi analysé les contacts entre les FDC et les éléments nerveux. L’expression de la PrPc est une condition sine qua non pour la formation de PrPres. Cette protéine cellulaire sert probablement de récepteur pour son homologue infectieux mais sert surtout de substrat pour l’amplification de PrPres ; toute modification au niveau de sa synthèse pourrait entraîner un changement de la cinétique d’infection et pourrait expliquer l’apparente absence d’infectivité constatée au niveau du système immunitaire chez les bovins. L’expression tissulaire et cellulaire spécifique d’isoformes de la PrPc représente un facteur de l’hôte potentiellement capable d’influencer le tropisme cellulaire de l’agent infectieux chez l’humain et le bovin. Cette expression a été étudiée dans les systèmes MALT bovins et humains. Pour affiner notre étude, nous avons analysé, par des techniques de western-blotting, le glycopattern de la PrPc ainsi que l’expression de ses formes tronquées dans les tissus lymphoïdes humains et bovins mais également dans des populations cellulaires spécifiques, les lymphocytes et les FDC. Afin de vérifier si les isoformes de PrPc sont spécifiques aux tissus lymphoïdes, nous avons effectué une étude comparative du pattern de glycosylation et du ratio des formes clivées de PrPc, exprimés au sein de différentes régions du système nerveux central bovin et humain. Les résultats de ces travaux sont repris dans le chapitre 3. [less ▲]

Complex transition metal oxides span a wide range of crystalline structures and play host to an incredible variety of physical phenomena. High dielectric permittivities, piezo-, pyro-, and ferroelectricity are just a few of the functionalities offered by this class of materials, while the potential for applications of the more exotic properties like high temperature superconductivity and colossal magnetoresistance is still waiting to be fully exploited. With recent advances in deposition techniques, the structural quality of oxide heterostructures now rivals that of the best conventional semiconductors, taking oxide electronics to a new level. Such heterostructures have enabled the fabrication of artificial multifunctional materials. At the same time they have exposed a wealth of phenomena at the boundaries where compounds with different structural instabilities and electronic properties meet, giving unprecedented access to new physics emerging at oxide interfaces. Here we highlight some of these exciting new interface phenomena. [less ▲]

This article is the synthesis of the ICC research project, aiming at the development of a multimodal and portable interface supporting in real time scale setting of an architectural measurement sketch. Based on a participative process, we first expose and make a model of the traditional activities of measure taking and scale setting. We then describe the ICC software and show how the retooled activity changes, taking into account the help functions it brings. We describe the new structure of measurement activity with scale setting, the new drawing modes it induces. We conclude proposing some tracks for the software improvement. [less ▲]

In this study, we examined where immune cells and nerve fibres are located in mouse Peyer's patches, with a view to identifying potential sites for neuroinvasion by prions. Special attention was paid to dendritic cells, viewed as candidate transporters of infectious prion. Double immunofluorescence labellings with anti-CD11c antibody and marker for other immune cells (B cells, T cells, follicular dendritic cells) were carried out and analysed by confocal microscopy on Peyer's patch cryosections. To reveal the extensive ganglionated networks of the myenteric and submucosal plexi and the sparse meshworks of nerve strands, we used antibodies directed against different neurofilament subunits or against glial fibrillary acidic protein. In the suprafollicular dome, dendritic cells connect, via their cytoplasmic extensions, enterocytes with M cells of the follicle-associated epithelium. They are also close to B and T cells. Nerve fibres are detected in the suprafollicular dome, notably in contact with dendritic cells. Similar connections between dendritic cells, T cells, and nerve fibres are seen in the interfollicular region. Germinal centres are not innervated; inside them dendritic cells establish contacts with follicular dendritic cells and with B cells. After immunolabelling of normal prion protein, dendritic cells of the suprafollicular dome are intensely positive labelled. (c) 2005 Wiley-Liss, Inc. [less ▲]

Detecting signs of consciousness in patients with severe brain injury constitutes a real challenge for clinicians. The current gold standard in clinical diagnosis is the behavioral scale relying on motor abilities, which are often impaired or nonexistent in these patients. In this context, brain-computer interfaces (BCIs) could offer a potential complementary tool to detect signs of consciousness whilst bypassing the usual motor pathway. In addition to complementing behavioral assessments and potentially reducing error rate, BCIs could also serve as a communication tool for paralyzed but conscious patients, e.g., suffering from Locked-In Syndrome. In this paper, we report on recent work conducted by the Coma Science Group on BCI technology, aiming to optimize diagnosis and communication in patients with disorders of consciousness and Locked-In syndrome.

Surface properties of a nonhydrophobic fraction of proteose-peptone (NHFPP) and a hydrophobic fraction of proteose-peptone (HFPP), obtained by hydrophobic-interaction chromatography, were investigated. Adsorption of NHFPP and HFPP on the surface activity of total proteose-peptone (TPP) followed a competitive mechanism, especially during the penetration phase and molecular rearrangements. Compression of mixed monolayers was used to study the miscibility of NHFPP and HFPP within TPP films. When NHFPP was mixed with HFPP, in a TPP film, both fractions were immiscible at the beginning of adsorption; they only became miscible when the polypeptide chains had moved from the surface to the aqueous phase, thus allowing a better organisation of proteins. The equation of excess free energy of compression was used to determine the interactions of NHFPP-HFPP within the TPP film through the mixed monolayer (thermodynamic properties); interactions between NHFPP and HFPP appeared less important than those that occurred between molecules within each fraction.

Polyethylene-kaolin composites were investigated with a special emphasis on the control of the interfacial adhesion. Both matrix and filler were modified for this purpose. A stearic acid and maleic anhydride-grafted polyethylene were used as potential interfacial agents and the efficiency of aminosilane-surface-treated kaolin was considered. Tensile strength, elongation, impact strength, and melt index were currently measured in relation to the processing conditions. Enhanced interfacial filler-polymer adhesion progressively results in an decreased melt index. This has been clearly shown by comparing the effect of two polymeric additives to the polymer matrix, i.e., a maleic anhydride-grafted HDPE (MAGPE) and an unmodified HDPE of a similar melt index. Compared to low molecular weight additives, such as stearic acid and aminosilane, MAGPE has proved to be a very efficient additive in improving the impact resistance of HDPE-kaolin composites even at low contents. © 1995 John Wiley [less ▲]

Liquid crystals (LC) were covalently and ionically bonded to one (or both) end(s) of polystyrene chains. These compounds were tested as interfacial agents in polystyrene/ liquid crystal dispersions. In case of covalent bonding, the additive is too much "soluble" in polystyrene and no interfacial activity is observed. Ionic bonding of the LC to polystyrene chains deeply changes the situation, all the other conditions being the same, The dipolar interactions of the ion pairs are clearly favorable to the localization of the additive at the polymer/LC interface. The higher polarity of the ammonium sulfonate pairs com-pared to the parent ammonium carboxylate ion pairs accordingly accounts for a higher interfacial activity. [less ▲]

The fundamental surface-active properties at the oil/water interface and emulsifying properties of surfactin, iturin A and fengycin, lipopeptides from Bacillus subtilis, were investigated. All lipopeptides reduce rapidly the dynamic interfacial tension. Among lipopeptide families, surfactin is the most effective in terms of fundamental dynamic and equilibrium interfacial properties. Lipopeptides present intermediate properties in comparison with sodium dodecyl sulfate and beta-lactoglobulin concerning the stabilizing effect towards creaming-flocculation and the resistance to coalescence. Among lipopeptides, iturin A seems to show the best resistance to creaming-flocculation whereas fengycin exhibits the highest resistance to coalescence properties. (C) 1999 Elsevier Science B.V.
