Liquid ordered domains of tobacco cell plasma membrane : in vivo visualization, spatial distribution and modulation upon elicitation
2012
SPE IPM; International audience; The ability of lipids in complex mixtures to form liquid-ordered, sterol-rich phases, together with the association of specific proteins with sterol-enriched biochemical fractions extracted from biological membranes, gave raise to the "lipid rafts" hypothesis. This suggests the presence within biological membranes of small-sized, ordered domains, of particular lipid and protein composition, which could serve as signal transduction platforms, particularly during plant-microorganisms interactions. However, the precise organization of living cell plasma membrane is still poorly described and the spatial distribution of segregating liquid-disordered and liquid-o…
Designing ‘trait-based null model’ approaches to investigate community assembly mechanisms
2014
SPEEAECOLDURGEAPSIéquipe CAPA; During the last decade, many studies have addressed the signature of community assembly processes by assessing the deviation of a functional diversity pattern from that expected in null communities, using a randomization algorithm. The basic principle has been to compare the functional structure of a ‘local community’ with a set of randomly generated communities from a ‘regional species pool’. Specifically, it allows assessing the extent to which species constituting a community are functionally more or less similar than expected under the assumption of a random assembly, thus revealing the influence of assembly processes such as competition or environmental a…
Interactions in the network of Usher syndrome type 1 proteins
2004
International audience; Defects in myosin VIIa, harmonin (a PDZ domain protein), cadherin 23, protocadherin 15 and sans (a putative scaffolding protein), underlie five forms of Usher syndrome type I (USH1). Mouse mutants for all these proteins exhibit disorganization of their hair bundle, which is the mechanotransduction receptive structure of the inner ear sensory cells, the cochlear and vestibular hair cells. We have previously demonstrated that harmonin interacts with cadherin 23 and myosin VIIa. Here we address the extent of interactions between the five known USH1 proteins. We establish the previously suggested sans-harmonin interaction and find that sans also binds to myosin VIIa. We …
Rbt1 Protein Domains Analysis in Candida albicans Brings Insights into Hyphal Surface Modifications and Rbt1 Potential Role during Adhesion and Biofi…
2013
Cell wall proteins are central to the virulence of Candida albicans. Hwp1, Hwp2 and Rbt1 form a family of hypha-associated cell surface proteins. Hwp1 and Hwp2 have been involved in adhesion and other virulence traits but Rbt1 is still poorly characterized. To assess the role of Rbt1 in the interaction of C. albicans with biotic and abiotic surfaces independently of its morphological state, heterologous expression and promoter swap strategies were applied. The N-terminal domain with features typical of the Flo11 superfamily was found to be essential for adhesiveness to polystyrene through an increase in cell surface hydrophobicity. A 42 amino acid-long domain localized in the central part o…
Religion et sacrifices d'animaux
2006
En Gaule, la plupart des lieux de culte recèlent des dépôts d'ossements qui constituent une de nos principales sources sur les sacrifices animaux. La restitution de ces pratiques est une entreprise dont la réussite dépend de circonstances très particulières, voire exceptionnelles, tenant à la nature des vestiges, aux modalités de leur enfouissement et de leur séjour en terre, mais aussi aux conditions de fouille. L'enquête passe par la collecte de tous les indices disponibles, l'analyse visant à préciser l'identité de l'animal, puis le traitement qu'il a subi, de sa sélection au sein du cheptel aux diverses pratiques dont il a pu faire l'objet dans le sanctuaire. On dispose pour cela d'une …

Um regulador do sufrágio eleitoral : o direito de voto dos pais e chefes de família em França e em Portugal
2021
International audience; O direito de voto reservado aos pais é um tema clássico, uma vez que a ideia era excluir “maus cidadãos”, em contacto com paixões humanas e, portanto, susceptíveis de destruir os novos regimes representativos e os alicerces do constitucionalismo moderno - quer dizer : introduzir a oclocracia. As pessoas rejeitadas são mulheres (reciclando a tese romana do imbecillitas sexus), jovens (muitas vezes imaturos) e solteiros (por introduzir a imoralidade no espaço público). Esta escolha destinava-se igualmente a confirmar o papel do pai enquanto “magistrado domestico”, ou seja, um poder conservador e educador, semelhante ao novo poder real concebido pelos Liberais. Neste se…
