Effects of adjuvants of the cholera toxin family on CD4 + T cell responses in a murine model of intrarectal immunization with rotavirus-like particles
2011
Mucosal immunization is an important goal of vaccine development to protect against pathogens that use mucosa as portals of entry. However, the use of non-replicating antigens requires the addition of adjuvants.Cholera-like enterotoxins, cholera toxin (CT) from Vibrio cholerae and the heat-labile enterotoxin (LT) from toxinogenic strains of E. coli, as well as the mutant LR-192G and their B subunits (CTB and LTB) have been shown to increase immune responses against unrelated co-administered antigens by mucosal routes. However, their mechanism of action is very complex and not completely understood and differences exist between holotoxins and B subunits and within molecules, differences exis…
Trophic relationships between the cultivated plant and arbuscular mycorrhizal fungi. Importance of arbuscular mycorrhizal fungi on plant production (…
2018
French : Dans son environnement, la plante interagit sans cesse avec des microorganismes. Elle est confrontée à une variété de microorganismes bénéfiques, neutres ou pathogènes, qui sont fortement dépendants des ressources carbonées que la plante libère dans le sol, leur conférant ainsi un apport de nutriments et d’énergie nécessaire à leur développement. La mycorhize à arbuscules est une symbiose mutualiste formée par 80% des plantes terrestres datant de l’Ordovicien, i.e. environ 450 millions d’années avant notre ère. L’ensemble des travaux de recherche présenté au sein de ce manuscrit, s’inscrit dans le cadre de deux objectifs généraux : (i) acquérir une meilleure compréhension des mécan…
Comparative analysis of PR gene expression in tomato inoculated with virulent Fusarium oxysporum f. sp. lycopersici and the biocontrol strain F. oxys…
2008
Non-pathogenic strains of Fusarium oxysporum have the capacity to protect plants against wilt induced by pathogenic strains of F. oxysporum. Among the mechanisms involved in this protection, induced systemic resistance has been demonstrated by using a split-root method. The aim of this study was to follow the accumulation kinetics of transcripts encoding 5 PR proteins in roots and leaves of tomato inoculated with a pathogenic or a protective strain in comparison to non-inoculated control. Moreover quantification of transcripts was assessed by real-time RT-PCR in cell cultures inoculated with the pathogenic or the protective strain. Results showed a lower expression of PR encoding genes in t…
Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)
2016
Seuls les 100 premiers auteurs dont les auteurs INRA ont été entrés dans la notice. La liste complète des auteurs et de leurs affiliations est accessible sur la publication.; International audience; In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues…

Twin Peaks: Fire Walk With Me (1992) and David Lynch's Aesthetics of Frustration
2010
This article focuses on Twin Peaks: Fire Walk With Me (David Lynch,1992), the prequel to the TV series produced by Mark Frost and David Lynch (1990-1991), which represents a turning point in Lynch's filmography. The author argues that the film's aesthetics frustrate viewer expectations, and especially the fan of the TV series, by addressing the issue of the film's relation to the TV series. Special attention is payed to the aesthetics of time passing and to the accumulation of unusual signs in the first part of the film, with reference to Deleuze and Michel Guiomar, and the way they lead the spectator, fan or neophyte, to expect something Fantastic to happen. The article then addresses the …
“A Modern Slave Song:” Reggae Music and the Memory of Slavery
2019
International audience; From early ska tunes to modern-day dancehall sounds, Jamaican popular music has been a privileged site for the re/creation and transmission of a communal memory of slavery, within Jamaican society itself but also in the broader context of the African and Afro-Caribbean diasporas. The lyrics of reggae songs constitute a vast textual repertoire where a predominantly oral discourse on slavery is produced and circulated, mostly outside institutional circles. In such texts, slavery serves as a memorial matrix which fosters a sense of identity, community and resistance for Afro-Caribbean people around the world. This chapter examines a corpus of 250 song lyrics dedicated t…
The Blues of David Lynch
2009
International audience; This article is an attempt to elaborate a typology of the color blue in the color films of David Lynch up to and including Mulholland Drive (2001). The color blue is considered alternately as light, matter or verbal language. The author studies the use, function, value and meaning of blue lighting, divided into static and flashing light, and of the blue objects in Blue Velvet (1986) and Mulholland Drive. The author shows how Lynch appropriates connotations Western culture, under the influence of Christian and romantic imagery, traditionally associates with the color blue in his cinematographic compositions. The author argues that this typology has bearing not only on…
Comment Hollywood figure l'intériorité dans les films « hollywoodiens » de David Lynch, Lost Highway (1997), Mulholland Drive (2001) et Inland Empire…
2010
en cours de publication; L'article prend comme point de départ les travaux de Zachary Baqué, traite "Lost Highway" (1997), "Mulholland Drive" (2001) et "Inland Empire" (2006) et contient un grand nombre de micro-analyses reliées entre elles. Il montre la complexité de la fonction structurante de Hollywood comme lieu, mythe et système dans les 3 films.
