Full textFreshwater crayfish are an ancient group of decapod crustaceans. They are keystone species of freshwater habitats acting as ecosystem engineers, trophic regulators and biodiversity indicators. At the beginning of the 20th century, a collapse of native Europe freshwater crayfish populations occurred due to the introduction of the invasive oomycete pathogen, Aphanomyces astaci Schikora (1906), causative agent of the crayfish plague disease. Later, numerous introductions of invasive freshwater crayfish species, which are latently infected with their respective Ap. astaci strains, facilitated pathogen host-jumps and accelerated the decline of European freshwater crayfish stocks. However, latent infections have also been observed in European freshwater crayfish populations. In this context, my thesis focuses on elucidating the molecular mechanisms that underly the freshwater crayfish immune response to the pathogen Ap. astaci. I analyse both the susceptible and resistant host´s gene expression patterns to elucidate molecular pathways involved in the host immune response towards Ap. astaci challenge. This led me to the discovery of novel immune response factors involved in the response towards Ap. astaci, such as antimicrobial peptides (AMPs), pattern recognition receptors (PRRs), and transcription factors. My quest to elucidate the dynamics of this host-pathogen interaction has revealed that the disease progression is correlated to the pathogen progression, which occurs in multiple stages. Moreover, I identified and characterised novel transcription factors, namely CCAAT-enhancer-binding protein (C/EBP) and Krüppel homologue 1 (Kr-h1) as candidate genes in the innate immunity. Ultimately, my research highlights the complexity of the freshwater crayfish immunity, displaying how different coevolutionary mechanisms shape our understanding of this host-pathogen interaction. These results can facilitate the innovative genomic approaches in crayfish plague disease management and conservation

Full textImmune protection against viral respiratory infections requires the induction of synchronized innate and adaptive immune responses. In this thesis, the role of various immune effectors acting in the early and late phases of the immune responses after infection and vaccination was studied. A murine model of vaccinia virus nasal infection allowed us to establish the pivotal role of myeloid dendritic cells expressing the CX3CR1 chemokine receptor in the initiation of specific T cell response. These results demonstrate the existence of an early coordination between innate and adaptive arms of the immune system, which is involved in the induction of a protective response. Data from two clinical studies were used to study various immune parameters after vaccination and infection with pandemic A(H1N1)pdm09 influenza virus and to model the induced responses. A multiparametric analysis of seven effectors of the adaptive immunity shows strong heterogeneity of vaccine-induced immune responses, depending on the residual anti-influenza response. A principal component analysis identifies five profiles of adaptive responses. In addition, a year after vaccination, specific immune memory has similar characteristics to the induced responses detected after a moderate viral infection. However, the quality and intensity of memory responses after pandemic vaccine are different from the one observed after a severe infection with A(H1N1)pdm09 influenza virus. These results suggest that a balance between the different compartments of the cellular immune responses after vaccination or infection is essential for immune protection. This work opens up new ways in the correlates of vaccine efficacy and protection

Full textOur objective was to assess (i) the importance of Plasmodium vivax infections in Madagascar, (ii) the parasite sensitivity to antimalarial drugs, and (iii) molecular markers role to monitor antimalarial drug resistance. The study was led on 8 sentinel sites. An in vivo protocol was conducted according to WHO criteria. P. Vivax isolates were analysed for nucleotidic polymorphisms on pvcrt-o, pvmdr1, pvdhfr and pvdhps genes. We searched fro polymorphisms on pvcsp, pvmsp3, pvmsp1 genes and on microsatellites sequences to genotype the isolates from the in vivo protocol. Microsatellites markers were also used to assess the genetic diversity of the Malagasy isolates. Other microsatellites sequences located in the flanking regions of dhfr and dhps genes were identified to assess the origin and propagation of resistant clones

Full textL'épithélium intestinal contribue à l'homéostasie glucidique assurant la digestion des aliments, l'absorption des nutriments et la sécrétion des entero-hormones aprs un repas. GLUT2, un transporteur de sucre à haute capacité, est transitoirement recruté dans la membrane apicale des entérocytes en réponse à un repas riche en sucre. L'augmentation de l'insulinémie provoquée par l'hyperglycémie postabsorptive déclenche l'internalisation de GLUT2 dans l'entérocyte, mécanisme qui est perdu chez les rongeurs diabétiques ou rendus résistants à l'insuline par le régime. Dans le jéjunum de sujets obèses morbides résistants à l'insuline et/ou diabétiques de type 2, j'ai montré une localisation anormalement permanente, de GLUT2 dans la membrane apicale des entérocytes. La localisation apicale de GLUT2 favorise un échange bidirectionnel transépithélial de glucose. GLUT2 peut aussi s'accumuler dans les endosomes des sujets dont l'alimentation est riche en graisse et plus pauvre en hydrate de carbone. Ces localisations anormales de GLUT2 dans les entérocytes sont un signe d'adaptation pathologique de l'intestin à l'obésité humaine (Diabetes J 2011). L'obésité est une maladie inflammatoire à bas grade, affectant la sensibilité à l'insuline de plusieurs organes. L'immunité intestinale est peu étudiée dans l'obésité humaine. J'ai montré que la muqueuse intestinale des sujets obèses est hypertrophique et associée à un accroissement du nombre de cellules de l'immunité innée et adaptative. Ces modifications sont en lien avec les changements biocliniques mesurés chez les sujets obèses. Le phénotype des lymphocytes T du jéjunum a été établi en cytométrie de flux et par l'expression de gènes. L'activité des lymphocytes T de sujets obèses, pas celle des sujets minces, dégrade la sensibilité à l'insuline des entérocytes Caco2/TC7 (2 manuscripts en préparation). Nos résultats suggèrent que l'adaptation de l'immunité intestinale dans l'obésité affecte la sensibilité à l'insuline des entérocytes modifiant la fonction d'absorption des sucres dans l'intestin

Full textThe innate immune system triggers inflammatory defences against pathogens or dangerous cells but is also involved in the tolerogenic removal of apoptotic cells. Target recognition is mediated by a wide range of soluble or membrane proteins. Among them are the essential complement recognition proteins: mannose-binding lactin, C1q and ficolins. Whereas the structural recognition properties of mannose-binding lectin BL have been extensively studied, the corresponding properties of ficolins and C1q with their ligands had to be deciphered at the atomic level. This was thus the aim of the first part of the project presented here. This was experimentally studied through the X-ray structural analysis of the corresponding ficolins and C1q recognition domains, alone or in complex with several cognate ligands. We have shown that H- and M- ficolins possess only one binding site, conserved among fibrinogen-like domains. This conserved site does not seem to be active in L-ficolin, but new binding sites were discovered instead, defining a larger surface of recognition more suitable to the binding of elongated polymers. Interestingly, we also found a new binding site for phosphoserine in C1q. We also provided evidence for two unique properties of M-ficolin: the binding of Neu5Ac, a classical self-marker, and a pH-dependent conformational switch of the binding site. As recognition properties of a few recognition proteins do not explain the different behaviour of immune cells with altered-self debris, we initiated a new project to understand signalling pathways in phagocytes during apoptotic cells removal. Many data suggest that a GEF complex: ELMO/DOCK is common to many pathways activated by apoptotic cells recognition and is also a point of regulation. My work in this second project was to initiate the setup of cellular tools to study the behaviour of this complex in different model cell lines. I developed quantitative phagocytic tests and also tools for detection and surexpression of ELMO1 in different cells lines. We also observed the re-localisation of cellular ELMO1 in the phagocytic cup
