Étude de la biodistribution de nanoparticules de poly(acide lactique) chez le poisson-zèbre après administration muqueuse et intraveineuse / Poly(lactic acid) nanoparticles biodistribution study in the zebrafish aftermucous and intravenous administration

Rességuier, Julien 31 January 2017 (has links)
L'utilisation des nanobiotechnologies dans le domaine de la santé est en plein essor. Les nanoparticules de poly(acide lactique) (PLA) représentent un nanosystème biocompatible capable d'accroître la spécificité et l'efficacité de traitements thérapeutiques et vaccinaux administrables par voie muqueuse et intraveineuse. Toutefois, l'optimisation de ces nanosystèmes se heurte à une caractérisation incomplète de leur biodistribution in vivo, en particulier à l'échelle cellulaire.L'objectif de ce travail de thèse est d'enrichir les connaissances sur la biodistribution des nanoparticules de PLA in vivo après administration muqueuse ou intraveineuse, dans le but d'élargir les perspectives d'optimisation et d'utilisation. Animal complexe et adapté pour les études sur organisme-entier, le modèle du poisson-zèbre (Danio rerio) a été utilisé. Pour mener à bien ce projet, une méthodologie rigoureuse d'analyse de la biodistribution des nanoparticules de PLA a été développée. Ce qui permit, après administration par balnéation, d'en révéler le fort tropisme inné envers les cellules dendritiques muqueuses. Ces données ont servi à élaborer une stratégie de ciblage, utilisant la lectine agglutinine de cacahuète, capable d'augmenter la prise en charge des nanoparticules de PLA par les branchies et la peau. Enfin, l'étude du devenir de ces nanoparticules après injection intraveineuse, a révélé de nombreuses interactions avec le système circulatoire. Ce travail a permis d'approfondir la connaissance des interactions des nanoparticules de PLA avec le vivant, soulignant le potentiel prometteur de ces nanoparticules pour la vaccination muqueuse / Medecine shows a growing interest regarding nanobiotechnologies. Among them are poly(lactic acid) (PLA) nanoparticles, which represent a biocompatible and competent nanosystem to heighten the specificity and efficacy of diverse therapeutic and vaccine treatments, following mucosal and intravenous administration. However, the further optimization of such nanosystem is poised by the lack of informations regarding their in vivo biodistribution, especially at the cellular level.The main objective of this PhD is to increment the knowledge about PLA nanoparticles biodistribution in vivo, after muquous and intravenous administration, to further expand their optimisation and use perspectives. The zebrafish model has been utilized to perform this research because of his conserved complexity as well as his suitability for whole-organism studies.To fulfill this project, a precise methodology has been developed to analyze the PLA nanoparticles biodistribution. Which allowed, after bathing administriation, to unveil their robust innate tropism toward mucous dendritic cells. From these data has been established a targeting strategy, utilizing the peanut agglutinin lectin, which has been proved to enhance nanoparticle uptakes by both gills and skin mucosae. Finally, the study of PLA nanoparticles behavior and destiny after intravenous injection, revealed numerous elaborated interactions with the circulatory system.Overall, this work has been able to strengthen our understandings of PLA nanoparticles among living organisms, furthermore highlighting their promizing potential as nanovehicles for mucosal vaccines
