Etudes des relations entre la structure et la fonction de récepteurs olfactifs d’insecte

Nous cherchons à recruter un(e) étudiant(e) très motivé(e) pour une thèse qui démarrera le 1er Janvier 2021 et sera effectuée dans l’équipe HPI de l’AFMB à Marseille et l’équipe CREA de l’iEES à Versaille. Cette thèse s’inscrit dans le cadre de la découverte de nouveaux agents de biocontrôle des insectes nuisibles. 

Contexte et objectifs

Les récepteurs olfactifs représentent des cibles privilégiées pour perturber l’odorat des insectes ravageurs et contribuer à mettre au point des méthodes de biocontrôle. Cependant, l’absence de similarité avec les protéines membranaires connues est un verrou technologique pour leur étude moléculaire : leur modélisation tridimensionnelle ne peut être fidèle; l’identification du site de liaison des odorants est impossible. Ce projet propose de lever ce verrou en exploitant les développements technologiques les plus récents de la cryo-microscopie électronique à résolution atomique pour établir la structure des récepteurs aux phéromones sexuelles d’une noctuelle invasive polyphage, Spodoptera littoralis. Ces structures, affinées par la mutagénèse dirigée, serviront de matrices pour la conception d’agonistes et/ou d’antagonistes aux phéromones sexuelles, dont les effets sur les neurones et sur le comportement de l’insecte seront testés afin d’évaluer leur potentiel d’applications.

Méthode

Le projet présent propose d’utiliser la cryo microscopie électronique pour déterminer la structure atomique de récepteurs olfactifs d’insectes. Les récepteurs olfactifs sont présents dans la membrane cellulaire sous forme d’hétéro tétramères. Les complexes membranaires seront produits en cellules de mammifère, purifiés et stabilisés pour être étudiés par cryo-ME. Les données structurales seront affinées par mutagénèse dirigée.

Précisions sur l’encadrement et le déroulement de la thèse

La thèse sera co-dirigée par Alain Roussel (AFMB, Marseille) et Emmanuelle Jacquin-Joly (iEES, Versailles). Une présence effective sur les 2 sites sera nécessaire, même si une grande partie du travail sera à faire à Marseille.

Study of the mechanisms of lipids oxidation and antioxidant in complex food matrices : Example of infant formulas enriched in polyunsaturated fatty acids

PhD Summary : Food products displaying high content in polyunsaturated fatty acids are crucial for infant nutrition but particularly susceptible to lipid oxidation. Such oxidative alteration leads to the degradation of the food product nutritionnal profile and to the potential formation of toxic compounds. In food matrices, lipids are most of the time found under dispersed form (it is also the case in powders) and their oxidative behaviour is very complex. Indeed, in such heterogeneous systems, oxidation occurs primarily at oil-water interface where pro-oxidant agents come into contact with oxidable substrate (lipid) and initiate the reaction. In this context, our previous studies on model emulsions (oil-in-water) have demonstrated the importance of using antioxidant molecules able to locate predominantly at interface to optimize their activity. Similarly, we have demonstrated the key role of other tensioactive substances (emulsifier, proteins…) which can act as traps for pro- or antioxidants in the system and modulate the kinetics of oxidation. However up to now the transport and diffusion of radicals within heterogeneous food matrices is not described. And yet, we are convinced that a better understanding of these dynamics of transfer between the various components of the food systems (micellar phase-interface-lipid susbstrate) would lead to a better stabilization of food systems enriched in polyunsaturated fatty acids. The objective of this thesis will be to elucidate the mechanisms of propagation of lipid oxidation whithin heterogeneous food products, taking unsaturated fatty acids enriched infant formulas as an example. We will first work on model emulsion systems mimicking these products to unveil the mechanims of diffusion of oxidation using confocal imaging with fluorescent probes reporter of oxidation or RAMAN imaging. Then we will study the influence of natural antioxidants or proteins, used either isolated, or associated under the form of natural assemblies (vesicles, membrane fragments…) on the modulation of oxidation kinetics and will model these kinetics. In a second part of the thesis, we will validate these results in a real set of food product: infant formula in powder form. We aim at demonstrating that formulation and potentially process modification of this food product can improve its resistance to oxidation and thus improve its nutritionnal properties during storage.

A postdoctoral researcher fellowship position (18 months) in lipidomics/sterolomics is available at ISA (ANABIO-MS team)

Post-doctoral position in Lipidomics
A postdoctoral researcher fellowship position (18 months) in lipidomics/sterolomics is available at ISA (ANABIO-MS team) in close collaboration with Ecotoxicolgy group (Irstea). The fellowship funded by the ANR will be starting in September 2019.
Project
Aquatic ecosystems are exposed to environmental stressors such as chemical micropollutants from natural environment or anthropogenic activities. These chemical contaminations may result in alterations of the internal biochemical homeostasis of the aquatic organisms. The major limitation in the mechanistic knowledge of environmental chemical toxicity effects on aquatic organisms is the absence of molecular information notably at the genome wide scale in environmentally relevant species. The “omics” technologies – such as Transcriptomics, Proteomics, Lipidomics, Metabolomics – offer a great promises to help to elucidate molecular responses to exposures in aquatic organisms during specific and vulnerable life cycle stages. Lipid metabolism is the major fundamental metabolic pathway producing energy in animals. In fresh water organisms, lipids play a pivotal role in vulnerable stages like molting, reproduction, development. Recently, it has been shown that pharmaceutical drugs like hypolipidemic drugs have been detected in sewages, affecting the reproduction and population growth of crustacean amphipods (genus Gammarus). To understand and predict the effects of toxic exposures, it is crucial to describe the lipidome and to identify the affected metabolic networks. The project aim to gain a mechanistic understanding of toxic effects of hypolidiaemia drugs (statins and fibrates) on the sentinel organism, G. fossarum.
An innovative multi-omics approach (proteomics and lipidomics) will be developed to monitor metabolic perturbation on different development stages and reproductive cycles of G. fossarum after exposure with hypolidiaemia drugs.

Scientific background and project: Microalgae requires only sun light and water to fix atmosphere CO2 into organic carbon. They therefore represent a promising platform not only for production of a range of biomaterials ranging from food, fuel to green chemistry application, but also are key to achieving a carbon neutral economy. Microalgae naturally have the capacity to produce starch and lipids; starch are precursors to bioethanol and lipids are precursors to biodiesel. But high amount of starch or lipid is made mostly under conditions when cell division and growth are compromised. Our team has recently discovered for the first time that redox communication occur between peroxisome and chloroplast, two of the three most energetic subcellular organelles, and we further shown that this redox communication plays an important role in regulation of photosynthesis, lipid and starch metabolism (Kong et al 2018 Plant Cell). In this PhD thesis, we aim to further explore the impact of altering redox state on carbon reserve formation in microalgae.

Profile desired: The candidate is expected to have already some experience working with molecular biology of Chlamydomonas. Experience in Confocal microscopy a plus. He/she will be trained in algal physiology, lipidomics and metabolism. He/she will work in close collaboration with other researchers, technicians and students of the group.
