Texte intégralRhamnolipids (RLs) and fengycins (FGs), are compounds produced by bacteria displaying antifungal properties against the phytopathogenic fungi Sclerotinia sclerotiorum and Botrytis cinerea. However, the induced biocidal effects, and the involved mechanisms are poorly understood in fungi. Due to their amphiphilic properties, a membranotropic mode of action is proposed for these interesting compounds for biocontrol. The present work demonstrates that the two Sclerotiniaceae have opposite sensitivities to RLs and FGs. A microscopy study shows that RLs can induce programmed cell death (PCD) or necrotic cell death in both fungi depending on the concentration whereas FGs systematically induce PCD, probably by triggering autophagy. Lipidomic analyses (fatty acid, phospholipid and ergosterol contents) of S. sclerotiorum and B. cinerea strains differently sensitive to RLs and FGs allow to correlate the lipid contents of the fungi to their sensitivities. These data are used to study the interactions of RLs or FGs on biomimetic plasma membrane models of the two fungi. The dynamics show that the RLs monomers insert into the models without fluidizing them and that the FGs auto-aggregate themselves and insert into some models, inducing fluidization. Ergosterol and phosphatidic acids seems to disfavour this insertion while phosphatidylcholine and phosphatidylethanolamine seem to favour it.This work allows to better understand the antifungal mode of action of RLs and FGs, with a view to develop more effective biocontrol products for crop protection targeting specific pathogens

Texte intégralThe use of antibacterial agents is very important, firstly, on the fight against bacterial infections, and secondly, to keep food products until its consumption. The loss of antibiotics effectiveness through the development of bacterial resistance and the toxicity of synthetic preservatives necessitates the development of new natural antibacterial products. Antibacterial proteins and peptides acting on the bacterial membranes appear as an alternative to limit the introduction of bacterial resistances. Ovotransferrin is an egg-white protein with membranotropic properties responsible among other things for its antibacterial activity. The aim of this thesis is to study the membranotropic mechanisms of ovotransferrin towards the outer and cytoplasmic membranes of E. coli using respectively monolayers of LPS (lipopolysaccharides) and phospholipids as experimental membrane models. Ovotransferrin has an insertion capacity in LPS monolayer that is dependent on protein concentration, monolayer compactness, and LPS molecule conformation. Ovotransferrin weakly adsorbs to the monolayer of phospholipids. Thus, the monolayers are disturbed by the disorganization of the lipids. Comparative analysis of dry-heated ovotransferrin with the native form showed conservation of secondary and tertiary structures with an increase of surface hydrophobicity and probably of flexibility and higher affinity to hydrophilic/hydrophobic interfaces (water/air). The insertion capacity in the LPS monolayer is amplified with greater affinity. Insertion capacity in the phospholipid monolayer is generated for the dry heated form associated with higher adsorption. Dry-heated ovotransferrin induces greater disruption of monolayers at lower protein concentrations

Texte intégralIn order to improve the treatment of triple negative breast cancer (TNBC), the objectives of this work are: 1) to optimize the formulation of a siRNA nanovector (CS-MSN) functionalized by a cell penetrating peptide to increase its transfection efficiency and to obtain features compatible with a systemic administration, ii) to investigate its internalization mechanisms and pathways and its intracellular trafficking and iii) to validate its efficiency on a TNBC cell model. The optimization of CS-MSN formulation resulted in a nanovector with a size of about 170 nm with a slightly positive surface charge. CS-MSN showed an ability to protect siRNA against degradation in the presence of serum without remarkable cell toxicity. The entry of CS-MSN in cells is enhanced by the presence of the membranotropic peptide gH625 on their surface and involves a clathrin- and caveolae-mediated endocytosis pathway. CS-MSN showed an ability to escape degradation in endo-lysosomal vesicles, facilitated by the gH625 peptide. This endosomal escape results in 73% of inhibition of the GFP protein expression and a significant reduction of Bcl-xL mRNA and protein
