Enterococci, most commonly regarded as members of the microbial flora of the gastro intestinal tract, have emerged as human pathogens of significant concern in the last decades. Principally due to their innate and acquired resistance to antibiotics, the research for new therapeutic alternatives is needed. Surface proteins play important roles in bacterial interactions between the cell and its environment, making them ideal targets for drugs and vaccine development, mainly because of their ability to interact with the host immune system. In this study, we identified and characterized some of the immunogenic surface-related proteins present in a vancomycin-resistant Enterococcus faecium clinical isolate. The identified proteins were evaluated as potential targets for vaccine development. The protein candidates were identified either by three different surface protein extraction methods or by analysis of transcriptomic data from a mouse peritonitis model. We selected for this study eight surface related-proteins, six from the proteomic approaches (BML, DdcP, LysM, PBP5, PpiC and SCP) and two (AdcAfm and PsaAfm) from the transcriptomic analysis. We were able to demonstrate that rabbit polyclonal antibodies raised against the purified recombinant proteins induced specific opsonic antibodies that mediated killing of five enterococcal clinical strains. Furthermore, we showed that passive immunization with seven of the anti-protein sera significantly reduced the bacterial load of E. Faecium E155 in mice. Altogether, our results demonstrate the effectiveness of these protein antigens as promising vaccine candidates against enterococcal infections as well as the feasibility of these proteomic and transcriptomic approaches to identify novel protein antigens

This work is about the functionalization of surfaces for the study of membranes proteins from the respiratory chain with the help of the differential spectroscopy. In the first time, the study of the cytochrome c oxidase named ba3 from Thermus thermophilus was done. It is described, that when the pH increases, homotropic electrostatic interactions disrupt the midpoint potentials of the protein. This study has highlighted the crucial role of the heme propionates in the mechanism of the protein. Then, the protein-protein interaction between two soluble hemoproteins from the respiratory chain of the same organism was studied. A complete characterization of the two isolated proteins is carried out and the formed complex is analysed. This study shows the importance of the heme propionates, which play a crucial role in this interaction and allowed us to characterize the interaction in the molecular level. Finally, a more practical application of the surface functionalization was conducted with the study of a cathode of a biopile. This project allowed us to develop a new technique for the immobilization of proteins, using 3D gold nanoparticles. We have access, through the cyclic voltammetry, to the midpoint potentials of the proteins and we can study the electron transfer. This method was first developed on the laccase from Bacillus subtilis, and then applied to the proteins already studied. The midpoint potentials obtained from the immobilized system and those obtained in solution are compared

In mammals, fertilization consists in a sequence of biological events that ends with the adhesion and the fusion of two gamete membranes. In this thesis, we develop an experimental technique to study the early stage of the adhesion between a single mouse spermatozoon and an oocyte under physiological conditions. We adapt the Biomembrane Force Probe to the study of gamete interactions and measure the evolution of the traction force between the two cells during the separation phase following a short contact. We show the existence of two types (called "E" and "V") of microdomains at the oocyte surface, which differ in their adhesion properties. The transmembrane protein CD9 tetraspanin, which is expressed by the oocyte, is necessary for the fusion process. It controls the formation of protein complexes. Measurements of the interaction forces show that CD9-null oocytes have no "E" domains. This result shows that CD9 participates in the adhesion from the very onset. Our experiments describe the modulation of gamete adhesion by the organisation of receptors at the oocyte surface. Moreover, for short contact times, single point attachment events allow us to probe the elastic response of the oocyte, to measure its effective membrane viscosity by pulling tethers, and to estimate the adhesion energy between its membrane and its cytoskeleton. The biophysical approach we developed in this thesis is complementary to biological strategies. It appears as a promising tool for the study of adhesion at the molecular level

The Midbody Remnant (MBR) is a structure that arises once cytokinetic abscission, the last step in cell division, is completed. Then, the MBR interacts with the cell surface and can play various roles in development, polarisation or cell proliferation. I first characterized a new MBR purification method. This study revealed that BST2, a protein known to anchor enveloped viruses to the cell surface, is enriched at the MBR. I thus focused on BST2 and its role at the MBR, especially in the interaction with the recipient cell plasma membrane. I fist confirmed by microscopy the enrichment of BST2 t the MBR. Similarly to viruses, the absence of BST2 increases the detachment of MBRs from the cell surface. They are thus released in the extracellular medium, increasing their transfer to neighbouring cells. Mechanistically, in parallel with virion restriction, BST2 dimerization and GPI anchor are both required for proper localization and functions of BST2 at the MBR. Using purified MBRs, we showed that BST2 at the midbody membrane -but not at the plasma membrane of the cell- is important for MBR retention to the cell surface. Altogether, these results show that BST2 localizes at the midbody remnant to promote its retention at the cell surface of non-infected cells. I propose that, in a way analogous to enveloped virions, BST2 tethers midbody remnants and participates in promoting their proper interaction with recipient cells

In living tissues, cell behaviors depend on close connections between cells and their environment, the extracellular matrix (ECM). For in vitro cell culture experiments, a classic strategy to improve cell culture is to coat cell culture supports by an ECM protein which is able to promote cell adhesion, like fibronectin. The aim of this thesis is to analyze the surfaces-proteins-cells relationship, and especially the properties of fibronectin adsorbed onto model surfaces and their influence on cell behavior. Different model supports (glass, OTS, polystyrene) are generated and characterized. Then, adsorption kinetics using various protein concentrations are followed, and the amount and the conformational changes of adsorbed fibronectin are concomitantly determined. Finally, cell adhesion and morphology are studied in different cell seeding conditions, and for two cell types
