Wu, Zhi-Qian. "Caveolin in membrane nanotubes : curvature sensing and bulge formation". Electronic Thesis or Diss., Université Paris sciences et lettres, 2024. http://www.theses.fr/2024UPSLS007.
Texto completoCaveolin is one of the major protein components of caveolae, which are small cup-shaped invaginations in the plasma membrane. It is synthesized in the endoplasmic reticulum in a signal recognition particle-dependent manner and transported to the Golgi apparatus via COPII-coated vesicles. At the trans-Golgi network (TGN), caveolin 8S complexes further oligomerize into 70S complexes with the facilitation of cholesterol. They are then sorted intotransport carriers through an unknown mechanism and transported to the plasma membrane. The conventional structural model of caveolin might suggest it is a curvature-sensing protein based on its hairpin molecular shape. However, a recently discovered structure model of the caveolin 8S complex in detergent micelles based on cryo-electron microscopy, which exhibits a flat disc geometry, raises questions about its curvature sensitivity.Furthermore, cavins, another major protein component of caveolae that cooperate with caveolins in bending the membrane to form caveolae, do not associate with caveolins at the TGN. Given that no other known candidate, apart from cavins, can cooperate with caveolin to form transport carriers at the TGN, it becomes unclear how these carriers for caveolin are formed there. Therefore, in this project, we aimed to elucidate the curvaturesensitivity and induction of caveolin. We addressed these issues by reconstituting caveolin-1 (Cav1) into the membrane of giant unilamellar vesicles (GUVs) and by performing tube-pulling experiments. The results showed that caveolin is indeed a curvature-sensing protein, with caveolin 8S complexes exhibiting approximately a 5 degree tilt from the horizontal, which endows them with curvature sensitivity. Furthermore, we showed that caveolin 8S complexes can collectively generate membrane curvature at low tension and form scaffolds on the tubes at high tension. In summary, our results showed that caveolin is a curvature-sensing and -inducing protein, suggesting the possibility of its sorting into transport carriers at the TGN based on these properties. Interestingly, we observed that above a certain membrane tension Tt that depends on Cav1 density, nanotubes pulled from Cav1-GUVs no longer exhibit a constant radius and that caveolins form bulges on the tube. To explore how Cav1 form these bulges, we first observed that on average, bulges' size decreases with an increase in membrane tension. We found that the bulge size is proportional to the total amount of caveolin in the bulge, suggesting a constant Cav1 density in the bulges. Additionally, higher density of caveolin in the membrane favors bulge formation and lowers Tt. These results suggest that when the tube radius decreases, caveolin might induce formation of bulges to relax mechanicalconstraints due to the tubular geometry, but a model and high resolution imaging are now needed to explain these observations

Texto completoExploration of the four gas giant planets, Jupiter, Saturn, Uranus, and Neptune, is important for understanding the evolution of both our solar system and the greater universe. Due to their size, flight into the gas giants involves atmospheric entry velocities between 20 and 50 km/s. This is a complex issue because the entry conditions are harsh but the related velocities are mostly beyond the capabilities of current ground testing facilities. As such, this thesis examines the possibility of experimentally simulating proposed Uranus and Saturn entries at 22.3 and 26.9 km/s in a free piston driven expansion tube, the most powerful type of impulse wind tunnel. Initially, the possibility of simulating the conditions directly by re-creating the true flight velocity was investigated. It was found to be possible to simulate the 22.3 km/s Uranus entry, but not without large uncertainties in the test condition. For this reason, it was proposed to use an established test gas substitition where the percentage of helium in the H2/He atmosphere is increased, or the helium is substituted for the heavier noble gas neon. This allows just the post-shock conditions of the entries to be simulated. Theoretically it was found that these substitutions allowed both Uranus or Saturn entry to be simulated, which was confirmed experimentally using helium. Noting the current interest in sending atmospheric entry probes to both of these planets, this study has demonstrated that the required experimental capabilities are available for performing simulated experiments using test models

Texto completoThe intestinal microbiota is essential to our health by actively participating in the maintenance of intestinal homeostasis. The objectives are to study in gnotobiotic rats, the effect of the microbiota on the balance between proliferation and differentiation processes in colonic epithelial cells and to propose hypotheses on the mechanisms involved. We have shown that the transfer of a complex microbiota into germ-free rats reproduced a pattern of primocolonization and induced structural and functional maturation of the colonic epithelium with strong modulation of goblet cells. We have also demonstrated the ability of two commensal bacteria, Bacteroides thetaiotaomicron and Faecalibacterium prausnitzii, to modulate the differentiation of goblet cells, the synthesis and glycosylation of mucins. These effects would be linked at least in part by the production of acetate and butyrate. Finally, we have observed that Streptococcus thermophilus, a dietary lactic acid bacterium, induced a partial maturation of the colonic epithelium, particularly by stimulating goblet cells. Based on the specific metabolism of S. Thermophilus in the digestive tract and in accordance with our in vitro results, we propose that lactate may be a mediator of these effects. Thus, this work highlights the importance of the microbiota and the bacterial metabolites in the modulation of the intestinal barrier. This work provides new insights to understand how the microbiota modulates the homeostasis of the colonic epithelium and conversely how the host shapes the microbiota

Texto completoThe objective of thesis is to study the movements of the tube and of the projectile which influence mutually. These correlations depend on distortions of the tube, on the speed and on the acceleration of the projectile. The distortion of the tube is due to the actions of contact of the projectile and to the pressure of gases applied to the tube behind the projectile. Acceleration of projectiles are so intense as every imperfection or movement of the tube will have an all the bigger influence on the movements of the projectile and so on his initial conditions of flight, and therefore on his final precision relating to the aimed point. Offered research work includes several stages and puts different disciplines into play: - Determination of the geometry of the tubes of weapon: methodology of measures. - Understanding of phenomena in phasis of internal ballistics: experimental trials, instrumentation of projectiles. - Identification of parametres influencing performances in shooting: statistical studies. - Modelling of the tossing of the munition: numerical simulation
