Full textDuring this thesis, we aimed of identifying biomarkers and particularly changes in high-density lipoproteins (HDL) in a situation of proteolytic, oxidative and bacterial aggression. In the first study, we identified soluble markers resulting from the proteolysis of hemoglobin in carotid atherothrombosis and abdominal aortic aneurysms (AAA). A peptide with a mass of 3327 Da was characterized by proteomics predominantly in the luminal layer of the AAA thrombus, and in the hemorrhagic area of carotid plaques. This peptide is issued from the proteolysis of the alpha chain of hemoglobin by the action of leukocyte elastase. In the second study, we have shown that the neutrophil activation observed in AAA patients largely contributes to the pro-oxidant state of this pathology and that this environment plays an active role in HDL modification and dysfunction in AAA. Indeed, we have shown the loss of their protective effect on LDL oxidation and on production of reactive oxygen species by smooth muscle cells. A decrease in circulating small HDL fractions (anti-atherogenic) was also observed in AAA patients. In AAA, the chronic neutrophil activation could be linked to the entry of periodontal bacteria in the bloodstream. In the last study, we analyzed modifications of HDL in the pathological context of severe infection: the septic shock. We have shown that besides having very low circulating levels of HDL, small HDL were decreased in favor of large HDL. We also observed in vitro that this phenomenon could result from the binding of bacterial compounds to HDL particles

Full textThe high HDL-C plasma levels observed in CETP-deficient subjects have afforded a rational to the development of pharmacological CETP inhibitors to increase HDL-C and to reduce cardiovascular diseases. However, clinical evaluation of 2 CETP inhibitors (Torcetrapib and Dalcetrapib) revealed that those treatments were surprisingly not able to reduce cardiovascular diseases. Indeed, these molecules induce significant elevation of plasma HDL-C levels and improve HDL efflux capacity, improving large HDL or small HDL particle function. These observations highlight the complexity of HDL function biology, which is modulated by many factors. Thus, my PhD work focused on the modulation of HDL structure and efflux capacity by clinical, genetic and metabolic factors. Furthermore, in the current context of CETP inhibitors failure, it is important to keep in mind the potent atheroprotective functions of CETP; those may be preserved to manage cardiovascular diseases. Indeed, this concept is supported by the contradictory conclusions reached by association studies between CETP and cardiovascular risk. Hence, CETP may have pro and anti-atherogenic functions, which result in either a global benefic or deleterious effect, according to individual metabolic context. Consequently, my PhD project aims to identify the extent of CETP atherogenicity in order to propose a relevant therapeutic strategy to prevent its deleterious effects and broadlier CAD development. My PhD research work affords a better understanding of HDL efflux capacity modulation by genetic and metabolic factors, highlighting that HDL-based therapy could have different effect according to metabolic and genetic context of treated patients. Moreover, as a putative explanation of CETP inhibitor failure, I demonstrated that CETP acts as an anti-atherogenic protein, as it improves plasma efflux capacity from human macrophage and modulates the postprandial inflammatory response

Full textHDL mediate the elimination of cholesterol thanks to their internalization by hepatocytes. We identified in hepatocytes a new pathway for HDL endocytosis as following: stimulation of an ectopic cell surface F1-ATPase by the HDL apolipoprotein A-I, induces the production of ADP which in turn activates the purinergic receptor P2Y13, triggering HDL endocytosis through unknown low affinity receptor(s). In one hand, we identified a major role of the small GTPase RhoA and its effector ROCK1 downstream P2Y13. This cell signalling stimulates the HDL endocytosis by remodelling actin cytoskeleton. In other hand, the study in mice showed the crucial role of P2Y13 in HDL catabolism and in the subsequent cholesterol biliary elimination. Taking together, these results demonstrate the importance of the receptor P2Y13 in cholesterol metabolism. Thus, P2Y13 appears as a new pharmacological target to control reverse cholesterol transport and prevent hypercholesterolemia

Full textThe capacité of HDL to protect LDL against oxidative stress is well established. However, mechanisms involved in such activity remain undetermined. Our firts aim was to assess the relationship between physicochemical properties of sub-fractions of LDL and their antiatherogenic in particular antioxidative (AOX) activities. We have demonstrated that HDL3 is depleted in spingomyelin and enriched in spingosine-1-phosphate as compared to HDL2. In addition, HDL3 displayed an elevated ratio of apolipoprotein AI (apoAI) to apoAII, and increased activities of HDL-associated enzymes with AOX properties. We have also studied mechanisms involved in the AOX activity of HDL Our data suggest a two-step mechanism involving transfer of phospholipids hydroperoxides (PLOOH) from oxidized LDL to HDL ; this step is influenced by the fluidity of the PL monolayer de HDL, and the reduction of PLOOH to redox-inactive PLOH largely through the action of two methionine residues of apoAI. This study emphasizes the importance of HDL in mitigating potential atherogenecity of LDL

Full textCardiovascular complications remain the main problem in chronic kidney disease (CKD) but all the reasons of this risk are not fully understood. there is an addition of traditional risk factors and uremia-related ones. Among the latter, the generation of post-translational modifications of HDL could play a role. In this work, we highlighted an excess of carbonylation by 4-HNE onto the protein part of HDL in CKD in a rabbit model of CKD and in hemodialysis and peritoneal dialysis patients. This carbonylation by 4-HNE is responsible for ablunted anti-aggregant properties of HDL mediated by a CD36-dependant pathway. We also showed that the proteome of HDL from non diabetic hemodialysis patients is deeply modified and that there were several post-translational modifications onto the protein cargo of these HDL. The generation of carboxylate-methyl-lysine from non-enzymatic glycation processes was the main modification in our patients. The origin of such glycation could be from a favorable chemical environment but a potential load from hemodialysis fluids should be addressed
