Full textOxidative stress appears to be involved in the development of peripheral insulin resistance leading to type 2 diabetes. Biological membranes, because of their high polyunsaturated fatty acids, are prime targets for oxidant species. Peroxidation of biological membranes is responsible for the production of many reactive species including aldehydes 4- hydroxy-2-hexenal (HHE) and 4-hydroxy-2-nonenal (HNE), respectively derived from the peroxidation of omega-3 and omega-6 polyunsaturated fatty acids. This study demonstrates that plasma concentration of HHE is increased in humans and rats during diabetes, and that intravenous injection of HHE lead to the development of insulin resistance in rats. In muscle cells (L6C5) and adipocytes (3T3-Ll), HHE and HNE cause massive carbonylation of cellular proteins and induce insulin resistance by disrupting glucose transport and the signaling pathways of insulin. These disorders can be reversed by an increase of reduced glutathione or by antioxidant treatment. HHE and HNE can also form covalent adducts on insulin, thereby reducing its hypoglycemic effect in vivo and stimulation of glucose transport in vitro. HHE and HNE are involved in the development of insulin resistance by disrupting both the intracellular signaling pathways and biological function of insulin. They are therefore potential drug targets for the prevention of type 2 diabetes

Full textThe first goal of this thesis (Study 1 and 2) was to improve the use and the comprehension of tools for red blood cell (RBC) deformability measurements in sickle cell disease (SCD). The first study showed the importance of standardization of RBC deformability measurements by ektacytometry in SCD children. In the study 2, the RBC proprieties was modified and the variation of « classic » RBC deformability curve (elongation index as a function of the shear stress in isotonic medium) was compared to osmoscan results (elongation index in hyperosmolar gradient and constant shear stress), the gold standard for RBC membrane defect studies. Thus, the modifications of RBC deformability curve above 3 Pa were affected by RBC internal viscosity and cellular surface modification (and thus surface/volume ratio) while membran elasticity modifications affected RBC deformability whatever the shear stress (low, moderate or high). The second goal of this thesis was to study the effects of genetic modifiers, hemorheological parameters and oxidative stress level on vaso-occlusive complications (VOC) in SCD (Study 3 to 6). Hemorheological parameters were measured on 165 patients from Lyon and 240 patients from Gwada and the results showed that blood viscosity increased until the age of 30 and RBC deformability decreased with age (Study 3). This modifications probably play role in the chronic complications of SCD adult patients. The studies 4 and 5 were conducted on SCD children. We studied the effects of genetic modifiers (alpha-thalassemia, glucose-6-phospho-deshydrogenase deficiency and S haplotypes ; study 3) and nitro-oxidative stress level (study 5). Alpha-thalassemia increase RBC deformability and RBC aggregation. This phenomenon could contribute to increase VOC. Moreover, alpha-thalassemia decreased hemolysis and thus oxidative stress, a major component of SCD physiopathology. Then the study 6 showed that Sbeta+ patient hemorheology was quite the same of AA ubjects but the more severe patients could have a defect in circulating nitric oxide. To conclude, my thesis contribute to a better understanding of SCD physiopathology

Full textIn order to clarify the physiopathological and inflammatory mechanism underlying familial Mediterranean fever (FMF), we evaluated the ex vivo PBMC cytokine profile of FMF patients and compared it with that of controls. Then, we tried to study the implication of RAC1 protein in oxidative stress generation and IL-1β production in FMF patients. Finally, we aimed at investigating the possible association between IL- 1β and IL- 1ra genes and susceptibility and/ or severity of the disease.The first part of the study included 34 genetically confirmed FMF patients, of whom 9 were studied during attack and remission, and 24 healthy controls. Inflammatory markers CRP and MBL were measured in serum by ELISA and cytokine levels were evaluated by Luminex technology in serum and supernatants of PBMC cultures with and without 24h stimulation of monocytes by LPS and T lymphocytes by anti-CD3/CD28 beads.In the second part of this work, we compared expression levels of RAC1 gene between FMF patients, during or between crises, and controls by quantitative real-time PCR. Then, we measured spontaneous and LPS-induced production of IL-1β and IL-6 by ELISA in supernatants of PBMC cultured in the presence or absence of RAC1 inhibitor. Evaluation of oxidative stress markers was performed in plasma and in unstimlated and LPS-stimulated PMN culture supernatants in the presence or absence of RAC1 inhibitor
