Among its many functions, vascular endothelium modulates vascular tone by secreting vasodilators and vasoconstrictors factors. Some diseases alter this balance, causing endothelial dysfunction which reduces organ perfusion and may jeopardizing the life. The work presented shows the interest of exploring endothelial dysfunction through endothelium-dependent relaxation studies, both in vitro through the analysis of aortic vascular ring reactivity in chamber organ and in vivo through flow-dependent dilatation of the humeral artery measurement, in response to a post-ischemic hyperaemia. In a model of aged rats with type 1 diabetes induced by streptozotocin, the late introduction of an IEC is deleterious on the exercise capacity. The normalization of blood pressure induced by the IEC could affect muscle perfusion. Endothelial function was not impaired and was not affected when the term of diabetes was lower. In a genetic model of Goto-Kakizaki rat type 2 diabetes, there was endothelial dysfunction related to the production of vasoconstrictors prostanoids. It was not improved by training even if training improved glycemic profile. In stable heart transplant patients with “normal” cardiac function, the persistent rise of plasma BNP values appeared to be related to endothelial dysfunction. While among hepatic transplant patients, normality of the endothelial function could be linked to the low prevalence of cardiovascular risk factors and a possible direct protective effect of Tacrolimus

Pancreatic islet transplantation is an innovative cellular therapy for the management of diabetes in patients with type 1 diabetes. Currently, there are few studies that address the prognostic impact of islet transplantation in patients with type 1 diabetes who have received a kidney transplant or the determinants of transplantation success in this population. Furthermore, the definition of diabetes is evolving, with the dichotomy between type 1 and type 2 diabetes fading in favor of diabetes classifications based on the patient's clinical and biological phenotype. Pancreatic islet transplantation could potentially be expanded to other profiles of patients with diabetes and a kidney transplant, especially if there's evidence of insulin secretion deficiency. Thus, the objective of this thesis is to determine the role of pancreatic islet transplantation in patients with diabetes and a kidney transplant.In the first section, we present the results of a nationwide cohort study assessing the effect of pancreatic islet transplantation following kidney transplantation compared to insulin alone in patients with type 1 diabetes. Islet-after-kidney recipients were matched to control patients using a time-dependent propensity score. After matching, pancreatic islet transplantation is associated with a reduction in the combined risk of death and return to dialysis, as well as the isolated risk of death. This study emphasizes the importance of considering islet transplantation as a full-fledged therapeutic alternative, especially in regions where it is not reimbursed or available.The second section explores the determinants of islet loss of functionality, in particular the repercussions of alloimmunity. The results of a single-center study suggest that preformed DSA and early de novo DSA have little impact on islet transplantation outcomes, but late de novo DSA is temporally associated with impaired metabolic results. No cases of cross-sensitization between pancreatic islets and the underlying kidney in recipients were described, neither in the study nor in the literature.The last section focuses on evaluating the insulin profile in patients with type 2 diabetes and a kidney transplant, through the calculation of HOMA-2 scores, to extract the impact of insulin secretion. Analysis of a single-center retrospective cohort shows an association between insulin resistance evaluated by HOMA-2 and the risk of allograft loss, while insulin secretion was only associated with metabolic balance. However, given the relationship between metabolic balance and the likelihood of death and graft loss in kidney transplant patients with diabetes, pancreatic islet transplantation could be part of the therapeutic arsenal in a personalized medicine approach for these patients.In conclusion, this thesis advocates for personalized diabetes medicine in kidney transplant patients, promoting the integration of pancreatic islet transplantation as a key component in the therapeutic strategy for these individuals

Langerhans islet transplantation allows curingtype 1 diabetes by restoring an endogenous insulin secretion. Halfof patients will resume insulin withinyears. This loss of function may be explained by the lack of monitoring tools able to diagnose an ongoing graft failure. The aims of our work were toevaluate the efficiency of MRI to diagnose islet graft rejection, and to assess the feasibility of immune cellular monitoring in transplanted patients.MRI in the rat mortelMethods: Syngeneic, allogeneic and xenogeneic islets were transplanted intra-portally to diabetic rats after labeling with superparamagnetic ironoxide nanoparticles (ferucarbotran). Images were acquired on a clinical 3T MRI scanner.Results: The signal decreasing was different between the 3 types of transplantations. At day 4, the MRI signal in allogeneic group was significantlylower while glycaemia remained normal. With a cut-off value of 84% at day 4, sensitivity of 91% and specificity of 70% were obtained.Cellular immune monitoringMethods: Mixed lymphocyte cultures were performed with peripheral blood mononuclear cells from recipients and splenocytes from donors. Immunereactivity was assessed by the release of IFNy (ELISpot), cell prolifération (flow cytometry of Ki67), and cytokine quantification (Bioplex). Theresults were correlated to the islet graft function assessed by (5-score.Results: Patients with low islet function showed higher cellular reactivity against donor cells assessed by ELISpot IFNy ((p=0,007, r=-0,50) andproliferation index (p=0,006, r=-0,51). Patients with low graft function had higher levels of IFNy, IL-5 and 1L-17

Tryptophan, an essential amino acid, is either used in protein synthesis or metabolized via the serotonin or the kynurenine pathway. The kynurenine pathway is the main route of tryptophan degradation and generates several metabolites collectively called “kynurenines”. The expression of kynurenine pathway enzymes is induced by inflammatory mediators. Consequently kynurenine synthesis could be induced in individuals with obesity. In fact, obesity is characterized by a chronic low grade inflammation of the adipose tissue reflected by increased serum levels of inflammatory factors which are known to contribute to the development of obesity-induced insulino-resistance. Some metabolites of the kynurenine pathway have been proposed to be risk factors for the development of insulin resistance. Bariatric surgery is currently the most effective treatment for severe obesity and results in a significant weight loss, a decreased level of inflammatory factors and an amelioration of glucose homeostasis. The first enzyme of the kynurenine pathway, IDO1, is known to be more expressed in the adipose tissue of individuals with obesity compared to lean individuals. The kynurenine over tryptophan ratio reflects the activity of IDO1 and is also increased in individuals with obesity.Our objective was to characterize the expression of the kynurenine pathway enzymes in the adipose tissue of women with severe obesity and to evaluate serum levels of the kynurenine pathway metabolites to determine whether these factors could be associated with the appearance of diabetes. This study was performed in women with severe obesity with or without type 2 diabetes. Then we investigated the consequences of weight loss induced by bariatric surgery on levels of circulating kynurenines in order to evaluate whether these variations could explain the improvement in glucose control and type 2 diabetes remission after one year follow-up.In this study, we have shown that several kynurenine pathway enzymes were more expressed in the adipose tissue of women with obesity compared to lean controls. This increase is due to the presence of pro-inflammatory macrophages in the adipose tissue and also comes from the adipocyte response to inflammatory stimuli. In addition, we observed that the serum level of kynurenine and kynurenine over tryptophan ratio are higher in women with higher BMI and they both decrease one year after bariatric surgery. In addition, we observed that the serum level of kynurenine and kynurenine over tryptophan ratio are higher in women with higher BMI and they both decrease one year after bariatric surgery. As expected, bariatric surgery is associated with the improvement and even the remission of type 2 diabetes. We have shown that higher levels of kynurenic acid and quinolinic acid one year after the surgery are associated respectively with type 2 diabetes remission and better glucose homeostasis and that lower levels of xanthurenic acid are associated with better glucose homeostasis

Gastric bypass procedures have emerged as an effective treatment for morbid obese diabetic patientssince they provoke a rapid remission of diabetes before any weight loss has occurred. Patients also report adisinterest in high calorie food. A suggested mechanism associated a decrease in hepatic glucose production toan enhanced intestinal gluconeogenesis. Bile acids, described as inhibitors of gluconeogenesis, see theirbioavailability changed after these procedures. Indeed, they are absent in the alimentary limb while theirplasmatic concentration is increased. We therefore tested the hypothesis that plasma bile acids may inhibithepatic glucose production while their absence in the gut could induce intestinal gluconeogenesis.For this, we performed bile diversions matching the modified biliary flow occurring after gastric bypassprocedures. We showed that bile diversions lead to an increase in plasma bile acids. Bile diversions promote ablunting in hepatic glucose production whereas intestinal gluconeogenesis is increased in gut segments devoidof bile. Moreover, the modification of bile routing per se improves glucose control and dramatically decreasefood intake due to an acquired disinterest in fatty food. This data shows that bile routing modification is a keymechanistic feature in the beneficial outcomes of gastric bypass procedures

EGA (entero-gastro-anastomosis) is a gastric bypass procedure adapted to rodent. EGA in leptin deficient ob/ob mice improves glucose tolerance by increasing pancreatic insulin content and glucose stimulated insulin secretion in vivo without persistent body weight loss dietary restriction, modification of body composition / energy expenditure. We do not observe differences in islets ‘number or size after EGA. Insulin gene expression, beta-cell proliferation (Ki67 index) and insular immune infiltration are also unchanged. Transcriptomic analysis of pancreatic islets showed that bariatric surgery differentially regulated 193 genes and 27 miRs. Interestingly, the surgery normalized molecular defects (down regulation of TRPM5, GLUT2, GCK, connexin 36) and functional alteration (high sensitivity of islets to low glucose levels) observed in diabetic ob pancreatic islets. In addition, the surgery promoted the enrichment of 227 biological process, composed of genes with known or undetermined beta cell function, especially 21 genes are involved in the hormone transport and 20 genes in the hormone secretion biological process. Computational analysis predicted that 7 of 27 miRs (324-3p, 380-3p, 671-5p, 1927, 6904-5p, 6918-5p and 7682-3p) are hubs in the miRs-gene interaction network. Altogether, our data highlighted novel molecular mechanisms in the resolution of diabetes after bariatric surgery. Overall, diabetes resolution in our model appears to be totally independent of body weight

Thesis, Lille, 2019. http://www.theses.fr/2019LILUS057.
In addition to their role in the solubilization of dietary lipids, bile acids are signaling molecules regulating their own metabolism, glucose and lipid homeostasis, energy expenditure, cardiovascular function and inflammation via the activation of the Farnesoid X Receptor (FXR) and the Takeda G protein coupled Receptor 5 (TGR5). Indeed, changes in bile acid concentrations are associated with metabolic diseases and therefore they are candidates to participate in the pathophysiology of these diseases or predict their progression.In the first part of this thesis, we studied bile acid changes in the context of obesity, insulin resistance, type 2 diabetes and non-alcoholic steatohepatitis. We demonstrated that bile acids are correlated with glucose homeostasis in humans, but that they are not predictors for the progression from prediabetes to type 2 diabetes in a longitudinal cohort study.In the second part of this thesis, we studied the bile acids in the context of bariatric surgery. Our results showed that bariatric surgery reduces the hepatic recapture of certain bile acids, causing them to increase in the systemic circulation. Additionally, we showed that it is not the bile limb but the common limb the one responsible for metabolic changes after bariatric surgery in the minipig. Finally, we showed in humans that bile acids linked to high-density lipoproteins (HDL) increase after bariatric surgery, and that this increase is correlated with the restoration of their vasoprotective functions
