Texto completo da fonteInhibitory macrophages (iMacs), recruited during intense immune responses, exert immunosuppressive functions via a NO secretion and cellular interactions with activated T lymphocytes. These cells could limit expansion of autoreactive T cells and may thus participate to the control of autoimmune disease development. The aim of our study was to characterize iMacs phenotype and function in a privileged model of autoimmune diabetes, the non obese diabetic (NOD) mouse comparatively to the BALB/c mouse. As the origin of iMacs was poorly known, we showed firstly their differentiation from hematopoietic progenitor cells. Secondly, we described that iMacs could not differentiate and mature in vitro efficiently from hematopoietic progenitors of NOD mouse. Finally, following an immunosuppressive treatment with cyclophosphamide, known to induce iMacs recruitment in spleen of BALB/c mice, we observed deficiencies of NOD mouse iMacs differentiation and function

Texto completo da fonteDiabetes is a constantly progressing pathology described by a high blood-glucose levels. Its treatment is currently based on insulin therapy to regulate glycaemia levels, and several drugs standards for cardiovascular diseases. However, a better understanding of mecanisms involved in its physiopathology remain needed to improve patients care. Thus, we studied here the role of angiotensin Il type 2 receptor (AT2R) in development and cardiovascular complications of diabetes mellitus. Indeed renin-angiontensin system is a key regulator of diabetes physiopathology but is targeted mostly by angiotensin Il type 1 receptor antagonists and angiotensin converting enzyme inhibitors. By using two models of diabetes mellitus (type 1 and type 2) and a AT2R knock-out mouse model that AT2R interestingly possesses two opposite roles in diabetic pathology : it protects from diabetes induction and development but improve vascular complications associated with diabetes as endothelial dysfunction and vascular remodeling. Our results show that AT2R could be a new therapeutic target in diabetes

Texto completo da fonteTo day, it is difficult to distinguish the respective role of obesity and metabolic disorders as insulin resistance and/or type 2 diabetes mellitus in the occurrence of respiratory disorders and notably sleep apneas since these disorders are typically diagnosed late in their course. Data from literature suggest that, although increase morbidity and mortality from this syndrome, the mechanisms underlying this pathology remain poorly understood. This lack of knowledge stems in part from a paucity of animal models to study naturally occurring apnea during sleep. The aim of this work was to study insulin resistance and type 2 diabetes mellitus repercussions on energetic metabolism, ventilation, apneas occurrence in absence of obesity and diaphragmatic contractility by using the rat model fed high fat diet developed by Reed et al (metabolism, 2000). Our study was also designed to assess whether the use of metformin, one of the most common drugs used in the treatment of insulin resistance, could reverse or suppress the possible ventilation impairments and apnea occurrence. This study demonstrates that insulin resistance increases apneas score during sleep in absence of obesity. This increase was reversed by metformin treatment reinforcing the idea that insulin resistance could induce ventilatory disorders during sleep independently of obesity. This study also demonstrated that metformin treatment in parallel with high fat fed diet prevent the development of sleep apnea syndrome. The decrease, in vitro, of the force of diaphragm, the principal inspiratory muscle, could be linked to an increase of apnea during sleep. Indeed, morphological modifications in diaphragmatic fibres had been shown with an increase of type IIb fibres and a decrease of type I and IIa fibres in diabetic rats

Texto completo da fonteExcessive glucocorticoid (GC) exposure, as seen in patients receiving GC therapy, can lead to β-cell dysfunction and diabetes in up to 40% of the cases. In obesity, increased local cortisol exposure due to altered metabolism contributes to diabetes onset. High doses of GCs like dexamethasone (DEX) are known to inhibit glucose-stimulated insulin secretion (GSIS), but the effects of lower doses and other GCs, such as hydrocortisone (HC) and prednisone (PRED), remain underexplored. The enzyme 5α-reductase type 1 (SRD5A1) is a crucial enzyme for GC degradation, modulating their bioavailability. Inhibition or knockout of SRD5A1 is associated with impaired insulin sensitivity and increased diabetes risk. This first part of my thesis investigates the impact of “low therapeutic” doses of PRED (equivalent to 5 to 10 mg administrated orally) and other GCs on glucose stimulated insulin secretion (GSIS). We showed that PRED significantly decreases GSIS, with DEX having a worse effect compared to PRED and HC. BMI, age, or sex do not significantly influence the direct impact of PRED on insulin secretion. The second part of the work aimed to characterize GC metabolism in human islets. SRD5A1 is the only A-ring reductase expressed in islets, and its expression, along with HSD11B1, is localized within the β-cells of human islets. We demonstrated evidence of intracrine metabolism of cortisol in intact primary human islets cultured under dynamic experimental settings. Expression data reveals significantly diminished expression of both HSD11B1 and SRD5A1 in T2D donors compared to normoglycemic donors. The last part aimed to provide proof of concept that decreased cortisol bioavailability via the overexpression of SRD5A1 in human islets mitigates the inhibitory effect of GCs on GSIS. SR5DA1 overexpression attenuated the impact of HC on the first phase of insulin secretion, but not the PRED impact. To conclude, even at low doses, GCs impair GSIS. The decrease in SRD5A1 expression in islets may contribute to the development of diabetes in metabolic context. SRD5A1 overexpression protects against the deleterious impact of cortisol on GSIS, providing additional evidence to support the enzyme's role in local cortisol overexposure and the development of diabetes. However, increasing SRD5A1 activity may not be an effective approach to protect against metabolic complications induced by GC therapy. Other aspects of β-cell function, especially cell viability, need to be studied. Moreover, the potential benefits of SRD5A1 in modulating insulin resistance and fatty liver disease should be investigated. These further studies will provide more insight into the potential of SRD5A1 as a therapeutic target

Texto completo da fonteTo have a biological function, a protein folds into a specific structure. The cell controls the correct folding of the proteins and has mechanisms to detect and eliminate misfolded proteins; nevertheless some proteins achieve to avoid this control process. Amyloid proteins are misfolded proteins that form a characteristic type of elongated amyloid fibril; depending on the protein sequence and the site of amyloid deposition they are related to different human diseases. Islet amyloid polypeptide (IAPP) a 37 amino acid peptide co-produced and co-secreted with insulin by β-cells, is involve in type 2 diabetes disease and belongs to this group of amyloid proteins. The fibrils are formed in the pancreatic islet. However the conditions under which the fibers are formed and their cytotoxicity in other cells are still unknown. Here we show that the human IAPP flanking peptides, produced during hIAPP maturation, N-terminal and C-terminal are not amyloidogenic and the toxicity of human IAPP in different cell lines. We find through biophysical assays ThT, TEM and CD that N-terminal and C-terminal residues of IAPP do not form fibrils in solution, in artificial vesicles or in cells and do not modify hIAPP toxic effect. For the toxicity of hIAPP we use Ins-1 (β-cells), SHSY5 (neuronal), F442A and 3T3L1 (adipose), mhAT3F (hepatic) and C2C12 (muscle) lines. We observe fibril formation in all cell lines, however the toxicity do not related directly with the presence of fibril. We anticipate our assay to be a starting point for more in vitro studies in different cells lines. Furthermore, IAPP fibril inhibition could be a target for anti-amyloid drug development

Texto completo da fonteNon-alcoholic fatty liver disease (NAFLD) is a chronic liver disease which is a combination of simple, slowly progressing steatosis, and non-alcoholic steatohepatitis (NASH), an inflammatory form which accelerates its progression. It is estimated that one in four people in the world is affected by NAFLD, and its prevalence is increasing rapidly, in parallel with the prevalence of its main risk factors: overweight, obesity and type 2 diabetes.This pathology is asymptomatic up to the complications, cirrhosis and liver cancer (hepatocellular carcinoma, HCC), which leads to late diagnosis and a negative impact on the associated morbidity and mortality. Furthermore, the reference diagnosis requires a liver biopsy, an invasive examination that cannot be performed routinely. As a result, the progression of the disease is poorly known and its estimation may suffer from a selection bias, towards patients with significant risk factors, who require a biopsy in the first place. A better understanding would allow the implementation of strategies to reduce its burden.The modelling approach is appropriate to take into account all susceptible patients, without having to carry out a large-scale follow-up study using liver biopsies in patients who are mostly asymptomatic. The objectives of this thesis are to describe and quantify the progression of NAFLD, to predict the associated morbidity and mortality, and to identify the population at risk, using Markov models. To do this, it is necessary to fill in some of the progression parameters via a literature review, to characterise the initial states (population likely to develop NAFLD) and the final states (mortality due to NAFLD), in order to deduce the missing progression parameters between the onset of the disease and mortality, by back-calculation.To exhaustively characterise NAFLD mortality, we identified all patients with cirrhosis or HCC from national hospital databases, representing more than 380,000 patients. We then developed an identification algorithm to determine the etiology underlying the hepatic complication, based on all the stays of the identified patients. This algorithm requires the identification of patients with cirrhosis or HCC of alcoholic or viral origin, to obtain by elimination only NAFLD patients. Once the specific mortality data had been obtained, we estimated the population likely to develop NAFLD, defined as all individuals with overweight or type 2 diabetes, excluding the population of excessive drinkers. We estimated the prevalence and incidence of this population, and modelled its evolution with age and years, based on individual data from surveys representative of the French population.Finally, we quantified the progression of NAFLD, and the impact of risk factors, using two approaches: from the literature, and from biopsy data from more than 1,800 obese patients who were candidates for bariatric surgery, resulting in a tool for predicting the progression of NAFLD in this population. We chose to back-calculate the progression parameters corresponding to the asymptomatic states, which are the most susceptible to selection bias.We obtained a model of the progression of NAFLD, taking into account the dynamic distribution of the population among weight classes and diabetes status, and resulting in the observed statistics of NAFLD deaths. The model takes into account gender, age, year, BMI (body mass index) class, diabetes status and the presence of a genetic polymorphism (PNPLA3 rs738409, C→G) as covariates of progression. It is a tool for assessing the impact of a possible treatment or public health policy on morbidity and mortality

Texto completo da fonteMitochondrial functions in the aetiology of muscle insulin resistance : clinical and animal studies. Altered mitochondrial oxidative capacities may be involved in the aetiology of muscle insulin resistance, thus promoting onset and development of type 2 diabetes. This work aimed at determining how obesity, high fat diet and oxidative stress respectively influence skeletal muscle insulin sensitivity and mitochondrial function. In a human study, we found that mild obesity is characterized by normal insulin sensitivity and a raise in mitochondrial respiration, whereas severe obesity is linked to insulin resistance and decreased mitochondrial respiration and ATP production. In Wistar rats fed a high fat diet for 14 days, insulin sensitivity was not altered while mitochondrial function was stimulated. Extending high fat diet to 40 days is accompanied by a decline in insulin sensitivity concomitantly with decreased mitochondrial respiration. In twelve-month-old SAM mice, exhibiting spontaneous chronic oxidative stress, mitochondrial respiration and muscle insulin sensitivity are stimulated compared to control mice. In the three models described, mitochondrial function modifications occur without any change in muscle mitochondrial content. In conclusion, this work evidenced that mitochondrial function adapts intrinsically to environmental conditions associated with the pathogenesis of type 2 diabetes. Following energy excess, mitochondrial function is first stimulated which may allow protecting from insulin resistance, potentially through a mild and beneficial oxidative stress. Thereafter, when obesity increases or high fat diet is extended, other regulatory pathways take place and lead to simultaneous alterations in insulin sensitivity and mitochondrial function
