Full textComplement system is a complex and tightly regulated innate immune defensive cascade, which can promote tissue damage, when overactivated. Hemolysis-derived danger associated molecular pattern heme is able to activate complement in serum and on endothelial cells (EC) in vitro, providing a rational for scrutinizing the impact of complement activation in hemolytic diseases. The objectives of this work were to study whether and how intravascular hemolysis induces complement activation in vivo, and to understand the underlying mechanism that leads to the acquisition of a complement activating phenotype of the endothelium in order to identify novel therapeutic strategies. We found complement deposits, including C3 activation fragments and C5b-9, within kidneys of patients with sickle cell disease (SCD) nephropathy (a prototypical hemolytic disease) as well as in a mouse model of SCD. We set up and characterized the renal injury of a mouse model of massive intravascular hemolysis, triggered by injection of phenylhydrazine (PHZ). We revealed C3 deposition within kidneys of the PHZ-treated animals. It was prevented by heme scavenging with hemopexin (Hx) and reproduced by injections of free heme, thus demonstrating the importance of heme for the complement activation in vivo. SCD erythrocytes microvesicles (MVs), are a pathologically relevant source of labile heme, since they carry three times more heme on their surface compare to MVs from healthy donors. We demonstrated that MVs, generated from SCD erythrocytes, activate complement in human serum and on EC surface, in part on a heme-dependent manner. These data highlight the importance of heme as a complement activator in hemolytic diseases. Further, we found that the C3 activation fragments deposits on endothelium in vivo and on EC in vitro can be in part explained by interaction of heme with TLR4. Indeed, the use of a specific inhibitor of TLR4, TAK-242, reduced about 50% the complement deposits on EC surface and such deposits on vascular endothelium in PHZ- or heme-injected mice were attenuated TLR4-/- mice. Moreover, we found that heme/TLR4-dependent complement deposition was mediated by the rapid expression of P-selectin, which in turn, recruited C3b and C3(H2O) on the EC surface, as evidenced by real time protein interaction analyses and using of blocking antibodies. Together our results demonstrated that heme and erythrocytes MVs are the hemolysis-derived products which promoted complement activation. At cellular level, heme induced complement-activating phenotype of EC by triggering TLR4/P-selectin axis and resulting in C3 activation fragments on cell surface. Together, these studies underline the potential benefits of Hx and TAK-242 against complement activation in pathologies related to hemolysis

Full textSoluble Flt1 is an anti-angiogenic factor, secreted by endothelial cells, monocytes and placenta, which impairs the effects of VEGF on endothelium survival and repair. It results from an alternative splicing of VEGFR1 transcript and from cleavage of the membrane-bound form of VEGFR1, and is involved in several renal diseases. Notably, it is involved in chronic diseases: it contributes to endothelial dysfunction in patients with chronic kidney disease, and is a marker of cardiovascular risks. Our team also demonstrated a correlation between sFlt1 and delayed graft function on the one side and renal vascular injuries in acute ANCA-associated vasculitis on the other side. In this context, this study aimed to assess the impact of dialysis, the long-term treatment of end-stage renal disease, on sFlt1 secretion, and on the mechanisms responsible for this secretion. We also intented to clarify the causes of renal injuries in systemic dysfunctions such as vasculitides. We enlightened a fast and large increase in sFlt1 secretion during dialysis, and we clarified the influence of dialysis methods and heparin use. Then, in vitro studies allowed us to dismiss several hypothesis of the processes at work in this increase. In conclusion, this study gives an insight into the regulatory mechanisms of the angiogenic balance involved in renal diseases

Full textWe report the spectrum of mutations in PKD1 and PKD2 genes detected by DHPLC in families with autosomal dominant polycystic kidney disease (ADPKD). In addition, we demonstrate that in PKD1 families, the risk of harbouring cerebral aneurysm and hence to exhibit a vascular phenotype is higher in families with mutation located at the 5' end of the gene. We also summarise liver complications related to ADPKD and specific treatment. In von Hippel-Lindau (VHL) disease with renal involvement, we demonstrate how conservative treatment of renal cell carcinomas may apply, and we vattempt to identify molecular risk factors for the renal phenotype. Altogether, these data demonstrate two levels of genetic heterogeneity (1) non-allelic heterogeneity

Full textIschemic acute tubular necrosis is the most common cause of acute kidney injury. The long-term risk is chronic renal failure. The development of treatments requires knowledges regarding the mechanisms of repair. Periostin is an extracellular matrix protein associated with fibrosis in models of cystic, glomerular, tubular or vascular nephropathy. In contrast to these roles, the aim of this thesis was to determine whether periostin could be an actor of renal repair in acute renal disease. In the ischemia reperfusion model, we demonstrated that periostin is produced DE NOVO by renal tubules to play an autocrine role and paracrine on the macrophage to protect the renal parenchyma. Periostin interacts with the β1 integrin on tubular cells to activate the PI3K /AKT pathway, reduce the expression of p53 and Bax and tubular apoptosis and the early loss of nephrons, and decrease p21 and cell cycle arrest, allowing early tubular proliferation. It promotes macrophage inflammatory infiltrate, via monocytes infiltration, and/or local proliferation. It causes a pro-repairing or anti-inflammatory phenotype of macrophages, depending on whether it is secreted after or before ischemia. By these autocrine and paracrine mechanisms, periostin inhibits renal fibrosis and chronic kidney failure after ischemia/reperfusion. In the model of cisplatin nephropathy, periostin limits tubular apoptosis, via similar mechanisms. Our results also suggest that periostin activates lipid catabolism in these two models of acute nephropathy. In total, periostin protects the parenchyma in acute kidney disease by several distinct mechanisms

Full textChronic kidney disease (CKD), irrespectively of the underlying cause, usually leads to nephron reduction, which is defined by a decrease in the number of the renal functional units. This is first characterized by a compensatory growth of the remaining nephrons, which in some circumstances, may result in the progressive deterioration of the initially healthy nephrons. The study of subtotal nephrectomy (Nx), a murine model of nephron reduction, has outlined the role of genetic factors in the susceptibility of developing CKD after nephron reduction. In particular, FVB/N mice (FVB) develop early and severe CKD after Nx, contrary to C57Bl/6 (B6) mice that are characterized by a preserved renal parenchyma. My work aimed at identifying new molecular pathways involved in the adaptation and progression processes in response to nephron reduction. The project was articulated around two main axes: - a "global" approach with the temporal and differential analysis of the renal transcriptome of "sensitive" (FVB) and "resistant" strains (B6) after Nx ; - a "candidate" approach centered on the study of the role of YAP/TAZ during nephron reduction. In the first work, the analysis of the renal transcriptomic expression profile of "resistant" and "sensitive" mice allowed to identify a type I interferon (IFN) signature only in the FVB mice during the renal compensation phase. This signature was correlated with a more important expression of markers of : (i) plasmacytoid dendritic cells, known for their ability to rapidly produce large amount of type I IFN; and (ii) necroptosis, an immunogenic cell death associated with the release of "danger" signals by the damaged cells that may induce activation of the immune cells. We have also established a parallelism between this IFN signature and alterations of tubular cells proliferation. Indeed, 2 days after Nx, we observed an activation of p21 in the tubular cells associated with a likely G1/S blockade of proliferating cells. Our results suggest that this cell cycle arrest affects the proliferation rate of tubular cells and underlies a trend for renal hypertrophy in FVB mice during the renal compensation phase. This first work pointed to a potential link between cellular and molecular processes occurring early after Nx, during the compensation phase, and the subsequent progression towards CKD in FVB mice. In a second work investigating the temporal and differential expression of YAP in the Nx model in FVB and B6 mice, we showed that the nuclear expression of YAP in podocytes was maintained and even increased in the “resistant” mice, and decreased significantly in "sensitive" mice with a correlation between this expression and the severity of glomerular lesions. The specific knockdown of YAP, or of its paralogous TAZ, in the podocytes of initially "resistant" mice allowed to better determine their respective role in the adaptation of these cells to nephron reduction. YAP podocyte-specific inactivation is associated with: (i) the development of focal and segmental glomerulosclerosis lesions; (ii) an increase of glomerular apoptosis; (iii) an alteration of the architecture of podocytes cytoskeleton; and (iv) podocyte rarefaction responsible for albuminuria and deterioration of renal function. Surprisingly, TAZ podocyte-specific inactivation was not associated with glomerular lesions. Contrary to TAZ, YAP plays a crucial role in podocyte adaptation to nephron reduction

Full textInsulin resistance is a major feature of the metabolic syndrome whose incidence is increasing in industrialized countries, in parallel with the obesity epidemic. Insulin resistance is associated with various cardiac, vascular and renal damages. The main objective was to evaluate the influence of sodium modulation (excess or restriction) on cardio-renal changes in a model of insulin resistance induced by fructose in rats. On one hand, the influence of salt restriction concomitant with a high fructose diet was evaluated. We have shown that sodium restriction prevents cardio-renal damages. These beneficial effects were associated with a reduction in renal inflammation and oxidative stress. In addition, a prevention of adipose tissue changes induced by fructose-rich diet was also obeserved. On the other hand impact of insulin resistance in presence of an early (weaning) sodium and excessive consumption of sodium was evaluated. When insulin resistance (fructose diet) was initiated secondary to high salt diet, cardiac hypertrophy associated with sodium diet decreased after the addition of insulin resistance. This paradoxal result could represent a maladaptation of cardiac muscle confirmed the impaired systolic function. In conclusion this work further demonstrates the impact of nutrition in the modulation of target organ damage. Reducing sodium intake may provide an easy way to reduce target organ damage observed in insulino resistance

Full textKidney disease affects about 5 million people in France mostly due to the increase in life expectancy and the evolution of our lifestyles (sedentary living, diet). Patient management is currently largely ineffective due to late diagnosis and our lack of understanding of the complex mechanisms that govern its progression. The study of the urinary proteome has emerged as an excellent way to discover biomarkers of nephropathies and thus to better understand the underlying pathophysiological mechanisms. Systems biology allows the molecular information contained in urine to be used to understand the overall organization of the regulatory networks in the diseased kidney tissue. In my thesis we have applied systems biology with two aims : The first aim was to improve the understanding of the pathophysiological mechanisms of kidney disease based on the analysis of urine molecular composition. Since the information in urinary proteome is mainly limited to excreted proteins, it is essential to have bioinformatic analysis methods available to "trace back" the key proteins present in the kidney tissue, but not excreted in the urine. Since this type of method is not widely used in nephrology, I have developed a methodological tool to identify in silico new key actors in kidney disease from the analysis of the urinary proteome. This new tool, called PRYNT (PRioritization bY causal NeTworks), is based on the use of protein-protein interactions with a prioritization method to identify proteins in the network that preferentially interact with urinary protein biomarkers. The second aim of my thesis was to develop systems biology approaches for the detection and progression of kidney disease using the molecular composition of urine. We developed a quantitative approach to propose an answer to these questions. I then applied this approach to the analysis of the urinary metabolome and amniotic fluid peptidome. Modelling and statistical methods allowed in these contexts to predict the presence of kidney disease and its progression
