Texto completo da fonteNephronophthisis is an autosomal recessive disorder characterized by tubular atrophy, thickened basement membranes, and the development of medullary cysts which arise via unknown mechanisms and ultimately lead to end-stage renal disease. Thus far, 9 disease genes (NPHP1-9) have been identified which encode the nephrocystins, all of which have been localized at cell-cell junctions, primary cilia, and centrosomes. Using shRNA-mediated knockdown of either NPHP1 or NPHP4 in MDCK cells, we demonstrate that the nephrocystins play an essential role in the establishment of apico-basolateral polarity by virtue of their interaction with the known tight junction proteins PALS1 and PATJ. Moreover, we identified a novel ciliary gene RPGRIP1L/NPHP8 which mutations can cause the multiorgan syndromes ol either Joubert syndrome type B (characterized by cerebellar vermis aplasia, retinal degeneration and nephronophthisis) or Meckel syndrome, an embryonic lethal syndrome characterized by renal cystic dysplasia, central nervous system malformations and hepatic developmental defects. RPGRIP1L encodes a cytosolic protein which colocalizes at the centrosome/primary cilia complex with nephrocystin-4 and nephrocystin-6 in MDCK cells, suggesting that RPGRIP1L and the other nephrocystins are involved ir similar signalling patways

Texto completo da fonteLe rein profond correspond aux structures médullaires, vasculaires post-glomérulaires, et à l’urothélium intrarénal. Cette définition regroupe des acteurs de la physiologie rénale dont l’étude est parfois difficile du fait de leur localisation. La fonction de concentration en particulier se rattache directement à ces structures profondes. L’objet de l’étude est donc une approche physiopathologique des altérations du rein profond, qu’elles soient à l’origine de la pathologie rénale, ou qu’elles en soient le reflet. La première partie du travail repose sur des données épidémiologiques de patients atteints d’une maladie rénale chronique et montre que la diminution de l’osmolalité urinaire à jeun est prédictive d’une dégradation du débit de filtration glomérulaire et d’une insuffisance rénale terminale chez ces patients. La deuxième étude porte sur le rôle des capillaires péritubulaires d’une part dans l’hémodynamique rénale, d’autre part dans l’apparition des lésions tubulaires. Dans un modèle d’hypertension artérielle, le rôle des capillaires péritubulaires dans la toxicité rénale de l’hème y est précisé. Enfin, la troisième partie concerne la structure la plus profonde du rein, l’urothélium intrarénal. Des données de la littérature laissant entrevoir son rôle potentiel dans les fonctions rénales, un modèle murin transgénique d’ablation conditionnelle de l’urothélium a été mis au point. L’osmolalité urinaire était diminuée et l’urée et la créatininémie étaient augmentées après ablation des cellules urothéliales. Ces résultats suggèrent un rôle de l’urothélium intrarénal dans la fonction de concentration des urines ; son rôle en physiopathologie doit encore être précisé

Texto completo da fonteChronic Kidney Disease (CKD) is defined, regardless of its primary cause, by the presence, for more than 3 months, of markers of kidney damage or a decrease in estimated glomerular filtration rate below 60 ml/min/1.73 m². CKD is associated with an increased risk of progression to end-stage renal disease as well as decreased patient survival. Therapeutic options remain limited and rely primarily on dialysis and renal transplantation.This thesis project aims at identifying novel molecular and cellular determinants associated with CKD and its complications based on different clinical entities. On the one hand, the search for genetic factors involved in the pathogenesis of certain hereditary nephropathies such as nephronophthisis or Alport syndrome has been addressed using innovative analytical techniques such as high-throughput sequencing. On the other hand, the involvement of a particular microRNA, miR-21, was evaluated in a mouse model of secondary nephropathy where kidney damage is induced by exposure to an anticancer agent, cisplatin. Our results allowed the identification of new genetic variants playing a causal role in Alport syndrome and nephronophthisis using an analytical strategy enabling complete genome sequencing. Furthermore, our data also suggest that miR-21 has a nephroprotective role and that its pharmacological modulation may prevent the occurrence of chronic renal failure in patients receiving chemotherapy including platinum derivatives. Overall, the results obtained in this work provide a better understanding of the pathophysiology of chronic kidney disease and could lead to new therapeutic options in the more or less long term

Texto completo da fonteNephroprotection has become a critical challenge during chronic or acute renal disease management. In order to enlight new therapeutic targets, we have documented the role of bradykinin B1 and B2 receptors (B1R, B2R) during diabetic nephropathy and endotoxin shock. During diabetic nephropathy, renin-angiotensin system blockade slows the progression of the disease. Using two models of diabetes in rat and mice, we have observed that B2R activation is largely involved in this protective effect. We next investigated the role of B1R and B2R in the development of renal failure during lipopolysaccharide (LPS)-induced endotoxin shock in wild-type or mice deficient for either the B1R or the B2R. Even if further investigations are needed, B2R activation contributes to the initial decrease in blood pressure, whereas the inactivation of B1R appears detrimental. Our results support the hypothesis of a protective role of B2R activation, particularly in chronic situation

Texto completo da fonteThe proximal tubule is involved in diuresis by modifying the content of the glomerular ultrafiltrate. Using a variety of transepithelial transports systems, it reabsorbs all ultrafiltrated glucose, amino-acids and low molecular weight proteins, as well as 80% of HPO42- and HCO3- ions, about 60% of Na+, Cl-, K+, and Ca2+ ions, 75% of water and 30% of Mg2+.During this thesis, I determined the physiological and physiopathological roles of two transport proteins present in proximal tubule. Firstly, I evaluated the renal function of mice invalidated for the Kir4.2 protein, whose role was undetermined. Our results show that Kir4.2, in association with Kir5.1, form a Kir4.2/Kir5.1 potassium channel at the basolateral membrane of proximal tubular cells. Furthermore, Kir4.2-null mice exhibit a reduced ammoniagenesis leading to an isolated proximal renal tubular acidosis. This study provides the gene encoding Kir4.2 as a candidate gene for the yet unexplained autosomal dominant isolated proximal renal tubular acidosis.Secondly, I evaluated in vitro the functional consequences of a pathogenic mutation of the 2Cl-/H+ exchanger ClC-5, involved in Dent’s disease. This disease, characterized by a low-molecular-weigth-proteinuria in the context of a general proximal tubule dysfunction, is currently thought to be due to an acidification defect of early endosomes linked to a loss of function of ClC-5. Surprisingly, our results show that ClC-5, converted into a chloride channel by this mutation, indeed acidifies the early endosomes as well as the ClC-5 wild-type. Thus, Dent’s disease may originate from a defect in the accumulation of chloride ions into the early endosomes

Texto completo da fonteComplement alternative pathway is physiologically activated. It need to be tightly regulated to avaoid uncontrolled deleterious overactivation on host cell surface. In human, two renal diseaes are associated with uncontrolled AP activation, hemolytic uremic syndrom atypical (aHUS) and C3 glomerulopathy (C3G). C3G occures mainly in children and young adults and regoups two distinct histopathological entities, dense deposit disease (DDD) and C3 glomerulonephritis (C3GN). Renal outcomes in C3G is poor since up to 50% of patients reach end stage renal disease 8 to 10 years after diagnosis. Complement abnormalities in C3G are mainly acquired induced by the presence of C3 Nephritic Factor (C3NeF): an autoantibdy targeting the AP C3 convertase. Less frequently C3G patients have anti-FH autoantibodies (Ref) or genetic abnormalities (variants in the FH, FI or CFHR5 genes. In silico analysis of mutated proteins give information about the role of mutation on AP overactivation. However, characterization of functional consequences of these mutations is required to proved the direct link between the abnormality and the occurrence of C3G. I first studied the functional consequences of the first C3 mutation, C3I734T, identified in a familial C3GN. In silico analysis revealed that the mutated residue, T734, is located on the C3 and C3b protein surface and that the substitution I734T may not be associated with major structural changes. The mutated amino acid is located on interaction site between C3b and complement regulatory proteins, FH and CR1. In vitro, the major defect of C3I734T was a decrease in binding to CR1, resulting in lower CR1 dependent cleavage of C3b by FI. These results provide evidence for a CR1 functional deficiency being responsible for deficient complement regulation. Binding of C3I734T to Factor H (FH) was normal, but C3I734T was less efficiently cleaved by Factor I, leading to enhanced C3 fragments binding on glomerular cells. In the second part of my work, I studied acquired C3G in patients with concomitant monoclonal gammopathy. In the clinical part of this study, we demonstrated The high prevalence of monoclonal gammopathy in C3G patients aged over 50, reaching 65% in the French C3G national cohort, strongly suggests a pathogenic link between the two conditions. Next, we demonstrated that renal outcomes is significantly worser in patients with monoclonal gammopathy compared to patients without monoclonal gammopathy but that efficient chemotherapy resulted in higher renal response rate and longer renal survival than conservative or immunosuppressive therapy. Results of the clinical part of the study strongly suggest a link betwwen the monoclonal gammopathy and the occurrence of C3G. In the experimental part of this work, I studied the mechanisms of complement AP activation in these population. Biomarkers of C3 and C5 convertase activation were present 40% and 81% of patients respectively. Anti-complement protein antibodies were found in 23/41 (56%) patients, including in most of patients, anti-FH and anti-CR1 antibodies. I found new antigenic target, C5 and properdin in few cases. The anti-FH and anti-CR1 antibodies were associated with clear functional consequences. Nevertheless, the anti-complement proteins reactivity was not carried out by the MIg in 75% of the cases. I discovered that the MIg induced a direct AP C3 convertase overactivation in 23/34 (67%) patients responsaible for a C5 convertase overactivation in presence of patients’ Ig, in a properdin dependant manner. Our results suggest that MIg and polyclonal autoantibodies could act in synergy: AP overactivation induced by the MIg could be amplified by the inefficient complement regulation, caused by the polyclonal anti-complement autoantibodies. All my results allow to better understand the pathophysiological mechanisms involved in C3G and open up reflection on therapeutic approaches for C3G associated with monoclonal gammopathy

Texto completo da fonteAcute Kidney Injury (AKI) is strongly associated with mortality independently of its cause. The kidney contributes to up to 40% of systemic glucose production by gluconeogenesis during fasting and stress conditions. Whether kidney gluconeogenesis is impaired during AKI and how this might influence systemic metabolism remains unknown. Here we show that glucose production and lactate clearance are impaired during human and experimental AKI using renal arteriovenous catheterization in patients, lactate tolerance test in mice and glucose isotope labelling in rats. Single-cell transcriptomics reveal that gluconeogenesis is impaired in proximal tubule cells during AKI. In a retrospective cohort of critically ill patients, we demonstrate that altered glucose metabolism during AKI is a major determinant of systemic glucose and lactate levels and is strongly associated with mortality. Thiamine supplementation increases lactate clearance without modifying renal function in mice with AKI, enhances glucose production by renal tubular cells ex vivo, and is associated with reduced mortality and improvement of the metabolic pattern in a retrospective cohort of critically ill patients with AKI. This study highlights an unappreciated systemic role of renal glucose and lactate metabolism in stress conditions, delineates general mechanisms of AKI-associated mortality and introduces a potential intervention targeting metabolism for a highly prevalent clinical condition with limited therapeutic options
