Full textFocal and segmental glomerulosclerosis (FSGS) is a serious disease, the pathogenesis of which is unknown. Its recurrence after transplantation (Tx) and its partial remission after treatment with immunoadsorption (IA) on a protein A column indicate the existence of a circulating factor (CF) responsible for the disease that is able to bind to a protein A column. Recently, the soluble receptor of urokinase (suPAR) was described as the factor responsible for FSGS. The first aim of my work was to test the capacity of suPAR to bind to protein A and to be eliminated by IA. The second aim was to identify the CF responsible of the recurrence of the disease after renal transplantation from the analysis of proteins eluted from protein-A columns from patients with rFSGS who had undergone therapeutic (IA). First, we measured suPAR in eluates of protein A columns from 7 patients with recurrent FSGS after Tx (rFSGS) treated with IA, and in the serum of 13 patients with rFSGS and 11 healthy donors (HD). Additionally, the plasma of these patients was immunoadsorbed in vitro on a protein A Sepharose column and we quantified suPAR in the eluates and in pre- and post-column samples. The concentration of suPAR was higher in the plasma of patients with rFSGS than in the plasma of HD patients. However, the concentration of suPAR was similar before and after IA on protein A for the rFSGS and HD samples. The suPAR concentration was very low in the eluates from protein A columns incubated with plasma from HD or rFSGS patients. However, 85% of rFSGS patients showed a decrease in immunoglobulin G and proteinuria. Secondly, we analyzed proteins eluted from protein-A columns from patients with rFSGS who had undergone therapeutic immunoadsorption. Compared to control a differential band was identified by mass spectrometry. The expression of this protein was tested by immunochemical methods in sera from healthy controls, from patients with proteinuria caused by diabetic nephropathy, and from rFSGS patients. The effect of the recombinant protein was evaluated in vitro (podocytes) and in vivo experiments (mice). A soluble form of calcium/calmodulin-dependent serine/threonine kinase (CASK) eluted from protein-A columns was identified by mass spectrometry. CASK was immunoprecipitated only in the sera from patients with rFSGS. Recombinant CASK induced reorganization of the actin cytoskeleton of cultured podocytes through an interaction with CD98 at the cell surface. In vitro, CASK increased the permeability of podocyte monolayers, and induced proteinuria and foot-process effacement in miceIn conclusion, suPAR does not significantly bind to protein A in vitro or in vivo. Soluble CASK acts as a permeability factor in patients with rFSGS bindinding CD98 on podocytes

Full textFocal segmental glomerulosclerosis (FSGS) is often associated with a high rate of progression to end-stage renal disease. The idiopathic form has a high recurrence rate (rFSGS) after transplantation suggesting the presence of a systemic circulating factor that causes the glomerular permeability. This factor can be removed by plasmapheresis or immunoadsorption using protein-A columns. We used mass spectrometry to analyze the proteins eluted from protein-A columns, taken from patients with rFSGS after immunoadsorption. A serum form of calcium/calmodulin-dependent serine/threonine kinase (CASK) was identified in rFSGS patients but not in controls. In cultured podocytes, recombinant CASK induced reorganization of the actin cytoskeleton. We also demonstrated the interaction of CASK with CD98 at the cell surface. Injection of recombinant CASK in mice induced proteinuria and foot process effacement on podocytes. We identified that CASK is produced by monocytes in patients with rFSGS. CASK is also expressed and secreted by M2 polarized macrophages but not by M1 subset. CASK was associated with exosomes produced by these cells. CASK has a partial codistribution with ALIX, an exosomal component involved in their development. We’ve also demonstrated that CASK interacts with ALIX in M2 macrophages. Moreover exosomes derived from M2 macrophages cause podocytes cytoskeleton alterations and increase of podocyte motility as observed previously with recombinant CASK. In conclusion, a serum form of CASK secreted by macrophages acts as a permeability factor in patients with rFSGS suggesting its involvement in the physiopathology of rFSGS

Full textThe mechanisms driving the development of extracapillary lesions in focal segmental glomerulosclerosis (FSGS) and crescentic glomerulonephritis (CGN) remain poorly understood. A key question is how parietal epithelial cells (PEC) invade glomerular capillaries, thereby promoting injury and kidney failure. Here we show that expression of the tetraspanin CD9 increases markedly in PEC in mouse models of CGN and FSGS, and in kidneys from individuals diagnosed with these diseases. Cd9 gene targeting in PEC prevents glomerular damage in CGN and FSGS mouse models.Mechanistically, CD9 deficiency prevents the oriented migration of PEC into the glomerular tuft and their acquisition of CD44 and β1 integrin expression. These findings highlight a critical role for de novo expression of CD9 as a common pathogenic switch driving the PEC phenotype in CGN and FSGS, while offering a potential therapeutic avenue to treat these conditions

Full textGlomerular diseases are a leading cause of kidney failure and represent a public health problem. Classically, systemic effectors such as the immune system, drug toxicity or hypertension are thought to be the main drivers of glomerular diseases. The hypothesis developed in this manuscript is that epithelium and endothelium, the two main components of the renal parenchyma, are major players in the formation of glomerular lesions. Three experimental models of glomerular disease (inflammatory, toxic and hypertensive) in mice allowed us to study epithelial γC / JAK / STAT signaling classically described in immune cells and the endothelial hypoxia inducible system in order to support this hypothesis. After discussing the main role traditionally assigned to T cells in the anti- glomerular basement membrane model, an animal model of inflammatory glomerulonephritis, we demonstrated the protective role of the glomerular interleukin common γ chain (γC) receptor and its dependent podocyte-specific STAT5 during the anti-GBM model and adriamycin nephropathy. We then showed the protective role of endothelial EPAS1 (HIF-2α), a regulatory subunit of HIF complex in focal segmental glomerulosclerosis (FSGS) induced by angiotensin II. In total, this work highlights the important role of the closely linked renal epithelium and endothelium in the formation of glomerular lesions using three experimental models of glomerular diseases. The renal parenchyma is a full player in the pathophysiology of these lesions as shown by the works studying γC / JAK / STAT and HIF systems
