The treatment and management of kidney disease present a significant global challenge, affecting over 800 million individuals and necessitating innovative therapeutic strategies that transcend symptomatic relief. The application of nanotechnology to renal therapies, while still in its early stages, holds transformative potential for improving treatment outcomes. Recent advancements in nanoparticle-based

BACKGROUND Hemodialysis (HD) contributes significantly to healthcare's carbon footprint. Worldwide about 100,000 dialysis machines end their life cycle each year. Our aim was to analyze the composition and the potential for recyclability of two dialysis machines, from the two companies with the largest market share, which had met their end-of-use terms (10-12 years of use according to French regulations)

BACKGROUND Structure and function in the mammalian kidney are organized along a radial axis highlighted by the corticomedullary organization and regional patterning of the collecting system. The arborised collecting epithelium arises through controlled growth, branching and commitment of Wnt11+ ureteric progenitor cells within cortically localized branch tips until postnatal day 3. METHODS We applied

BACKGROUND Acute kidney injury (AKI) is recognized as a common risk factor for chronic kidney disease (CKD). Renal tubular epithelial cell polyploidization after AKI is closely associated with maladaptive repair, while the regulatory and molecular mechanisms remain poorly understood. Here, we set out to investigate the mechanism of tubular epithelial cell polyploidization and their role in the AKI-to-CKD

BACKGROUND The P2X7 ion channel, a key sensor of sterile inflammation, has been implicated as a therapeutic target in glomerulonephritis, and P2X7-antagonistic nanobodies can attenuate experimental glomerulonephritis. However, little is known about the expression of P2X7 on renal immune cells. METHODS We used conventional immunofluorescence of kidney sections as well as intraperitoneal injection of

BACKGROUND Nephrology is one of the pediatric subspecialties with the largest workforce shortage in the US. Waitlist registration is one of the first steps towards kidney transplantation and is facilitated by pediatric nephrologists. The objective of this study was to determine whether state-level density of pediatric nephrologists is associated with access to waitlisting (primary outcome) or kidney

BACKGROUND Loss of function mutations in the lysosomal channel TRPML-1 cause mucolipidosis type IV (MLIV), a rare lysosomal storage disease characterized by neurological defects, progressive vision loss, and achlorhydria. Recent reports have highlighted kidney disease and kidney failure in patients with MLIV during the second to third decade of life; however, the molecular mechanisms driving kidney

Planetary health encompasses the understanding that the long-term well-being of humanity is intrinsically linked to the health of global ecological systems. Unfortunately, current practices often overlook this principle, leading to a human-oriented (anthropocentric) worldview that has resulted in heightened greenhouse gas emissions, increased heat stress, lack of access to clean water and pollution

Megalin is an endocytic receptor in the proximal tubules that reabsorbs filtered proteins in the kidneys. Recycling of megalin after endocytosis and its expression on the apical plasma membrane of the proximal tubule are critical for its function. The expression of megalin in the kidney undergoes dynamic changes under physiologic and pathophysiologic conditions. Receptors and various effector signaling

BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is characterized by mutations in either the Pkd1 or Pkd2 genes leading to progressive cyst growth and often kidney failure. We have previously demonstrated that tubules can enlarge following loss of Pkd1 without an increase in tubular cell numbers, suggesting that tubular basement membrane remodeling is important for cystic dilation. RNA

BACKGROUND Lowering blood pressure (BP) in persons with low diastolic BP could be harmful. Hence, we examined whether baseline diastolic BP modifies the effects of BP lowering on clinical outcomes in a meta-analysis of five large BP lowering trials. METHODS In a study-level meta-analysis based on individual participant data of the Systolic Blood Pressure Intervention Trial (N = 9361), the Action to

BACKGROUND Accurate diagnosis of acute tubulointerstitial nephritis (AIN) often requires a kidney biopsy. We previously developed a diagnostic statistical model for predicting biopsy-confirmed AIN by combining four laboratory tests after evaluating over 150 potential predictors from the electronic health record. Here, we validate this diagnostic model in two biopsy-based cohorts at Johns Hopkins Hospital

BACKGROUND Atrial fibrillation is common in individuals receiving dialysis. The role of oral anticoagulation in this population is uncertain given its exclusion from previous seminal clinical trials. Our objective was to determine the feasibility of performing a large definitive trial to establish the optimal anticoagulation strategy in individuals with atrial fibrillation receiving dialysis. METHODS

BACKGROUND Gaps in guideline-concordant care for chronic kidney disease (CKD) lead to poor outcomes. The Kidney Coordinated HeAlth Management Partnership (K-CHAMP) cluster randomized trial tested the effect of a population health management intervention versus usual care on CKD progression and evidence-based care delivery in the primary care setting. METHODS K-CHAMP included adults aged 18-85 years

BACKGROUND This analysis evaluated the efficacy and safety of sotagliflozin, a dual SGLT1&2 inhibitor, added to insulin in patients with type 1 diabetes and chronic kidney disease (CKD). METHODS We used data from the 52-week pooled inTandem1&2 trials and the 24-week inTandem3 trial to assess the effects of sotagliflozin (200mg [inTandem 1&2 only] or 400mg daily) versus placebo on glycated hemoglobin

BACKGROUND Patients with kidney failure are at elevated risk of cardiovascular diseases. Although statins were commonly used to mitigate cardiovascular disease risk among the population with high risk, the evidence for initiating statin therapy among patients with kidney failure remains inconclusive. This study aimed to investigate the long-term benefits and risks associated with statin therapy in

BACKGROUND Inhibitor of MyoD family A (I-mfa) is a cytosolic protein. Its function in kidney is unknown. The aim of the present study was to examine the regulatory role of I-mfa on glomerular filtration rate (GFR). METHODS GFR was measured by transdermal measurement of FITC-sinitrin clearance in conscious wild type (WT) and I-mfa knockout (KO) mice. Cell contractility was assessed in a single human

BACKGROUND Damages to subcellular organelles, such as mitochondria and endoplasmic reticulum, are well-recognized in tubular cell injury and death in acute kidney injury (AKI). However, the changes and involvement of Golgi apparatus are much less known. Here, we report the regulation and role of N-acetylgalactosaminyltransferase-3 (GALNT3), a key enzyme for protein glycosylation in Golgi apparatus

BACKGROUND The renal epithelial sodium channel (ENaC) is essential for sodium balance and blood pressure control. ENaC undergoes complex proteolytic activation by not yet clearly identified tubular proteases. Here, we examined a potential role of transmembrane serine protease 2 (TMPRSS2). METHODS Murine ENaC and TMPRSS2 were (co-)expressed in Xenopus laevis oocytes. ENaC cleavage and function were

BACKGROUND The Piezo gene encodes a highly conserved cell membrane protein responsible for sensing pressure. The glomerular kidney and the slit diaphragm filtration structure depend on pressure for filtration. However, how Piezo is involved in kidney function and in maintaining the slit diaphragm filtration structure is not clear. METHODS We used Drosophila pericardial nephrocytes, filtration kidney

BACKGROUND Long-term outcomes of rituximab-treated adult patients with podocytopathies (either minimal change disease or focal segmental glomerulosclerosis) are largely unknown. METHODS A retrospective study at 30 nephrology departments from 15 countries worldwide included rituximab-treated adults with primary podocytopathies and a minimum clinical follow-up of 36 months. The primary outcome was relapse-free

BACKGROUND Vaptans were developed at the end of the previous century as V2R antagonists. Tolvaptan is the most prescribed vaptan for hyponatremia and the autosomal polycystic kidney disease (ADPKD). However, its use is not as widespread as it should be due to price issues, a narrow therapeutic window and some side effects. With the aim of discovering new efficient and safer V2R antagonists, we screened
