Congenital Anomalies of the kidney and urinary tract: pediatric origins and adult outcomes

Sep 22, 2026

The authors investigate the origins and long-term outcomes of congenital anomalies of the kidney and urinary tract (CAKUT), which are significant contributors to pediatric chronic kidney disease (CKD). They emphasize the importance of genetic testing and a life-course model of care to manage CAKUT effectively, highlighting the increased risks of cardiovascular, metabolic, and neurocognitive issues in affected individuals as they transition into adulthood.

A comprehensive proteomic and transcriptomic mapping study found porcine and human kidneys exhibit a profoundly altered biological profile during warm ex vivo perfusion

Sep 22, 2026

The authors aimed to investigate the molecular changes occurring in porcine and human kidneys during normothermic machine perfusion (NMP) and how these changes differ from in vivo physiology. Their comprehensive proteomic and transcriptomic analysis revealed extensive transcriptional reprogramming and gradual proteomic alterations, indicating that NMP induces significant biological remodeling that cannot be solely attributed to donor characteristics. This study highlights the need to consider ex vivo-specific responses when assessing kidney viability during perfusion, challenging the reliance on in vivo biomarkers.

Donor and recipient immune programs underlying delayed graft function in kidney transplantation revealed by temporal single-cell profiling

Sep 22, 2026

The authors aimed to elucidate the immune mechanisms underlying delayed graft function in kidney transplantation, particularly distinguishing the immune responses associated with deceased versus living donor kidneys. Through single-cell RNA sequencing and spatial transcriptomics, they identified distinct immune profiles in donor and recipient cells that contribute to the inflammatory responses observed in delayed graft function. Their findings highlight specific cellular circuits and immune programs that could inform strategies to improve transplant outcomes.

Large-scale organoid-derived cyst cultures as a drug discovery platform for polycystic kidney disease

Sep 22, 2026

The authors aim to establish a scalable platform using ureteric bud (UB) organoids derived from human induced pluripotent stem cells (hiPSC) for drug discovery in autosomal dominant polycystic kidney disease (ADPKD). They successfully generated cyst-forming UB organoids that mimic the disease and screened a small-molecule library, identifying compounds that reduce cyst size, thereby validating the organoid model as a promising tool for developing ADPKD therapies.

Whole-genome sequencing characterizes monogenic and polygenic contributions to structural kidney and urinary tract malformations

Sep 21, 2026

The authors aimed to characterize the genomic architecture of congenital anomalies of the kidneys and urinary tract (CAKUT) using whole-genome sequencing (WGS) in a cohort of 1,052 individuals. They found a low overall diagnostic yield of 4.9% for monogenic causes, with certain clinical features predicting higher rates, while common and low-frequency variants were estimated to explain 23% of the phenotypic variance, suggesting these variants may contribute to the heritability of CAKUT.

Androgens Drive SOX9 Upregulation in Injured Proximal Tubular Cells

Sep 21, 2026

The authors investigate whether the transcription factor SOX9 mediates sex-specific responses in proximal tubular cells following acute kidney injury (AKI) in male and female rodent models. They find that SOX9 upregulation and its protective effects are significantly more pronounced in males, driven by testosterone, while females exhibit a blunted response. This study highlights the necessity for sex-inclusive approaches in developing therapeutic strategies for AKI, given the distinct injury and recovery pathways identified between sexes.

Automated chemiluminescence immunoassay for the detection of anti-nephrin autoantibodies

Sep 21, 2026

The authors aimed to develop a standardized automated chemiluminescence immunoassay (CLIA) for detecting anti-nephrin autoantibodies, which are important in autoimmune podocytopathies like minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS). Their study demonstrated that the CLIA showed high concordance with existing methods and detected anti-nephrin IgG more frequently, suggesting its potential for clinical application in disease stratification and monitoring. The findings indicate that elevated anti-nephrin IgG levels are associated with worse clinical outcomes, including increased relapse risk in patients.

Cadherin-11 and the mechanobiology of the fibrogenic niche

Sep 18, 2026

The authors investigate the role of cadherin-11 in kidney fibrosis, specifically whether it drives the disease process. They demonstrate that blocking cadherin-11, either genetically or with antibodies, can reduce fibrosis, maintain renal function, and prevent the stiffening of the fibrogenic niche across multiple injury models, suggesting that cadherin-11 influences fibroblast activation through its impact on cellular mechanics.

Frailty in children with chronic kidney disease and kidney failure

Sep 18, 2026

The authors aim to address the under-recognition of frailty in children with chronic kidney disease, emphasizing that it manifests as a loss of developmental potential rather than functional decline. They advocate for early identification through standardized screening to facilitate timely interventions, highlighting the potential for reversibility in childhood frailty, which can enhance developmental outcomes and resilience.

Comprehensive geriatric assessment for older people living with chronic kidney disease and frailty: time to set a new goal?

Sep 18, 2026

The authors investigate whether comprehensive geriatric assessment (CGA) improves goal attainment for older adults with chronic kidney disease and frailty, following findings from the GOAL trial that indicated no significant benefits from a single outpatient appointment with a geriatrician. They suggest that alternative models of CGA and person-centered care should be explored, emphasizing the importance of integrating person-centered approaches into nephrology services.
