Adeno-associated virus (AAV) is a promising in vivo gene delivery platform showing advantages in delivering therapeutic molecules to difficult or undruggable cells. However, natural AAV serotypes have insufficient transduction specificity and efficiency in kidney cells. Here, we developed an evolution-directed selection protocol for renal glomeruli and identified what we believe to be a new vector termed AAV2-GEC that specifically and efficiently targets the glomerular endothelial cells (GEC) after systemic administration and maintains robust GEC tropism in healthy and diseased rodents. AAV2-GEC-mediated delivery of IdeS, a bacterial antibody-cleaving proteinase, provided sustained clearance of kidney-bound antibodies and successfully treated antiglomerular basement membrane glomerulonephritis in mice. Taken together, this study showcases the potential of AAV as a gene delivery platform for challenging cell types. The development of AAV2-GEC and its successful application in the treatment of antibody-mediated kidney disease represents a significant step forward and opens up promising avenues for kidney medicine.

Background And Aims: Early prevention of chronic kidney disease is critical. We aimed to identify predictive risk factors for early-stage renal dysfunction.
Methods And Results: This retrospective study analyzed specific health checkup data from the general Japanese population.

Body temperature regulation in endotherms requires warming the body when ambient temperatures are low and cooling the body when they are high. Now, neural circuitry that can achieve the opposite has been identified - a phenomenon called thermoregulatory inversion.

Background: Cisplatin-induced acute kidney injury (CKI) represents a severe renal dysfunction characterized by DNA damage and tubular injury. Fraxetin, derived from the Chinese herb Qinpi (Fraxinus bungeana A.DOC), is recognized for its neuroprotective effects and has been used for the prevention of various diseases.

Introduction: This study aimed to investigate the association between trajectories of depressive symptoms and the subsequent risk of chronic kidney disease (CKD) by measuring depressive symptoms repeatedly in older adults with normal renal function.
Methods: A total of 9650 participants, comprising community-dwelling middle-aged and older adults from the China Health and Retirement Longitudinal Study, were included. Depressive symptoms were assessed at three time points: Wave 1 (2011-2012), Wave 2 (2013-2014), and Wave 3 (2015-2016).

SIRT6 is known to play a protective role in several kidney diseases; however, its role in vancomycin-induced renal injury remains unclear. This study aims to confirm the role and related mechanisms of SIRT6 in vancomycin-induced renal injury. To develop a kidney damage model, mice were given vancomycin injections for seven days.
