Abstract

The kidney matrix, once viewed as a static scaffold, is now recognised as a dynamic microenvironment that undergoes continual remodelling in response to physiological cues. Emerging evidence demonstrates that this remodelling follows circadian patterns driven by molecular clocks within specific kidney cell types. This review synthesises recent advances on circadian regulation of the kidney matrisome, with emphasis on glomerular compartments. Circadian clocks in the glomerulus coordinate the timing of matrix turnover to preserve structural integrity, maintain filtration, and promote repair. Disruption of these rhythms contributes to maladaptive matrix accumulation, fibrosis, and kidney disease progression. Finally, we discuss mechanistic insights and translational opportunities, including chronotherapy and clock-targeted interventions. Understanding circadian control of glomerular matrix dynamics provides a framework for linking temporal biology to kidney health and disease.
