Mechanosensing in the Renal Tubule: Ion Channels, Ca2+ Signaling, and the Integration of Mechanical Cues along the Nephron

This review explores how renal tubular epithelia sense and respond to mechanical forces along the nephron, particularly in distal segments where mechanosensitive ion channels are abundant. The authors aim to elucidate the mechanisms by which tubular cells decode various mechanical cues, such as tangential drag and circumferential wall tension, and how these signals are integrated into specific physiological responses through compartmentalized Ca2+ signaling. Additionally, the review highlights the pathological implications of disrupted mechanosensing in conditions like autosomal dominant polycystic kidney disease.
