Abstract

In recent years, our understanding of the physiology of the aldosterone-sensitive distal nephron (ASDN) has greatly advanced thanks to the discovery of the complex with-no-lysine kinase (WNK) signaling and the molecular characterization of the epithelial sodium channel (ENaC). A series of studies, initially focused on rare tubulopathies such as Gordon and Liddle syndromes, eventually led to a partial elucidation of the so-called “aldosterone paradox”, the traditional explanation of the physiology of such disparate conditions such as hyperkalemia and low effective arterial blood volume. The physiology of the ASDN is herein illustrated in light of the novel acquisitions in an easy-to-understand fashion, with the aim of giving the practicing nephrologist a solid “first glance” into this exciting but challenging field. Focus is on ion channels and transporters, their regulation by key hormones such as aldosterone and angiotensin II, and dietary implications.
