Sodium and chloride homeostasis

Sodium and chloride homeostasis comprises the integrated control of sodium and chloride ion concentrations across various body compartments. This regulation is essential for maintaining fluid and electrolyte balance, blood pressure, membrane potential, nerve and muscle function, and acid-base status. The kidneys, via the action of ion channels (ENaC, ClC family, CFTR), cotransporters (NCC, NKCC), and pumps (Na⁺/K⁺-ATPase), as well as systemic hormonal signaling (renin-angiotensin-aldosterone system, ADH/vasopressin, natriuretic peptides), play a central role in this homeostasis. Imbalances in sodium or chloride can give rise to serious clinical syndromes, including disturbances in blood pressure, neurological function, kidney injury, and acid-base status[1][3][5][6][7][4][2][9][8]. Because "Sodium and chloride homeostasis" is a physiological process, not a molecule or canonical therapeutic target, it should not be entered as a drug target in structured datasets. Instead, individual mediators (receptors, transporters, channels, enzymes) responsible for Na⁺/Cl⁻ regulation should be separately classified and annotated.
