Prostaglandin E2(PGE2) is a potent modulator of a wide variety of physiological responses including inflammation (1), gastric acid secretion (2), vascular tone (3), lipolysis (4) and water and ion transport (5). The rabbit kidney represents a well characterized physiological model with respect to PGE2effects. In the kidney, PGE2 has been shown to modulate glomerular hemodynamics (6) as well as water and ion transport in the thick ascending limb (7) and collecting duct. Under some circumstances the cellular effects of PGE2appear to be self-opposing. In the cortical collecting duct (CCD), PGE2causes stimulation of water reabsorption via increasing the intracellular level of cAMP (8,9) and suppression of arginine-vasopressin water reabsorption by inhibiting cAMP generation (8). Similarly PGE2has been shown to vasodilate certain vascular beds while it constricts other vascular beds (10,11,12). These self-opposing effects of PGE2appear to be mediated by separate classes of PGE2receptors (3).
