Interaction of the renal amylin and renin-angiotensin systems in animal models of diabetes and hypertension

Abstract

The range of known actions of amylin are reviewed together with the proposal that an important role for amylin may be the hormonal integration of diverse physiological systems activated with feeding. Major targets for the action of amylin are found within the kidney. Components of the amylin system (AS) have been shown to influence the activity of components of the renin- angiotensin system (RAS), and vice versa, in normal, hypertensive and diabetic models. For instance, amylin injected into humans and rats elicits a rapid rise in plasma renin activity. Furthermore, in two models of hypertension (the spontaneously hypertensive rat (SHR) and the model with subtotal nephrectomy (STNx), the den..
