Signaling crosstalk angiotensin II receptor subtypes and insulin

Abstract

Insulin-resistant states are often associated with hypertension, and the accumulated data indicate that ARB decrease new-onset of diabetes with vasoprotective effects. Recent evidence suggests that activation of Ang II receptor subtypes could regulate insulin sensitivity at multiple sites of insulin signaling in various diabetic animal models and regulate vascular remodeling in concert with insulin in potentially distinct fashions. Moreover, the roles of Ang II receptor subtypes have been highlighted in insulin resistance in obesity, which is one of the major risk factors for the development of hypertension. More detailed analysis of the crosstalk of Ang II and insulin-mediated signaling in various tissues would provide further information to understand the clinical relevance of the effect of ARB on insulin resistance, thereby preventing cardiovascular events associated with insulin resistance.
