Role of angiotensin II in chronic blood pressure control of heterozygous Ren-2 transgenic rats: Peripheral vasoconstriction versus central sympathoexcitation.

In conclusion, sympathoinhibition represents the main mechanism of BP reduction in heterozygous TGR rats subjected to chronic brain or systemic RAS blockade, while peripheral attenuation of angiotensin II-dependent vasoconstriction during systemic RAS blockade is less important. Our data suggest that the participation of angiotensin II in BP control of adult heterozygous TGR rats is shifted from peripheral vasoconstriction to central sympathoexcitation. Similar mechanisms cannot be excluded in human essential hypertension. PMID: 31132670 [PubMed - as supplied by publisher]
