α2-ADRENOCEPTOR CONSTRAINT OF CATECHOLAMINE RELEASE AND BLOOD PRESSURE IS ENHANCED IN FEMALE SPONTANEOUSLY HYPERTENSIVE RATS

Frontiers in Neuroscience, 2016
α2-adrenoceptors (α2AR) lower central sympathetic output and peripheral catecholamine release, and may therefore prevent sympathetic hyperactivity and hypertension. The α2AR are dysfunctional in male spontaneously hypertensive rats (SHR).
