Decreased angiotensin II receptors in subfornical organ of spontaneously hypertensive rats after chronic antihypertensive treatment with enalapril.

Angiotensin II (ANG II) receptor density was higher in many brain regions of untreated spontaneously hypertensive rats (SHR) compared to untreated Wistar-Kyoto (WKY) animals. Systemic inhibition of angiotensin converting enzyme with enalapril (25 mg/kg, per os for 14 days) produces a large decrease in ANG II receptors localized exclusively in the subfornical organ (SFO) of the SHR, and no alterations in ANG II receptors in the normotensive WKY rats. Selective decrease of ANG II receptors in the SFO of the genetically hypertensive rats with enalapril may be related to its therapeutic efficacy.
