title: Non-peptide angiotensin II receptor antagonists discriminate subtypes of 125I-angiotensin II binding sites in the rat brain.
abstract: We have utilized quantitative autoradiography to define subtypes of 125I-angiotensin II (AII) binding in rat brain. AII-1 binding (displaced by DuP 753) was found in the nucleus of the solitary tract and the hypothalamus, while AII-2 binding (displaced by WL 19) was found in the thalamus and lateral septum. These results indicate that subtypes of the AII receptor are present in the brain and the AII-1 receptor subtype is present in regions consistant with the known actions of angiotensin.
