title: Angiotensin II specific receptors in subcommissural organ.
abstract: In the subcommissural organ of male rats, a circumventricular organ situated inside the blood-brain barrier, specific receptors for angiotensin II were demonstrated by binding studies on homogenated membranes and by autoradiography carried out on frozen sections using 125I-angiotensin II. The receptor sites were localized in the subnuclear region of cells of the subcommissural organ. A single class of binding sites was found whose capacity was modulated by changes in the sodium plasma concentration which led to variations in plasma volume.
