Binding of 125I-[Sar1,Ile8]angiotensin II in the human hypothalamus was mapped by in vitro autoradiography carried out on frozen sections of hypothalamus from two human brains. Regions showing the greatest specific binding of this radioligand were the organum vasculosum of the lamina terminalis, median preoptic nucleus, subfornical organ, median eminence, arcuate nucleus and paraventricular nucleus. These regions may be sites of angiotensin II receptors involved in the regulation of blood pressure, fluid balance and pituitary hormone secretion.
