Abstract
The present study demonstrates the existence and regional distribution of angiotensin II AT1 receptor subtype mRNA expression in the rat brain by the use of in situ hybridization and RNase protection assay. Substantial expression levels in the brain have only been detected in certain distinct areas, such as the subfornical organ, the parvocellular part of the paraventricular hypothalamic nucleus, and the median preoptic nucleus. The results give further evidence for the involvement of the angiotensin II AT1 receptor subtype in the classical functions of central angiotensin II, like blood pressure control, body fluid homeostasis and in corticotropin-releasing factor (CRF) secretion.
