Abstract:
Brain angiotensin II receptors were located in 18-day-old rat embryos by quantitative autoradiography. In the nucleus of the solitary tract and choroid plexus, binding was displaced by the type-1 antagonist DuP 753. In the inferior olive, paratrigeminal and hypoglossal nuclei, binding was displaced by the type-2 antagonist CGP 42112 A. Meninges and cephalic soft tissues contained predominantly type-2 angiotensin II receptors. Our results indicate a role for type-1 and type-2 angiotensin II receptors during brain development.
