Abstract

Blood vessels isolated from bovine and human retinas have sites that specifically bind 3H-angiotensin II (3H-Ag II) with an apparent dissociation constant (Kd) of 14 nM and a capacity of binding (Bmax) of 0.82 pmol/g. The binding sites for 3H-Ag II appear to be influenced by guanine nucleotides (GTP) and cations (Mg2+ and Na+) in a way that resembles angiotensin II receptors in other tissues. The physiologic effect of blood-borne or locally-formed angiotensin II on retinal blood flow remains to be defined.
