Should not alter clinical practice; leaves open validation of ANP receptor distribution in human cardiovascular regulation.
The study maps the specific tissue receptors for atrial natriuretic peptide in rats, highlighting its role in blood pressure and fluid homeostasis.
Tjälve et al. (1988) studied this question. 125I-labelled α-r-atrial natriuretic peptide vs. Simultaneous injection of an excess of non-labelled α-rANP was evaluated on Distribution of radioactivity in tissues. Intravenous administration of [125I]α-rANP in rats showed rapid, specific localization in renal glomeruli, heart endocardium, and other tissues involved in blood pressure and fluid regulation.
