Although plasma levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are elevated early after myocardial infarction (MI), the significance is not fully understood. We therefore investigated the function of natriuretic peptides after induction of MI in knockout (KO) mice lacking the natriuretic peptide receptor guanylyl cyclase-A, the receptor for ANP and BNP. KO and wi...
Atrial natriuretic peptide (ANP) interacts with high-affinity, guanylyl cyclase-linked receptors in the inner medullary collecting duct (IMCD), where it exerts important regulatory control over sodium handling. We sought to determine whether receptor activity in these cells would be modulated (downregulated) by prolonged exposure to ligand. A number of natriuretic peptides (ANP, brain natriuret...
Atrial natriuretic peptide (ANP) and C-type natriuretic peptide (CNP) are important dilators of the pulmonary circulation during the perinatal period. We compared the responses of pulmonary arteries (PA) and veins (PV) of newborn lambs to these peptides. ANP caused a greater relaxation of PA than of PV, and CNP caused a greater relaxation of PV than of PA. RIA showed that ANP induced a greater ...
Natriuretic peptide receptor A (NPR-A/GC-A) and B (NPR-B/GC-B) are members of the transmembrane guanylyl cyclase family that mediate the effects of natriuretic peptides via the second messenger, cGMP. Despite numerous reports of these receptors being down-regulated in response to various pathological conditions, no studies have actually measured desensitization and receptor internalization in t...
The present study was designed to examine the short-term and long-term effects of increased plasma levels of atrial natriuretic peptide on the glomerular filtration rate, sodium excretion, and arterial pressure. Intravenous infusion of synthetic atrial natriuretic peptide (2 micrograms/kg/bolus, 50 ng/kg/min continuous infusion) for 45 minutes in six conscious dogs increased plasma levels of im...
Natriuretic peptides have emerged as important candidates for development of diagnostic tools and therapeutic agents in cardiovascular disease. The family contains of three major peptides-ANP, BNP, CNP-that participate in cardiovascular and cardiorenal homeostasis. Each of these natriuretic peptides binds differentially to specific receptors that signal through different mechanisms. They are cl...
