Does Intracerebroventricularly-Injected Exendin-(9-39) Prevent the Cardiovascular Effects of Central Glucagon-Like Peptide-1?
Abstract
In this study, we aimed to investigate the effects of intracerebroventricularly (i.c.v.)-injected glucagon-like peptide-1 (GLP-1) on blood pressures and heart rates of conscious, freely-moving rats, and whether specific receptors mediate these effects. Male Wistar albino rats used throughout the experiments were implanted with a cathether through the right femoral artery and with a cannula into the right lateral ventricle for i.c.v. injections, under ether anesthesia. Blood pressure and heart rate were recorded by a “TDA96 Transducer Data Acquisition System”. Blood pressures and heart rates of rats were observed before and for 30 minutes following drug injections. I.c.v. GLP-1 (100, 500 and 1000 ng/10 μl) caused a dose-dependent increase in both blood pressure and heart rate. The effects of GLP-1 on blood pressure and heart rate were inhibited by i.c.v. receptor antagonist exendin-(9-39) (2500 ng/μl). Our data indicate that i.c.v. GLP-1 increases blood pressure and heart rate, and that activation of central specific receptors mediate these effects.
