Background Prostaglandin E2 (PGE2) binds to four receptor subtypes (EP1, EP2, EP3 and EP4) and plays an important role in response to stress. However, the identity of the receptor(s) responsible for PGE2 regulation of neuronal activity and signaling

Several members of the RFamide peptide family are known to have role in the regulation of feeding. For example, neuropeptide FF and prolactin-releasing peptide cause anorexigenic, while 26RFa and QRFP result in orexigenic effects in rodents. I.c.v. m

Some members of the RFamide peptide family are associated with feeding in rodents. For example, neuropeptide FF and prolactin-releasing peptide cause anorexigenic, while 26RFa and QRFP result in orexigenic effects. I.c.v. microinjection of RFamide-re

In the present study the role of brain AT(2) receptor in the cardiovascular response to stress was investigated in conscious rats. Footshock-stress increased mean arterial pressure (MAP) and heart rate (p0.0001). Intracerebroventricular (i.c.v.) admi

Interoreceptors in the central nervous system elicit compensatory behavioral and physiological responses to cellular glucopenia. Antagonism of mu and kappa opioid receptors attenuates glucoprivic hyperphagia, findings that implicate these peptidergic

Intracerebroventricular administration of the angiotensin AT-2 receptor antagonist, PD 123319, inhibited drinking induced in rats by hypertonic NaCl, carbachol, isoproterenol, hypovolemia, and water deprivation, but had no effect on food intake. In c

To assess the possible involvement of NMDA receptors in mediating the expression of striatal c-fos by cocaine injection, we investigated the effects of the noncompetitive NMDA receptor antagonists, ketamine and (+)-5-methyl-10,11-dihydro-5H-dibenzo[a

The present experiments examined the effect of ketanserin [5-hydroxytryptamine-2 (5-HT2) antagonist] and 8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) (5-HT1 agonist) on the in vitro release of luteinizing-hormone-releasing hormone (LHRH) from

Manipulating neuronal histamine in the hypothalamus, its effects on brain functions were assessed in nonobese normal rats and Zucker rats. Alpha-fluoromethylhistidine (FMH), an inhibitor of histamine synthesis, induced feeding dose-dependently after

During early postnatal development rat pups were treated twice daily with the beta-adrenergic antagonist propranolol (15 mg/kg) in order to study the acute and long-lasting effects of early blockade of noradrenergic beta-mediated neurotransmission. T
