Electrophysiological analysis of the inhibitory effects of FMRFamide - like peptides on 3 the pacemaker activity of gonadotropin - releasing hormone neurons
33 Gonadotropin-releasing hormone (GnRH) neurons in the terminal nerve (TN) show 34 endogenous pacemaker activity, which is suggested to be dependent on the 35 physiological conditions of the animal. The TN-GnRH neurons have been suggested to 36 function as a neuromodulatory neuron that regulates long-lasting changes in the animal 37 behavior. It has been reported that the TN-GnRH neurons are i...

متن کاملCoexpression of gonadotropin inhibitory hormone with Agouti-related peptide in the neurons of arcuate nucleus of ewe hypothalamus
Introduction: Gonadotropin inhibitory hormone (GnIH) and Agouti-related peptide (AgRP) are orexigenic peptides expressed in the arcuate nucleus (Arc) of the hypothalamus in the ewe. In addition, effects of GnIH and AgRP on the regulation of gonadotropin releasing hormone secretion have been shown in some mammals. The objective of the present study was to investigate the coexpression of GnIH ...
متن کاملInteractions of gonadotropin-releasing hormone (GnRH) and gonadotropin-inhibitory hormone (GnIH) in birds and mammals.
Gonadotropin-releasing hormone (GnRH) regulates secretion of both of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone. Thus, it is a key hormone for vertebrate reproduction. GnRH was considered to be unusual among hypothalamic neuropeptides in that it appeared to have no direct antagonist, although some neurochemicals and peripheral hormones (opiates, GABA, gonadal s...
متن کاملThe FMRFamide-Like Peptide Family in Nematodes
In the three decades since the FMRFamide peptide was isolated from the mollusk Macrocallista nimbosa, structurally similar peptides sharing a C-terminal RFamide motif have been identified across the animal kingdom. FMRFamide-like peptides (FLPs) represent the largest known family of neuropeptides in invertebrates. In the phylum Nematoda, at least 32 flp-genes are classified, making the FLP syst...
