Gonadotropin-releasing hormone (GnRH) is present within neurons of the nervus terminalis, the zeroeth cranial nerve. In all vertebrate species, except in sharks where it is a separate nerve, the nervus terminalis consists of a chain of neurons embedded within olfactory or vomeronasal nerves in the nasal cavity. The function of the GnRH component of the nervus terminalis is thought to be neuromo...
The neuropeptides gonadotropin-releasing hormone (GnRH) and kisspeptin (KiSS), and their receptors gonadotropin-releasing hormone receptor (GnRHR) and kisspeptin receptor (KiSSR) play key roles in vertebrate reproduction. Multiple paralogous isoforms of these genes have been identified in various vertebrate species. Two rounds of genome duplication in early vertebrates likely contributed to the...
Biological activity of a synthetic peptide with inhibin-like activity under in vitro and in vivo conditions was compared with three highly potent synthetic lutropin-releasing hormone antagonists. Unlike the synthetic lutropin-releasing hormone antagonists, which effectively inhibited both lutropin and follitropin secretion from the pituitary, the inhibin-like peptide showed a preferential effec...
Physical and psychological stressors suppress hypothalamic-pituitary-gonadal axis activity and sexual behavior and consequently induce reproductive dysfunction. Recently, it has been shown that gonadotropin-inhibitory hormone (GnIH), also called RFamide-related peptide 3 (RFRP) in mammals, which is a potent inhibitory regulator of gonadotropin-releasing hormone (GnRH) and gonadotropin, is invol...
