Pulsatile administration of gonadotropin-releasing hormone agonist to gilts actively immunized against gonadotropin-releasing hormone.
Sexually mature gilts (n = 20) were actively immunized against GnRH. Primary and booster immunizations of GnRH conjugated to bovine serum albumin induced production of antibodies in all gilts. Nineteen of the gilts became acyclic with suppressed concentrations of gonadotropins and estradiol. Intravenous challenges with 100 micrograms GnRH and 5 micrograms D-(Ala6, des-Gly-NH2(10)) ethylamide Gn...
متن کاملFunction of gonadotropin-releasing hormone in olfaction.
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...
متن کاملMathematical modeling of gonadotropin-releasing hormone signaling
Gonadotropin-releasing hormone (GnRH) acts via G-protein coupled receptors on pituitary gonadotropes to control reproduction. These are Gq-coupled receptors that mediate acute effects of GnRH on the exocytotic secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as the chronic regulation of their synthesis. GnRH is secreted in short pulses and GnRH effects on it...
متن کاملMultitasking in Gonadotropin-Releasing Hormone Neuron Dendrites.
Gonadotropin-releasing hormone (GnRH) neurons integrate synaptic information in their dendrites in order to precisely control GnRH secretion and hence fertility. Recent discoveries concerning the structure and function of GnRH neuron dendrites have shed new light on the control of GnRH neuron excitability and GnRH secretion. This work suggests that GnRH neurons have a unique projection to the m...
متن کاملNeuromodulation of Transplanted Gonadotropin-Releasing Hormone Neurons
Implantation of normal preoptic area (POA) tissue into the third ventricle of adult hypogonadal (HPG) mice provides a source of GnRH neurons that innervate the host median eminence and stimulate reproductive development in the sterile mutants. To further evaluate graft-host integration, the effects of N-methyl-D,L-aspartic acid (NMA) and opiate antagonists on LH secretion in HPG mice with POA t...
