Time of Day Influences on Gonadotropin Releasing Hormone Neurons
Gonadotropin Releasing Hormone (GnRH) neurons are typically referred to as the final component of the neuronal network that regulated reproduction. Though it has been known since the 1920's that the decapeptide released by these neuroendocrine cells is the fundamental driver of ovulation in …

Autocrine regulation of gonadotropin-releasing hormone in immortalized hypothalamic GT1-7 neurons
… of an ultrashort feedback mechanism regulating GnRH secretion has been supported from in vivo and in vitro studies. However, the complex synaptic connections of GnRH neurons with other neural elements made it difficult to determine whether the regulation was mediated by direct actions on the …

A Mathematical Model for the Transition in Firing Patterns Across Puberty of a Gonadotropin-Releasing Hormone Neuron
… is that, the activity of a certain network of neurons called Gonadotropin-Releasing Hormone (GnRH) neurons lies at the very heart of this puzzle. For my thesis, I develop and analyze a deterministic mathematical model of a GnRH neuron consisting of a system of differential equations based on …

Disrupted female reproductive cyclicity and gonadotropin-releasing hormone neuron dysfunction in a mouse model of temporal lobe epilepsy
… Hypothalamic gonadotropin-releasing hormone (GnRH) neurons are key players in the neural control of reproduction through the hypothalamic-pituitary-gonadal (HPG) axis. At two months post-injection, the effects of epilepsy on the GnRH neuron function are dynamic across the estrous cycle, …

The Role of Neurokinin B in the Regulation of the Preovulatory LH Surge in Ewes
… function. Gonadotropin-releasing hormone (GnRH) is secreted by hypothalamic GnRH neurons into the hypophysial portal circulation. When GnRH reaches the anterior pituitary, it stimulates gonadotropes to secrete luteinizing hormone (LH) into the systemic circulation, ultimately leading to …

Intrinsic Neuronal Plasticity of Kiss1 Neurons in Mice around Puberty
… in mammals. Gonadotropin-releasing hormone (GnRH) is released from the hypothalamus by GnRH neurons, stimulating the anterior pituitary to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones act on the gonads to promote gametogenesis and the production of …

The gonadotropin-releasing hormone (GnRH) system: a comparison between breeding and non-breeding naked mole rats (Heterocephalus glaber)
… pituitary gland. Gonadotropin-releasing hormone (GnRH) is a neuropeptide typically produced in the hypothalamus. It is the key neuropeptide for initiating this cascade, and without it, reproduction cannot occur. Naked mole rats (Heterocephalus glaber) have a rigid social hierarchy. The "queen" is …

NOVEL INSIGHTS INTO GENETIC AND ENVIRONMENTAL DETERMINANTS SHAPING GNRH NEURON BIOLOGY AND RELATED REPRODUCTIVE DISORDERS
… the secretion of gonadotropin-releasing hormone (GnRH), a neuropeptide that stimulates the release of gonadotropins from the pituitary, driving gametogenesis and sex steroid production. GnRH-secreting neurons originate from the olfactory placode during embryogenesis and migrate into the forebrain …

Cloning and characterisation of gonadotropin-releasing hormone (GnRH) receptors in the cichlid (Haplochromis burtoni) and the zebrafish (Danio rerio)
… forms of gonadotropin-releasing hormone (GnRH) in a single species is becoming a common occurrence. The highly conserved chicken GnRH II is present along with one or two other GnRHs, composing a combination unique to particular species. This multifunctional peptide is widely distributed …
