GnRH pulse generator activity in mouse models of polycystic ovary syndrome [PDF]

open access: yeseLife
One in ten women in their reproductive age suffer from polycystic ovary syndrome (PCOS) that, alongside subfertility and hyperandrogenism, typically presents with increased luteinizing hormone (LH) pulsatility.

Brainstem noradrenergic modulation of the kisspeptin neuron GnRH pulse generator in mice [PDF]

open access: yesNature Communications
Brainstem noradrenaline (NA) neurons modulate the activity of many neural networks including those responsible for the control of fertility. Using brain slice electrophysiology, we demonstrate that the arcuate nucleus kisspeptin (ARNKISS) neurons ...

Continuous acceleration of neural activity of the GnRH pulse generator during chronic peripheral infusion of neurokinin 3 receptor agonist in goats [PDF]

open access: yesThe Journal of Reproduction and Development, 2023
Secretion of pulsatile gonadotropin-releasing hormone (GnRH) is essential for reproduction. Kisspeptin neurons in the arcuate nucleus (ARC), which coexpress neurokinin B (NKB) and its receptor (NK3R), are believed to be components of the GnRH pulse ...

Definition of the estrogen negative feedback pathway controlling the GnRH pulse generator in female mice [PDF]

open access: yesNature Communications, 2022
Estrogen secreted by the ovary controls how the brain drives pulsatile reproductive hormone secretion. The authors show that in mice, estrogen receptor alpha within a specific population of hypothalamic kisspeptin neurons is the principal pathway through

Local administration of Neurokinin B in the arcuate nucleus accelerates the neural activity of the GnRH pulse generator in goats [PDF]

open access: yesThe Journal of Reproduction and Development, 2021
Kisspeptin neurons in the arcuate nucleus (ARC), which co-express neurokinin B (NKB) and dynorphin A, are termed KNDy neurons. These neurons are candidates for the intrinsic gonadotropin-releasing hormone (GnRH) pulse generator.

Neuroendocrine mechanisms leading to novel control techniques of reproduction in livestock: Regulation of the GnRH pulse generator activity [PDF]

open access: yesThe Journal of Reproduction and Development
Pulsatile secretion of gonadotropin-releasing hormone (GnRH) is essential for normal reproductive function in mammals. GnRH pulses from the hypothalamus drive pulsatile gonadotropin release from the anterior pituitary, thereby

Role of KNDy Neurons Expressing Kisspeptin, Neurokinin B, and Dynorphin A as a GnRH Pulse Generator Controlling Mammalian Reproduction [PDF]

open access: yesFrontiers in Endocrinology, 2021
Increasing evidence accumulated during the past two decades has demonstrated that the then-novel kisspeptin, which was discovered in 2001, the known neuropeptides neurokinin B and dynorphin A, which were discovered in 1983 and 1979, respectively, and ...

Examining a central mechanism whereby undernutrition inhibits GnRH secretion via KNDy neurons [PDF]

open access: yesThe Journal of Reproduction and Development
The negative impact of undernutrition on reproduction is evident in animal agriculture and human health, but our understanding of the central mechanism that links energy balance and reproduction is far from complete.

Involvement of cocaine- and amphetamine-regulated transcript neurons in glucoprivic suppression of pulsatile luteinizing hormone secretion in female rats [PDF]

open access: yesThe Journal of Reproduction and Development
Malnutrition often suppresses reproductive function by inhibiting the pulsatile secretion of gonadotropin-releasing hormone (GnRH)/gonadotropins in mammals.

The role of amygdala GABA neurons in controlling stress and reproduction in female mice [PDF]

open access: yesNature Communications
Stress can disrupt menstrual cycles, impair fertility and cause reproductive disfunction. The posterodorsal medial amygdala (MePD) integrates stress signals and regulates the gonadotropin-releasing hormone (GnRH) pulse generator through a dense network ...
