A role for glial fibrillary acidic protein (GFAP)-expressing cells in the regulation of gonadotropin-releasing hormone (GnRH) but not arcuate kisspeptin neuron output in male mice

open access: yeseLife, 2021
GnRH neurons are the final central neural output regulating fertility. Kisspeptin neurons in the hypothalamic arcuate nucleus (KNDy neurons) are considered the main regulator of GnRH output.

Modulation of pulsatile GnRH dynamics across the ovarian cycle via changes in the network excitability and basal activity of the arcuate kisspeptin network

open access: yeseLife, 2021
Pulsatile GnRH release is essential for normal reproductive function. Kisspeptin secreting neurons found in the arcuate nucleus, known as KNDy neurons for co-expressing neurokinin B, and dynorphin, drive pulsatile GnRH release.

Research progress of the role of Kisspeptin in puberty onset [PDF]

open access: yesJichu yixue yu linchuang, 2022
Kisspeptin activates the hypothalamic-pituitary-gonadal axis (HPGA) and regulates the pulsatile secretion of gonadotropin-releasing hormone (GnRH) through KNDy neurons, thereby regulating the initiation of the pubertal phase.

Divergent effects of hyperandrogenemia on the female reproductive neuroendocrine axis under different physiological conditions. [PDF]

open access: yesJ Neuroendocrinol
Abstract The hypothalamic–pituitary–gonadal (HPG) axis coordinates reproductive function and incorporates gonadal sex steroid feedback to regulate gonadotropin secretion in a homeostatic manner. In females, ovarian estrogens and progestins act as the primary negative feedback signals to suppress luteinizing hormone (LH) release, whereas in males ...

Kisspeptin, Neurokinin B, and Dynorphin Expression during Pubertal Development in Female Sheep

open access: yesBiology, 2021
The neural mechanisms underlying increases in gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) secretion that drive puberty onset are unknown.

Opioidergic pathways and kisspeptin in the regulation of female reproduction in mammals

open access: yesFrontiers in Neuroscience, 2022
Endogenous opioid peptides have attracted attention as critical neuropeptides in the central mechanism regulating female reproduction ever since the discovery that arcuate dynorphin neurons that coexpress kisspeptin and neurokinin B (NKB), which are also

Synergistic Control of KNDy Neuronal Influence on Energy Balance by Ghrelin and Estradiol [PDF]

open access: yesJournal of the Endocrine Society, 2021
Abstract The gut peptide, ghrelin, mediates negative energy homeostasis and the neuroendocrine control of energy homeostasis by acting through its receptor, growth hormone secretagogue receptor (GHSR). GHSR, expressed in hypothalamic Kisspeptin/Neurokinin B/Dynorphin (KNDy) neurons in the arcuate (ARC), is well known to regulate energy ...

The Role of KNDy Neurons in Estrogen Modulation of LH Release, Body Weight, and Thermoregulation

open access: yes, 2012
Up to 80% of menopausal women suffer from hot flushes, consisting of a coordinated activation of heat loss mechanisms (sweating, cutaneous vasodilatation, etc.).

KNDy neurone activation prior to the LH surge of the ewe is disrupted by LPS [PDF]

open access: yesReproduction, 2017
Abstract In the ewe, steroid hormones act on the hypothalamic arcuate nucleus (ARC) to initiate the GnRH/LH surge. Within the ARC, steroid signal transduction may be mediated by estrogen receptive dopamine-, β-endorphin- or neuropeptide Y (NPY)-expressing cells, as well as those co-localising kisspeptin, neurokinin B (NKB) and ...
