Modelling KNDy neurons and gonadotropin-releasing hormone pulse generation. [PDF]

open access: yesCurr Opin Endocr Metab Res, 2022
The pulsatile release of gonadotropin-releasing hormone (GnRH) and its frequency are crucial for healthy reproductive function. To understand what drives GnRH pulses a combination of experimental and mathematical modelling approaches have been used ...

KNDy Neurons as the GnRH Pulse Generator: Recent Studies in Ruminants [PDF]

open access: yesPeptides, 2023
This review considers three aspects of recent work on the role of KNDy neurons in GnRH pulse generation in ruminants. First, work on basic mechanisms of pulse generation includes several tests of this hypothesis, all of which support it, and evidence that Kiss1r-containing neurons form a positive feedback circuit with the KNDy neural network that ...

Hierarchical Deployment of Tbx3 Dictates the Identity of Hypothalamic KNDy Neurons to Control Puberty Onset [PDF]

open access: yesScience Advances, 2022
The neuroendocrine system consists of a heterogeneous collection of neuropeptidergic neurons in the brain, among which hypothalamic KNDy neurons represent an indispensable cell subtype controlling puberty onset. Although neural progenitors and neuronal precursors along the cell lineage hierarchy adopt a cascade diversification strategy to generate ...

KNDy Neurons and the Control of the Gonadotropic Axis in the Midgestation Fetal Sheep.

open access: yesEndocrinology
KNDy neurons, located in the hypothalamic arcuate nucleus, coexpress kisspeptin (Kiss), neurokinin B, and dynorphin and play a crucial role in regulating GnRH/LH secretion in midgestation sheep fetuses.

Mapping of KNDy Neurons and Immunohistochemical Analysis of the Interaction Between KNDy and Substance P Neural Systems in Goat [PDF]

open access: yesJournal of Reproduction and Development, 2017
A population of neurons in the arcuate nucleus (ARC) coexpresses kisspeptin, neurokinin B (NKB), and dynorphin, and therefore they are referred to as KNDy neurons. It has been suggested that KNDy neurons participate in several brain functions, including the control of reproduction.

Prenatal Androgen Exposure Alters KNDy Neurons and Their Afferent Network in a Model of Polycystic Ovarian Syndrome.

open access: yesEndocrinology, 2021
Abstract Polycystic ovarian syndrome (PCOS), the most common endocrinopathy affecting women worldwide, is characterized by elevated luteinizing hormone (LH) pulse frequency due to the impaired suppression of gonadotrophin-releasing hormone (GnRH) release by steroid hormone negative feedback.

Highly redundant neuropeptide volume co-transmission underlying episodic activation of the GnRH neuron dendron [PDF]

open access: yeseLife, 2021
The necessity and functional significance of neurotransmitter co-transmission remains unclear. The glutamatergic ‘KNDy’ neurons co-express kisspeptin, neurokinin B (NKB), and dynorphin and exhibit a highly stereotyped synchronized behavior that reads out

Deletion of Growth Hormone Secretagogue Receptor in Kisspeptin Neurons in Female Mice Blocks Diet-Induced Obesity

open access: yesBiomolecules, 2022
The gut peptide, ghrelin, mediates energy homeostasis and reproduction by acting through its receptor, growth hormone secretagogue receptor (GHSR), expressed in hypothalamic neurons in the arcuate (ARC).

Conditional Oprk1-dependent Kiss1 deletion in kisspeptin neurons caused estrogen-dependent LH pulse disruption and LH surge attenuation in female rats

open access: yesScientific Reports, 2023
The gonadotropin-releasing hormone (GnRH) pulse and surge are considered to be generated by arcuate kisspeptin/neurokinin B/dynorphin A (KNDy) neurons and anteroventral periventricular nucleus (AVPV) kisspeptin neurons, respectively, in female rodents ...
