Effect of neurokinin B and dynorphin A on kisspeptin-10 secretion from the anterior pituitary cells of pubescent ewes in vitro [PDF]
Journal of Veterinary ResearchNeurokinin B (NKB), dynorphin A (Dyn A) and kisspeptin (KiSS) are key agents that participate in the neuroendocrine regulation of the development and functioning of the reproductive system.

Influence of neurokinin B, dynorphin A and kisspeptin-10 on in vitro gonadotropin secretion by anterior pituitary cells isolated from pubescent ewes [PDF]
Journal of Veterinary ResearchThe hypothalamic neuropeptides kisspeptin-10 (KiSS-10), neurokinin B (NKB), and dynorphin A (Dyn A) play roles in the endocrine regulation of the hypothalamic–pituitary–ovarian (HPO) axis in puberty.

Functional Characterization of Spinocerebellar Ataxia Associated Dynorphin A Mutant Peptides [PDF]
Biomedicines, 2021 Mutations in the prodynorphin gene (PDYN) are associated with the development of spinocerebellar ataxia type 23 (SCA23). Pathogenic missense mutations are localized predominantly in the PDYN region coding for the dynorphin A (DynA) neuropeptide and lead ...

A midbrain dynorphin circuit promotes threat generalization [PDF]
Current Biology, 2021 Discrimination between predictive and non-predictive threat stimuli decreases as threat intensity increases. The central mechanisms that mediate the transition from discriminatory to generalized threat responding remain poorly resolved. Here, we identify the stress- and dysphoria-associated kappa opioid receptor (KOR) and its ligand dynorphin (Dyn ...
