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 Research
The 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.

Compartment-specific opioid receptor signaling is selectively modulated by different dynorphin peptides

eLife, 2021
Many signal transduction systems have an apparent redundancy built into them, where multiple physiological agonists activate the same receptors. Whether this is true redundancy, or whether this provides an as-yet unrecognized specificity in downstream ...

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

Frontiers 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 ...

The dynorphin/kappa opioid receptor mediates adverse immunological and behavioral outcomes induced by repetitive blast trauma [PDF]

Journal of Neuroinflammation, 2022
Background Adverse pathophysiological and behavioral outcomes related to mild traumatic brain injury (mTBI), posttraumatic stress disorder (PTSD), and chronic pain are common following blast exposure and contribute to decreased quality of life, but ...

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 Research
Neurokinin 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.

Enhanced dynorphin expression and secretion in pancreatic beta-cells under hyperglycemic conditions [PDF]

Molecular Metabolism
Objective: Dynorphin, an endogenous opioid peptide predominantly expressed in the central nervous system and involved in stress response, pain, and addiction, has intrigued researchers due to its expression in pancreatic β-cells.

Isotalatizidine, a C19-diterpenoid alkaloid, attenuates chronic neuropathic pain through stimulating ERK/CREB signaling pathway-mediated microglial dynorphin A expression

Journal of Neuroinflammation, 2020
Background Isotalatizidine is a representative C19-diterpenoid alkaloid extracted from the lateral roots of Aconitum carmichaelii, which has been widely used to treat various diseases on account of its analgesic, anti-inflammatory, anti-rheumatic, and ...

CRF1-R activation of the dynorphin/kappa opioid system in the mouse basolateral amygdala mediates anxiety-like behavior.

PLoS ONE, 2009
Stress is a complex human experience and having both rewarding and aversive motivational properties. The adverse effects of stress are well documented, yet many of underlying mechanisms remain unclear and controversial. Here we report that the anxiogenic
