Membrane Leakage Induced by Dynorphins
FEBS Letters, 2006 Dynorphins, endogeneous opioid peptides, function as ligands to the opioid kappa receptors and induce non‐opioid excitotoxic effects. Here we show that big dynorphin and dynorphin A, but not dynorphin B, cause leakage effects in large unilamellar phospholipid vesicles (LUVs).

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 ...

Kisspeptin, Neurokinin B, and Dynorphin Expression during Pubertal Development in Female Sheep
Biology, 2021 The neural mechanisms underlying increases in gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) secretion that drive puberty onset are unknown.

Cell & Bioscience, 2020 Background Microglia-mediated neuroinflammation is associated with epilepsy. Switching microglial polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype represents a novel therapeutic strategy for mitigating ...

Distribution and regulation of gonadotropin-releasing hormone, kisspeptin, RF-amide related peptide-3, and dynorphin in the bovine hypothalamus [PDF]
PeerJ, 2016 Recent work has led to the hypothesis that kisspeptin/neurokinin B/dynorphin (KNDy) neurons in the arcuate nucleus (ARC) play a key role in gonadotropin-releasing hormone (GnRH) pulse generation and gonadal steroid feedback, with kisspeptin driving GnRH ...

Dynorphin, stress, and depression [PDF]
Brain Research, 2010 Stress is most often associated with aversive states. It rapidly induces the release of hormones and neuropeptides including dynorphin, which activates kappa opioid receptors (KORs) in the central and peripheral nervous systems. In animal models, many aversive effects of stress are mimicked or exacerbated by stimulation of KORs in limbic brain regions.

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

Neurobiology of Disease, 2006 Up to 89% of patients with herpes simplex virus type-1 (HSV-1) encephalitis can have seizures. Possibly, viruses are environmental triggers for seizures in genetically vulnerable individuals. Inherited dynorphin promoter polymorphisms are associated with

Frontiers in Pharmacology, 2021 Bulleyaconitine A (BAA), a C19-diterpenoid alkaloid, has been prescribed as a nonnarcotic analgesic to treat chronic pain over four decades in China. The present study investigated its inhibition in morphine-induced withdrawal symptoms, conditioned place

The Journal of Reproduction and Development, 2019 Increasing evidence shows that puberty onset is largely dependent on body weight rather than chronological age. To investigate the mechanism involved in the energetic control of puberty onset, the present study examined effects of chronic food ...
