Ginsenoside Re protects methamphetamine-induced dopaminergic neurotoxicity in mice via upregulation of dynorphin-mediated κ-opioid receptor and downregulation of substance P-mediated neurokinin 1 receptor [PDF]

open access: yesJournal of Neuroinflammation, 2018
Background We previously reported that ginsenoside Re (GRe) attenuated against methamphetamine (MA)-induced neurotoxicity via anti-inflammatory and antioxidant potentials.

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

open access: yeseLife, 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

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.

Dynorphin activation of kappa opioid receptor promotes microglial polarization toward M2 phenotype via TLR4/NF-κB pathway

open access: yesCell & 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 ...

Label-free, real-time monitoring of membrane binding events at zeptomolar concentrations using frequency-locked optical microresonators [PDF]

open access: yesNature Communications
G-protein coupled receptors help regulate cellular function and communication, and are targets of small molecule drug discovery efforts. Conventional techniques to probe these interactions require labels and large amounts of receptor to achieve ...

Distribution and regulation of gonadotropin-releasing hormone, kisspeptin, RF-amide related peptide-3, and dynorphin in the bovine hypothalamus [PDF]

open access: yesPeerJ, 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 ...

Co‐Expression of Tardive Dyskinesia and Drug‐Induced Parkinsonism in Rats Chronically Treated With Haloperidol [PDF]

open access: yesNeuropsychopharmacol Rep
Rats chronically treated with haloperidol exhibit drug‐induced parkinsonism and tardive dyskinesia. Expression of dynorphin, enkephalin, and dopamine D1 and D2 receptors was altered in haloperidol‐treated rats. Both indirect and direct pathways are involved in haloperidol‐induced movement disorders.

Ester hydrolysis differentially reduces aconitine-induced anti-hypersensitivity and acute neurotoxicity: Involvement of spinal microglial dynorphin expression and implications for Aconitum processing

open access: yesFrontiers in Pharmacology, 2016
Aconitines, including bulleyaconitine A, probably the most bioactive and abundant alkaloids in Aconitum plant, are a group of diester C19-diterpenoid alkaloids with one acetylester group attached to C8 of the diterpenoid skeleton and one benzoylester ...
