Dynorphin Controls the Gain of an Amygdalar Anxiety Circuit

open access: yesCell Reports, 2016
Kappa opioid receptors (KORs) are involved in a variety of aversive behavioral states, including anxiety. To date, a circuit-based mechanism for KOR-driven anxiety has not been described.

Modulatory effects of orexin and dynorphin on stress-related alcohol seeking and relapse: pivotal role of the posterior paraventricular nucleus of the thalamus [PDF]

open access: yesFrontiers in Pharmacology
Alcohol use disorder (AUD) remains a significant problem in the United States, resulting in over 178,000 alcohol-related deaths annually. A central problem in treating AUD is the high rate of relapse to alcohol use even after protracted periods of ...

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

open access: yesNeuropsychopharmacology Reports
Aim We aimed to create a rat model of drug‐induced parkinsonism and tardive dyskinesia by chronic administration of haloperidol and examine the expression of direct and indirect pathway markers in the striatum of the model rats.

Dysregulated Plasticity in Serotonin, Galanin, and Opioid Systems Contributes to Limbic Seizure Recruitment in Wistar Audiogenic Rat. [PDF]

open access: yesJ Neurochem
To find molecular reasons why a genetic rat model (Wistar Audiogenic Rat, WAR) moves from sound‐triggered brainstem seizures to longer‐lasting limbic (temporal‐lobe) epilepsy after repeated loud‐noise exposure. WAR and normal Wistar rats received a 10‐day audiogenic kindling (twice‐daily loud noise).

Optogenetic stimulation of lateral hypothalamic orexin/dynorphin inputs in the ventral tegmental area potentiates mesolimbic dopamine neurotransmission and promotes reward-seeking behaviours

open access: yesNeuropsychopharmacology, 2021
Reward and reinforcement processes are critical for survival and propagation of genes. While numerous brain systems underlie these processes, a cardinal role is ascribed to mesolimbic dopamine.

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.

SEQUENCE ANALYSIS SUGGESTS POSITIVE SELECTION ON THE BOVINE PRODYNORPHIN GENE [PDF]

open access: yesBAG. Journal of Basic and Applied Genetics, 2020
Dynorphin A is an endogenous opioid peptide that is part of the KNDy system in the hypothalamus of mammals. This peptide acts as an inhibitor of the GnRH pulse generation, thus regulating the onset of puberty and reproductive cycles.
