Dynorphin Controls the Gain of an Amygdalar Anxiety Circuit
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]
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]
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]
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).

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