Stress-Induced Reinstatement of Drug Seeking: 20 Years of Progress [PDF]

open access: yes, 2015
In human addicts, drug relapse and craving are often provoked by stress. Since 1995, this clinical scenario has been studied using a rat model of stress-induced reinstatement of drug seeking.

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 ...

Rapid-Onset Anti-Stress Effects of a Kappa-Opioid Receptor Antagonist, LY2795050, Against Immobility in an Open Space Swim Paradigm in Male and Female Mice

open access: yesFrontiers in Pharmacology, 2021
The kappa-opioid receptor (KOR) / dynorphin system is implicated with behavioral and neurobiological effects of stress exposure (including heavy exposure to drugs of abuse) in translational animal models.

Estradiol treatment prevents injury induced enhancement in spinal cord dynorphin expression.

open access: yesFrontiers in Physiology, 2012
Administration of the ovarian steroid estradiol in male and female animals has been shown to have neuromodulatory and neuroprotective effects in a variety of experimental models. In the present study, spinal tissues from dermatomes just above (T5-7, at

Dynorphin and the pathophysiology of drug addiction [PDF]

open access: yesPharmacology & Therapeutics, 2007
Drug addiction is a chronic relapsing disease in which drug administration becomes the primary stimulus that drives behavior regardless of the adverse consequence that may ensue. As drug use becomes more compulsive, motivation for natural rewards that normally drive behavior decreases. The discontinuation of drug use is associated with somatic signs of

Alterations in Cortical and Basal Ganglia Levels of Opioid Receptor Binding in a Rat Model of l-DOPA-Induced Dyskinesia

open access: yesNeurobiology of Disease, 2001
Opioid receptor-binding autoradiography was used as a way to map sites of altered opioid transmission in a rat model of l-DOPA-induced dyskinesia. Rats with unilateral 6-hydroxydopamine lesions of the nigrostriatal pathways sustained a 3-week treatment ...

Acute Wheel-Running Increases Markers of Stress and Aversion-Related Signaling in the Basolateral Amygdala of Male Rats

open access: yesJournal of Functional Morphology and Kinesiology, 2022
Physical activity (PA) is a non-invasive, cost-effective means of reducing chronic disease. Most US citizens fail to meet PA guidelines, and individuals experiencing chronic stress are less likely to be physically active.

Actions of D-Ala2-D-Leu5-enkephalin and dynorphin A (1–17) on neocortical neurons in vitro [PDF]

open access: yes, 1984
Intracellular recordings were made from neocortical neurons in vitro. Application of D-Ala2-D-Leu5-enkephalin (DADL) by different methods produced a decrease in EPSP amplitude and in the amplitude of L-glutamate-induced depolarizations without changes in

High-frequency stimulation-induced peptide release synchronizes arcuate kisspeptin neurons and excites GnRH neurons

open access: yeseLife, 2016
Kisspeptin (Kiss1) and neurokinin B (NKB) neurocircuits are essential for pubertal development and fertility. Kisspeptin neurons in the hypothalamic arcuate nucleus (Kiss1ARH) co-express Kiss1, NKB, dynorphin and glutamate and are postulated to provide ...

Functional Characterization of Spinocerebellar Ataxia Associated Dynorphin A Mutant Peptides

open access: yesBiomedicines, 2021
Mutations in the prodynorphin gene (PDYN) are associated with the development of spinocerebellar ataxia type 23 (SCA23). Pathogenic missense mutations are localized predominantly in the PDYN region coding for the dynorphin A (DynA) neuropeptide and lead ...
