Dynorphins are opioid peptides that derive from the prodynorphin precursor and are the presumed endogenous ligands for the [kappa] opioid receptor (Chavkin et al., 1982). Treatment of alcohol dependence with drug antagonists of the stress response The topics include neuropeptide biosynthesis, dynorphi...

Both phenomena often are induced or exacerbated by physical or psychological stress. Biological systems known to regulate the body's overall response to stress use and release endogenous neuroactive opioid peptides. These stress-related neuromodulators consist of products derived from three genetically ...
by acting on their corresponding opioid receptors, are responsible for numbing pain, creating feelings of euphoria and increasing energy. They also play a role in the normal functioning of the gastrointestinal and immune systems, as well as modulate how the body deals with stress. ...
Enkephalin and dynorphin mRNA expression are associated with resilience or vulnerability to chronic social defeat stress There are important and enduring differences between individuals in the magnitude of all aspects of the stress response. Among the neuropeptide systems, th... Patrick Bérubé a,Sylvie...
Garvan Institute of Medical Research, Darlinghurst, NSW, Australia Stress and anxiety are mainly regulated by amygdala and hypothalamic circuitries involving several neurotransmitter systems and providing physiological responses to peripheral organs via the hypothalamic–pituitary–adrenal axis and other pathways...
Aim: To investigate the changes of enkaphalin mRNA andprodynorphinmRNA gene expression in rat brain regions with chro-(nic) immobilization stress and the influence of Chinese herbs. 目的:研究慢性束缚应激时大鼠海马脑啡肽和前强啡肽mRNA基因表达的变化以及逍遥散、四君子汤、金匮肾气丸三种中药复方对其的...
Previous studies have shown that processed Fuzi, obtained after autoclaving crude Aconiti tuber (Ranunculaceae Aconitum carmichaeli Debeaux; Iwate, Japan) to minimize its toxicity, are efficient in relieving pain in repeated cold stress mice, chronic constriction injury (CCI) neuropathic pain as well ...
Activation of 魏-opioid receptors by dynorphins has been associated with stress-related memory impairments. Interestingly, these peptides can also modulate glutamate neurotransmission and may affect synaptic plasticity underlying memory formation. N-methyl-D-aspartate (NMDA) and 伪-amino-3-hydroxy-5-...
Brain adrenocorticotrophic hormone (ACTH) and 尾-endorphin levels were significantly and negatively correlated with the number of rattlings, which is consistent with the hypothesis that rattling is a stress-related behavior. In contrast with Met 5 -enkephalin, ACTH and 尾-endorphin, the correlation...
