Myocardial Opioid Receptors in Conditioning and Cytoprotection
Opioid compounds and G-protein coupled opioid receptors (ORs) have been studied widely in terms of central nervous system (CNS) actions relating to pain management and drug abuse. Opioids are also linked to induction of mammalian hibernation, a natural state of tolerance involving prolonged and orchestrated shifts in cellular metabolism, growth and stress resistance. It is not surprising then t...
متن کاملDelta Opioid Receptors: The Link between Exercise and Cardioprotection
This study investigated the role of opioid receptor (OR) subtypes as a mechanism by which endurance exercise promotes cardioprotection against myocardial ischemia-reperfusion (IR) injury. Wistar rats were randomly divided into one of seven experimental groups: 1) control; 2) exercise-trained; 3) exercise-trained plus a non-selective OR antagonist; 4) control sham; 5) exercise-trained plus a kap...
متن کاملAdenosine receptors, heart rate, and cardioprotection.
See article by Fabritz et al. [1] (pages 500-508) in this issue. In this issue of Cardiovascular Research, a paper by Fabritz et al. [1] investigates the effects of controlled overexpression of the A3 adenosine receptor (A3AR) in the mouse heart. Their findings will feed further the current debate on the use of adenosine receptors (AR) as targets for gene therapy aimed at protecting the myocard...
متن کاملOpioid Receptors of the Central Amygdala and Morphine-Induced Antinociception
The amygdala is a forebrain region, which is known as a modulator of pain sensation. The amygdala, particularly the central nucleus, has high concentrations of enkephalins relative to dynorphins and has high concentrations of opioid receptors. We here studied the role of central nuclei of amygdala in morphine antinociception. Methods: In this study, we used 130 male Wistar rats (200- 250g). Bil...
متن کاملOpioid receptors regulate the extinction of Pavlovian fear conditioning.
Rats received a single pairing of an auditory conditioned stimulus (CS) with a footshock unconditioned stimulus (US). The fear (freezing) that had accrued to the CS was then extinguished. Injection of naloxone prior to this extinction significantly impaired the development of extinction. This impairment was mediated by opioid receptors in the brain and was not observed when naloxone was injecte...
