The direct comparison of mice lacking each of the three opioid-receptor genes reveals that mu- and delta-opioid receptors act oppositely in regulating emotional reactivity. This highlights a novel ...

New findings show that heavy drinkers with the G allele of the A118G polymorphism of the mu-opioid receptor gene have greater cravings after alcohol exposure than heavy drinkers homozygous for the ...

Those attempts were doomed to failure because all opioid drugs interact with the brain in the same way. They dock to a specific neural receptor, the mu-opioid receptor, which controls the effects ...

Fentanyl, a mu-opioid receptor agonist, is one of the most commonly used analgesics in hospitals, and may induce long-lasting behavioral and somatosensory impairment in rodents. However ...

Professor Anne Roivainen from the Turku PET Centre tells that this is the first time mu-opioid receptor levels have been assessed in peripheral regions using positron emission tomography (PET ...

Naloxone is a competitive antagonist at the mu-opioid receptor. It is thought to reduce the intensity of itching through antagonism of the mu-opioid receptor both centrally and peripherally ...

Your body has three primary opioid receptor types: mu, delta, and kappa. These receptors are found on the surface of cells in the central and peripheral nervous systems. They respond to your body ...

New findings show that heavy drinkers with the G allele of the A118G polymorphism of the mu-opioid receptor gene have greater cravings after alcohol exposure than heavy drinkers homozygous for the ...

The main ones are mu, kappa, and delta. Partial opioid agonists can act on any opioid receptor. Unlike a full agonist, which can cue a cell to produce the maximum opioid effect, partial agonists ...
