Attenuation of Antidepressant Effects of Ketamine by Opioid Receptor Antagonism.
OBJECTIVE: In addition to N-methyl-d-aspartate receptor antagonism, ketamine produces opioid system activation. The objective of this study was to determine whether opioid receptor antagonism prior to administration of intravenous ketamine attenuates its

Chronic morphine treatment attenuates cell growth of human BT474 breast cancer cells by rearrangement of the ErbB signalling network. [PDF]
There is increasing evidence that opioid analgesics may interfere with tumour growth. It is currently thought that these effects are mediated by transactivation of receptor tyrosine kinase (RTK)-controlled ERK1/2 and Akt signalling.

Untangling the complexity of opioid receptor function
Mu opioid receptor agonists are among the most powerful analgesic medications but also among the most addictive. The current opioid crisis has energized a quest to develop opioid analgesics that are devoid of untoward effects.

Small-molecule nociceptin receptor agonist ameliorates mast cell activation and pain in sickle mice
Treatment of pain with morphine and its congeners in sickle cell anemia is suboptimal, warranting the need for analgesics devoid of side effects, addiction and tolerance liability. Small-molecule nociceptin opioid receptor ligands show analgesic efficacy

Morphine activates neuroinflammation in a manner parallel to endotoxin [PDF]
Opioids create a neuroinflammatory response within the CNS, compromising opioid-induced analgesia and contributing to various unwanted actions. How this occurs is unknown but has been assumed to be via classic opioid receptors.

Elucidating the active δ-opioid receptor crystal structure with peptide and small-molecule agonists
Crystal structures provide first atomic-level insights into δ-opioid receptor activation by two structurally diverse agonists. Selective activation of the δ-opioid receptor (DOP) has great potential for the treatment of chronic pain, benefitting from ...

Specific down-regulation of spinal μ-opioid receptor and reduced analgesic effects of morphine in mice with postherpetic pain [PDF]
The analgesic effects of opioid agonists and the expression of μ-and κ-opioid receptors were compared between mice with herpetic pain and those with postherpetic pain induced by herpetic virus inoculation.
