Structures of the entire human opioid receptor family.
Cell, 2023 Opioids are effective analgesics, but their use is beset by serious side effects, including addiction and respiratory depression, which contribute to the ongoing opioid crisis.

Molecular mechanisms of opioid tolerance: From opioid receptors to inflammatory mediators (Review)
Experimental and Therapeutic Medicine, 2021 Opioids are considered the most effective analgesics for the treatment of both acute and chronic pain. However, prolonged opioid use can induce a certain level of tolerance to its analgesic effects, leading to a reduction in its effectiveness, addiction ...

Pharmaceuticals, 2022 This paper proposes the design of combination opioid–adrenergic tethered compounds to enhance efficacy and specificity, lower dosage, increase duration of activity, decrease side effects, and reduce risk of developing tolerance and/or addiction ...

Bidirectional Regulation of Opioid and Chemokine Function
Frontiers in Immunology, 2020 The opioid family of GPCRs consists of the classical opioid receptors, designated μ-, κ-, and δ-opioid receptors, and the orphanin-FQ receptor, and these proteins are expressed on both neuronal and hematopoietic cells.

Cocaine modulates the expression of opioid receptors and miR-let-7d in zebrafish embryos. [PDF]
PLoS ONE, 2012 Prenatal exposure to cocaine, in mammals, has been shown to interfere with the expression of opioid receptors, which can have repercussions in its activity.

Estradiol and Mu opioid-mediated reward: The role of estrogen receptors in opioid use
Addiction Neuroscience, 2023 Opioid use and opioid use disorder are characterized by sex and gender differences, and some of these differences may be mediated by differences in the hormonal milieu within and across individuals.

Chronic morphine treatment attenuates cell growth of human BT474 breast cancer cells by rearrangement of the ErbB signalling network. [PDF]
, 2013 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.
