Biased signaling by endogenous opioid peptides

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance There are >20 different endogenous opioid peptides derived from the three precursors proopiomelanocortin, proenkephalin, and prodynorphin; a long-standing question is the biological utility of having this variety of peptides.

Impact of different anesthetic protocols during anesthesia for the establishment of a porcine model of acute kidney injury

Animal Models and Experimental Medicine, EarlyView.
This study details the adaptations required to establish a long‐term anesthetic protocol in pigs. Three protocols were evaluated, with some causing malignant hyperthermia, hypoglycemia, or hemoynamic instability. The final protocol proved effective for developing a porcine AKI model requiring adequate arterial pressure maintenance.

μ-Opioid receptor antibody reveals tissue-dependent specific staining and increased neuronal μ-receptor immunoreactivity at the injured nerve trunk in mice. [PDF]

PLoS ONE, 2013
Neuropathic pain is a debilitating chronic disease often resulting from damage to peripheral nerves. Activation of opioid receptors on peripheral sensory neurons can attenuate pain without central nervous system side effects. Here we aimed to analyze the

The atypical chemokine receptor ACKR3/CXCR7 is a broad-spectrum scavenger for opioid peptides

Nature Communications, 2020
Endogenous opioid peptides and prescription opioid drugs modulate pain, anxiety and stress by activating opioid receptors, currently classified into four subtypes. Here we demonstrate that ACKR3/CXCR7, hitherto known as an atypical scavenger receptor for

Peripheral Opioid Receptors

Annals of Medicine, 1995
Recent experimental and clinical research has demonstrated that opioids can produce potent and receptor-specific analgesic effects outside the central nervous system. Opioid receptors are localized on peripheral terminals of sensory nerves and their endogenous ligands, opioid peptides, have been discovered in immune cells within inflamed tissue.

μ‐Opioid Receptor Dynamics in the Parameningeal Tissue During Migraine Attacks

Annals of Neurology, EarlyView.
Objective The possible impact of meningeal μ‐opioid receptor (μOR) binding in migraine remains unknown. This study investigated μOR availability in the cranial parameninges involved in migraine initiation via nociceptor activation. Methods We used positron emission tomography with [11C] carfentanil, and measured μOR availability in meninges and ...

Contemporary management of pain in cirrhosis: Toward precision therapy for pain

Hepatology, EarlyView., 2022
Abstract Chronic pain is highly prevalent in patients with cirrhosis and is associated with poor health‐related quality of life and poor functional status. However, there is limited guidance on appropriate pain management in this population, and pharmacologic treatment can be harmful, leading to adverse outcomes, such as gastrointestinal bleeding ...

Structural insights into μ-opioid receptor activation

Nature, 2015
Activation of the μ-opioid receptor (μOR) is responsible for the efficacy of the most effective analgesics. To shed light on the structural basis for μOR activation, here we report a 2.1 Å X-ray crystal structure of the murine μOR bound to the morphinan ...

GRKs as Key Modulators of Opioid Receptor Function

Cells, 2020
Understanding the link between agonist-induced phosphorylation of the mu-opioid receptor (MOR) and the associated physiological effects is critical for the development of novel analgesic drugs and is particularly important for understanding the ...

Health disparities in chronic liver disease

Hepatology, EarlyView., 2022
Abstract The syndemic of hazardous alcohol consumption, opioid use, and obesity has led to important changes in liver disease epidemiology that have exacerbated health disparities. Health disparities occur when plausibly avoidable health differences are experienced by socially disadvantaged populations.
