Researchers from the Turku PET Centre, Finland, have observed that the length of daylight hours impacts opioid receptor levels in brown fat. When daylight hours shorten, the receptor activity levels ...

Two different versions of the mu-opioid receptor within a cellular membrane illustrate how the receptor changes its conformation to send a signal into the cell. Scientists captured six high-resolution ...

Brandy Schillace’s review of “Candace Pert” by Pamela Rykman (Bookshelf, Nov. 15) contains a questionable conclusion: the discovery of the mu opioid receptor in 1972 “helped launch the opioid crisis” ...

Scientists have known for decades that opioids relieve pain by binding to molecular switches in the brain called mu-opioid (pronounced "mew-opioid") receptors. What they didn't know - until now - was ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 119, No. 16 (April 19, 2022), pp. 1-10 (10 pages) Allosteric modulators of G-protein-coupled receptors (GPCRs) ...

Unlike mu, the kappa receptor enables the drugs’ painkilling qualities without lethal side effects, according to a report published in Wired. A growing body of research suggests this receptor could be ...

Muse Treatment Alcohol & Drug Rehab Los Angeles has published a new educational resource that explains how opioid receptors function in the brain and why they play a central role in pain relief, ...

When the season turns darker and colder, animals’ brown fat starts to grow. The tissue produces heat efficiently and rapidly, and regulates appetite. Brown fat is also present in people. In a new ...
