They said they discovered how specific natural opioid peptides recognize and activate these receptors. In some experiments, they also used drug-like compounds to see how they activated the receptors.
Opioid receptors are of major medical interest because opioids influence pain perception. (Shutterstock) A worldwide team of experts investigated the molecular mechanisms of these active compounds.
Patients with fibromyalgia got no more pain relief from low-dose naltrexone than from placebo in a randomized trial, researchers said, dashing hopes that the opioid receptor antagonist might ...
Researchers have revealed a previously unknown function of opioid receptors in the development of the enteric nervous system (ENS), often referred to as the 'brain in the gut.' This discovery ...
