Abstract

Worms yield opioid receptor insight The µ-opioid receptor (MOR) is the target of pain-reducing drugs, including morphine and the potent synthetic opioid fentanyl. Better understanding of the receptor system is needed to suppress potentially deadly side effects and manage addiction potential. Wang et al. used a screen in the worm Caenorhabditis elegans to find genes that influenced MOR function (see the Perspective by Mercer Lindsay and Scherrer). They found another receptor called GPR139, loss of which enhanced effects of morphine in mice but reduced withdrawal effects. GPR139 could be a target to improve safety or efficacy of opioid therapy.
