Neuropeptide Y neurons mediate opioid-induced itch by disinhibiting GRP-GRPR microcircuits in the spinal cord
Abstract Itch is a common side effect of opioid analgesics. The specific neurons mediating opioid-induced itch are still debated, and the mechanistic neuronal circuits remain elusive. Here, we show that the μ-opioid receptors (MOR) on neuropeptide Y (NPY)+ inhibitory interneurons mediate opioid-indu...
