A neuropeptide code for itch
ZF Chen - Nature Reviews Neuroscience, 2021 - nature.com
Itch is one of the most primal sensations, being both ubiquitous and important for the well-

Recent advances in our understanding of the organization of dorsal horn neuron populations and their contribution to cutaneous mechanical allodynia
The dorsal horns of the spinal cord and the trigeminal nuclei in the brainstem contain neuron
populations that are critical to process sensory information. Neurons in these areas are …

Central opioid receptors mediate morphine-induced itch and chronic itch via disinhibition
Opioids such as morphine are mainstay treatments for clinical pain conditions. Itch is a
common side effect of opioids, particularly as a result of epidural or intrathecal …
