Itch signaling in the nervous system.

Jeffry J, Kim S, Chen ZF (2011) Itch signaling in the nervous system. Physiology (Bethesda) 26(4):286-92. doi: 10.1152/physiol.00007.2011

Summary: This review examines recent work done to elucidate the molecular mechanisms behind the sensation of itch. The progress of mouse genetics has allowed the field to move beyond clinical and physiological studies, toward a better understanding of the signaling involved in nonhistaminergic itch. One study discussed used bombesin-SAP (Cat. #IT-40) in mice to ablate GRPR-positive neurons in the dorsal horn. This lesion reduced scratching in response to pruritogens, but did not affect pain behavior‚ indicating that pain and itch use entirely different pathways.
