Spinal bombesin-recognized neurones mediate more nonhistaminergic than histaminergic sensation of itch in mice.

Spinal bombesin-recognized neurones mediate more nonhistaminergic than histaminergic sensation of itch in mice.

Han N, Zu JY, Chai J (2012) Spinal bombesin-recognized neurones mediate more nonhistaminergic than histaminergic sensation of itch in mice. Clin Exp Dermatol 37(3):290-295. doi: 10.1111/j.1365-2230.2011.04314.x

Summary: The authors administered 400 ng of Bombesin-SAP (Cat. #IT-40) to the lumbar spinal subarachnoid space of rats and evaluated the distribution of Fos-positive cells in the dorsal horn after stimulation. Saporin (Cat. #PR-01) was used as a control. The results demonstrate that the neurons eliminated by Bombesin-SAP are critical to both acute and chronic itch pathways, although they have more effect on nonhistaminergic sensation.
