Small sensory neurons in the rat dorsal root ganglia express functional NK-1 tachykinin receptor.

Abstract

The tachykinins substance P (SP) and neurokinin A, released by the C-type primary afferent fibre terminals of the small dorsal root ganglion (DRG) neurons, play important roles in spinal nociception. By means of non-radioactive in situ hybridization and whole-cell recording, we showed that the small rat DRG neurons also express the NK-1 tachykinin receptor… (More)
