Selective ablation of dorsal horn NK(1) expressing cells reveals a modulation of spinal alpha2-adrenergic inhibition of dorsal horn neurones.

Rahman W, Suzuki R, Hunt SP, Dickenson AH (2008) Selective ablation of dorsal horn NK(1) expressing cells reveals a modulation of spinal alpha2-adrenergic inhibition of dorsal horn neurones. Neuropharmacology 54:1208-1214. doi: 10.1016/j.neuropharm.2008.03.014

Summary: In this work the spinal origin of the major descending noradrenergic inhibitory pathway is examined with the help of SP-SAP (Cat. #IT-07). Rats received a 10-µl infusion of 1-mM SP-SAP (saporin, Cat. #PR-01, was used as a control) into the sub-arachnoid space terminating in the L4-5 region. Results from examining neuronal responses under the influence of the alpha2-adrenoceptor antagonist atipamezole suggest that NK1 expressing cells are involved with activity in noradrenergic pathways and descending facilitation.
