Lemons LL, Wiley RG (2012) Neuropeptide Y receptor-expressing dorsal horn neurons: role in nocifensive reflex and operant responses to aversive cold after CFA inflammation. Neuroscience 216:158-166. doi: 10.1016/j.neuroscience.2012.04.006 PMID: 22522467
Objective: To determine the role of dorsal horn Y1R-expressing neurons in pain.
Summary: Lumbar intrathecal NPY-SAP (1) reduced Complete Freund’s Adjuvant (CFA)-induced hyper-reflexia on the 10°C cold plate, (2) reduced cold aversion on the thermal preference and escape tasks, (3) was analgesic to noxious heat on the escape task, (4) reduced the CFA-induced allodynia to cold temperatures experienced on the thermal preference, feeding interference, and escape tasks, and (5) did not inhibit or interfere with morphine analgesia.
