Sikandar S, Bannister K, Dickenson AH (2012) Brainstem facilitations and descending serotonergic controls contribute to visceral nociception but not pregabalin analgesia in rats. Neurosci Lett 519(1):31-36. doi: 10.1016/j.neulet.2012.05.009
Summary: Neurons in the rostral ventromedial medulla (RVM) are classified as ON, OFF, or NEUTRAL based on firing patterns in response to noxious somatic stimulation. ON cells express μ-opioid receptors, and are therefore a target for dermorphin-SAP (Cat. #IT-12). The authors injected the RVM of rats with 3 pmol of dermorphin-SAP; Saporin (Cat. #PR-01) was used as a control. Results show the μ-opioid receptor population is not needed for the function of analgesics through the serotonergic system.
