Serotonin and Pain

Brainstem facilitations and descending serotonergic controls contribute to visceral nociception but not pregabalin analgesia in rats.

Pregabalin is used to treat Neuropathic Pain. Here the authors show state-dependent pregabalin analgesia in neuropathy does not apply to visceral pain. Our rabbit polyclonal Mu Opioid Receptor Antibody is used to demonstrate intra-RVM Derm-SAP locally ablates a substantial proportion of MOR and serotonergic cells: Shafaq Sikandar, Kirsty Bannister, Anthony H. Dickenson. Brainstem facilitations and descending serotonergic controls contribute to visceral nociception but not pregabalin analgesia in rats. Neuroscience Letters. Volume 519, Issue 1, 21 June 2012, Pages 31–36.... For MOR staining, a rabbit polycolonal μ-opioid receptor primary antibody (1:10,000 TTBS; Neuromics, MN, USA, RA10104)...

These findings are important for understanding the limitations of Preglabin as an analgesic for viceral pain. Check out all our Opioid Publications.
