Objective
"Pain is more than a symptom, it can develop into a disabling disease. Amylin is a hormone with several metabolic effects that has shown to also influence the nociceptive system. The literature is however contradicting as some authors claim to find analgesic effects under amylin treatment, while others suggest no action or a pronociceptive role for this hormone. As chronic pain involves pathophysiological mechanisms diverse from the physiological ones occurring in acute pain, it is possible that amylin plays a different role in either condition.
Therefore, in this project we aim at determining potential antinociceptive or pronociceptive effects of amylin in multiple pain models in rats (acute, sustained, chronic inflammatory and neuropathic pain). Also, we will evaluate whether the reduction on amylin levels observed in streptozotocin-induced diabetes plays a role on the development of diabetic neuropathy and if these rats show alterations in the dorsal root ganglion amylinergic system. Finally, we will assess whether nociception is altered in animals lacking amylin (KO mice). Standard thermal and mechanical acute pain tests will be employed, as well as the monoarthritis and the spared nerve injury models of chronic inflammatory and neuropathic pain, respectively. To clarify if the effects are really amylin-receptor mediated, we will use a specific amylin receptor antagonist. Amylin’s effect on the nociceptive-responsive spinal cord neurons will be analysed by c-Fos protein expression. Colocalization of amylin and opioid receptors in spinal cord dorsal horn neurons will assess if this is the site of amylin synergy with morphine in visceral pain.
Amylin is a physiological hormone and its commercial analogue (pramlintide) has proven to be safe in diabetic patients, implying that it may be suitable for treating patients with pain. Therefore we hope to discover analgesic properties in amylin with the current study in the search for new therapeutic alternatives for pain."
