Description
Abstract: Animal models are critical to the understanding of pain biology and development of
effective therapeutics. To date, basic and translational research in pain has predominantly been done
using rodent models. These models have substantially advanced the field of pain research, and their
utility for drug discovery has been well-documented. However, limitations remain regarding the value
of rodent models to accurately predict analgesic efficacy in human clinical populations, which may be
due in part to species differences. Additional models are needed to address gaps for pain conditions
that cannot or have not been adequately modeled in rodents due to, for example, anatomical
considerations, species-specific pharmacology, the discordant time course of disease progression, or
lack of diversity of experienced symptoms often associated with human pain conditions. Non-rodent
mammalian models such as swine have similarities to humans in genetics, anatomy, size,
metabolism, and physiology that may be advantageous for their recapitulation of certain disease
phenotypes. These model systems also present unique translational opportunities for developing and
testing novel devices and pain therapies for humans. The goal of this proposal is to develop,
characterize, and rigorously validate a pig model of spinal cord injury (SCI) pain including associated
outcome measures and/or endpoints to significantly advance translational research for effective pain
management. Regarding associative measures, intraspinal inflammation is a well-established
hallmark of SCI pain. Additional established cellular targets for analgesic therapies include intraspinal
axonal reorganization and sprouting with SCI-increasing calcitonin gene-related peptide (CGRP)
sprouting into the dorsal horn in humans. We will use morphological and anatomical quantification
techniques to evaluate inflammatory responses and other indicators of central sensitization in the pig
spinal cord in response to analgesic therapies.
