Project Summary

Chronic or long-lasting pain is a major health problem and welfare issue in dogs. Chronic pain results from disease, injury or aging. Evidence from humans and rodents strongly implicates an important role for a group of molecules (termed P2X receptors) on white blood cells (within the bone joints, spinal cord and other body parts) in chronic pain. The roles of P2X receptors in dogs however remain poorly understood. Therefore, the proposed project aims to determine the roles of these receptors and how they contribute to chronic pain in dogs. Improved understanding of the factors that contribute to chronic pain will greatly aid in the development of new approaches and drugs to alleviate or treat chronic pain in dogs. We have determined that dogs express P2X4 receptors and that the gene coding this receptor is highly conserved between dogs, suggesting it may be a potential drug target to treat chronic pain in these animals.
