1985: Defining Novel Drug Targets to Treat Chronic and Neuropathic Pain in the Dog

Grant Status: Open

Grant Amount: $69,128
Dr. Ronald Sluyter, Ph.D., University of Wollongong

Breed(s): -All Dogs
Research Program Area: Canine Athlete Initiative


Through previous funding by the AKC Canine Health Foundation, Dr. Ronald Sluyter discovered a novel canine protein named the P2X Receptor. This receptor is responsible for movement of positively charged ions into cells and has been implicated in a wide range of cellular function in humans. Due to its ubiquitous expression and broad-based function, the P2X receptor is thought to play a decisive role in multiple diseases including chronic neuropathic and inflammatory pain, dry eye, irritable bowel syndrome, interstitial cystitis, dysfunctional urinary bladder, and cancer. In this grant Dr. Sluyter will focus on the role of the P2X receptor in pain in the dog. Chronic or long-lasting pain is a major health problem and welfare issue in dogs. Improved understanding of the mechanisms that define chronic pain will greatly aid in the development of new approaches and drugs to alleviate or treat chronic pain in dogs.
