Revolutionary Research Unveils New Path for Pain Management

A groundbreaking study led by a team from the University of Alberta has uncovered an innovative approach to address post-surgical pain, offering hope for non-addictive treatments that could benefit both animals and humans.

Targeting Pain at its Source

Published in the prestigious journal Anesthesiology, the researchers reported a significant reduction in pain-like behaviors in mice through the chemical inhibition of a specific protein previously identified within neurons of the peripheral nervous system.

The peripheral nervous system plays a crucial role in transmitting signals between the body and the brain, making this discovery particularly exciting.

Meet ERO1: The Protein Behind the Pain

The team focused on a protein known as endoplasmic reticulum oxidoreductin 1 (ERO1), which increases calcium delivery to sensory neurons after injury or surgery. This surge in calcium makes neurons overly sensitive, amplifying pain signals.

Using an injectable drug called EN460, which disrupts ERO1’s calcium delivery, the researchers demonstrated that inhibiting this protein could relieve acute pain symptoms almost instantly.

Transforming Pain Relief in Just an Hour

Lead researcher, Professor Bradley Kerr, noted the swift effectiveness of EN460, stating, "The treatment worked as swiftly as an opioid, leaving the mice remarkably calmer." After nearly 30 years in pain research, he found the results astonishing.

Decoding the Pain Reaction

The researchers observed changes in nociceptive reflexes, which are crucial immediate responses to harmful stimuli, indicating that simply stopping pain signals at their origin can significantly alter the pain experience.

A Collaborative Effort in Pursuit of Pain Science

Kerr emphasized the importance of teamwork in this project, involving various specialists including doctoral student Aislinn Maguire, who spearheaded the research, and other experts who confirmed that EN460 does not possess addictive properties and works effectively as an anesthetic.

The Journey Ahead: From Lab to Clinic

Looking ahead, the team aims to further test EN460 on mice with chronic pain, such as that experienced by individuals with multiple sclerosis. While they have a long way to go before a market-ready product emerges, their mission to find safer alternatives to opioids is firmly on the horizon.
