SINGAPORE (Reuters) - Researchers working on mice have found an enzyme in the brain that appears to make pain last after nerve injury and they hope to use it as a new target to treat chronic pain in people.
In a paper published in Science magazine Friday, the scientists in Canada and South Korea said they managed to alleviate pain after blocking the enzyme.
"It provides us with basic understanding of the brain mechanism for chronic pain," lead author Min Zhuo, a physiology professor at the University of Toronto, wrote in an email.
"It not only provides a new possibility to design new pain medicine, but it also helps us to understand why many drugs fail to control chronic pain."
