A breakthrough means to ease pain for millions of patients has been discovered by US researchers – and it’s right inside our body.
Scientists at St. Louis University, Missouri, blocked a pain pathway in rodents using a receptor called A3, which is located in rats’ brains and spinal cords, and acts against intense feelings of discomfort.
The latest study was published in the medical journal, Brain.
A3 is activated by adenosine, a native chemical stimulator, or synthetic drugs, and brings pain relief, or prevents pain.
“It has long been appreciated that harnessing the potent pain-killing effects of adenosine could provide a breakthrough step towards an effective treatment for chronic pain,” Daniela Salvemini, Professor of pharmacological and physiological sciences at the university, said, as quoted by the Daily Mail.
