‘Off switch’ for pain discovered: Activating the adenosine A3 receptor subtype is key to powerful pain relief

The scientific efforts led by Salvemini, who is professor of pharmacological and physiological sciences at SLU, demonstrated that turning on a receptor in the brain and spinal cord counteracts chronic nerve pain in male and female rodents. Activating the A3 receptor — either by its native chemical stimulator, the small molecule adenosine, or by powerful synthetic small molecule drugs invented at the NIH — prevents or reverses pain that develops slowly from nerve damage without causing analgesic tolerance or intrinsic reward (unlike opioids). An Unmet Medical Need Pain is an enormous problem…
