[Research] New target for chronic pain relief confirmed by scientists

Scientists observe drug target that can reduce pain when activated

A research group at Hiroshima University observed a potential new target for chronic pain treatment. Further research using this receptor could lead to new, more effective drugs to use in pain-relieving treatment for chronic pain.

Normal pain transmission triggers signaling modules to cause a sensation of pain. In chronic pain, activated astrocytes cause an increase in production of these signaling molecules, which leads to more intense or longer-lasting pain. The main finding of the study shows that simulating REV-ERBs in spinal cord astrocytes with an agonist leads to pain relief. (Diagram by Professor Morioka)
