Do you suffer from chronic pain like four in every 10 Americans?

If so, findings from a CU-Boulder-led research team could change the way chronic pain is treated with drugs such as morphine, which has been around since the 1850s. The United States is one of the world鈥檚 highest users of morphine.

CU researchers have discovered that two proteins in the central nervous system team up to respond to morphine and cause unwanted neuroinflammation. As a result, morphine and similar so-called 鈥渙pioid analgesics鈥� actually can enhance pain by increasing the excitability of neurons in the pain pathway.

鈥淲e have shown this protein complex essentially cuts morphine off at the knees, preventing it from doing its job in controlling pain,鈥� says Linda Watkins, distinguished professor of psychology, a co-author of the study.

This finding may help researchers develop new drugs that could offer increased effectiveness by decreasing neuroinflammation and minimizing some of morphine鈥檚 side effects that include addiction to the drug. The CU discovery is critical given that chronic pain sufferers cost the nation as much as $635 billion annually in lost productivity and health care expenses.

CU-Boulder researchers have been working with the CU Technology Transfer Office and have filed a group of related patents on potential therapeutics for optimizing current pain management therapies, according to assistant professor of chemistry and biochemistry Hang 鈥淗ubert鈥� Yin.
