Kappa-Opioid Receptor

The kappa-opioid receptor is a type of protein found in the brain and body that interacts with specific chemicals called opioids. It plays a role in regulating pain, stress, and mood. When activated by certain substances, it can produce pain relief and feelings of calmness, but may also cause feelings of dysphoria or discomfort. Researchers are studying these receptors to develop new pain medications that provide relief without the side effects associated with other opioid types, like addiction. Overall, the kappa-opioid receptor is an important part of the body's system for managing pain and emotional responses.
