Mu-Opioid Receptor

The mu-opioid receptor is a specific protein found in the brain and nervous system that binds to opioids, including natural ones like endorphins and medicinal drugs like morphine. When activated, it helps reduce pain and can produce feelings of euphoria. These receptors also influence breathing, mood, and sedation. They play a crucial role in pain management but can also lead to dependence and addiction if overstimulated by opioids. Understanding these receptors is key to developing pain treatments and addressing opioid addiction issues.
