- An opioid receptor is a type of protein found on the surface of neurons in the nervous system that can bind to opioid molecules, such as endorphins, enkephalins, and morphine. There are three main types of opioid receptors: mu-, delta-, and kappa-opioid receptors, each with a different distribution in the brain and different physiological functions. Opioid receptors are G protein-coupled receptors, meaning that they interact with and activate a type of protein called a G protein, which can initiate intracellular signaling pathways to modulate neuron activity. The activation of opioid receptors can lead to a variety of physiological effects, such as pain relief, sedation, euphoria, and respiratory depression. Opioid receptors are also involved in the development of opioid tolerance and opioid addiction, as well as in the therapeutic effects of opioid drugs used to treat pain and addiction.
