An additional opioid receptor was later identified and cloned based on homology with the cDNA. This receptor is known as the nociceptin receptor or ORL1 (opiate receptor-like 1). The opioid receptor types are nearly 70% identical, with the differences located at the N and C termini. The μ receptor is perhaps the most important.
The neurotransmitters implicated in the control of nausea and vomiting include acetylcholine, dopamine, histamine (H1 receptor), substance P (NK-1 receptor), and serotonin (5-HT3 receptor). There are also opioid receptors present, which may be involved in the mechanism by which opiates cause nausea and vomiting.

The κ-opioid receptor or kappa opioid receptor, abbreviated KOR or KOP for its ligand ketazocine, is a G protein-coupled receptor that in humans is encoded by the OPRK1 gene. The KOR is coupled to the G protein G i /G 0 and is one of four related receptors that bind opioid -like compounds in the brain and are responsible for mediating the ...
The activation of the mu-opioid receptor inhibits the release of substance P from these incoming first-order neurons and, in turn, inhibits the activation of the second-order neuron that is responsible for transmitting the pain signal up the spinothalamic tract to the ventral posterolateral nucleus (VPL) of the thalamus.

β-Endorphin is an agonist of the opioid receptors; it preferentially binds to the μ-opioid receptor. [1] Evidence suggests that it serves as a primary endogenous ligand for the μ-opioid receptor , [ 1 ] [ 10 ] the same receptor to which the chemicals extracted from opium , such as morphine , derive their analgesic properties. β-Endorphin ...
