enkephalin receptor การใช้

• Additionally, studies on rats indicate that PCP indirectly interacts with endorphin and enkephalin receptors to produce analgesia.
• In response, brain cells produce more enkephalin receptors on their surface to capture as much of the natural opiate as possible.
• Moreover, the researchers found that increased binding to enkephalin receptors in the brains of cocaine abusers lasted up to a month after withdrawal from the drug.
• By putting radioactive tags on a drug that binds to the same receptors as natural opiates, the researchers showed for the first time that cocaine acts on the enkephalin receptors.
• An increase in the number of unoccupied enkephalin receptors may produce the craving for cocaine experienced by addicts, says Dr . James Frost of Johns Hopkins University, who worked with researchers from the National Institute on Drug Abuse.
• Enkephalin-like peptides have been found in neurones of the palliovisceral lobe of the brain in the common octopus, and met-enkephalin receptors as well as delta opioid receptors in the mantle, arms, gut and vena cava of various octopus species.
