The opioid receptor system is hard-wired into many areas of the brain, as well as the spine and digestive system, and is responsible for triggering responses related to pain control, pleasure and reward. (hellomd.com)
Once produced, endogenous opioids activate receptors that produce physiological changes such as pain relief. (arizona.edu)
Our progress in characterizing bone cancer pain has resulted in twelve direct peer-reviewed publications and preliminary data to further support studies of MAGL inhibition, CB2 receptor activation in bone cancer pain. (grantome.com)
Explore whether MAGLipase inhibition and CB2 receptor activation attenuates breast cancer-induced bone pain by inhibiting pronociceptive cytokines/chemokines via a common transcription factor. (grantome.com)
Cannabinoid receptors can "talk" to and influence opioid receptors and reduce the pain signals sent to the affected areas. (leafwell.com)

Summary: According to researchers, cannabinoids can reduce cravings and help ease withdrawal for those addicted to opioids. (neurosciencenews.com)
The next big breakthrough came in 1988 when researchers discovered the first cannabinoid receptor in mice and humans ( 12 ). (cbdthinker.com)

Further studies need to be conducted in order to test the validity of these findings for human mammals considering the differences between the human and rat cannabinoid systems. (cedfoundation.com)

One of the areas we began to explore was cannabinoids," said Dr. Vanderah, a professor and chair of the Department of Pharmacology in the UArizona College of Medicine - Tucson and member of the BIO5 Institute . (arizona.edu)
