Abstract Opioid peptides are a group of neuropeptides which include enkephalins, endorphins and dynorphins. In addition to their central and peripheral antinociceptive function, opioids can modulate immune activity and cell proliferation. Previously, we have shown that enkephalins are present in ...
The main objective of the current study was to examine the possible genetic relationship between intermale aggression and brain levels of enkephalins, endorphins, and dynorphins in 11 inbred strains of mice. Pursuit, rattling, and attack behaviors were observed in a dyadic encounter with a standard...
It is now clear that there are at least three different families of endogenous opioid peptides, the enkephalins, endorphins and dynorphins. These peptides may function as neurotransmitters, neurohormones or hormones. In addition the receptor-mediated actions of these opioid peptides show a considerab...

The endogenous opioid peptides all contain the enkephalin sequence Tyr-Gly-Gly-Phe-Met and Tyr-Gly-Gly-Phe-Leu at their amino terminus. Three distinct families of these peptides (endorphins, enkephalins and dynorphins) are present in different neuronal pathways within the CNS. Molecular genetics ...
complex interplays between endogenous opioid peptides targetingμ-receptors, such as enkephalins and endorphins, underlying the regulation of feeding and body weight that might explain the poor efficacy of drugs that generally targetμ-opioid receptors in the long-term control of appetite and body ...
dynorphinsinbred micePrevious studies suggest that brain opioid activity decreases aggression in animal models. The main objective of the current study was to examine the possible genetic relationship between intermale aggression and brain levels of enkephalins, endorphins, and dynorphins in 11 inbred ...
