Abstract
The uptake of 45Ca2+ by nerve-ending fractions from brains of mice was inhibited in vitro by 10(-9)M concentrations of beta-endorphin and in mice injected intraventricularly with 7 picomoles of beta-endorphin. That the effect was a specific opiate agonist response of beta-endorphin was demonstrated by use of the opiate antagonist, naloxone, which reversed the action. A role for beta-endorphin in the regulation of calcium flux and neurotransmitter release should be considered.Keywords
