Atypical endogenous opioid systems in mice in relation to an auto-addiction opioid model of anorexia nervosa.

abstract：:Evidence is provided for the abilities of endogenous 6-(Arg or Lys)-opioid peptides to interact with kappa-receptors as agonists. Dynorphin-(1-17) and -(1-8), alpha- and beta-neo-endorphin, [Met5]-enkephalin-Arg6-Phe7 and des acetyl salmon endorphin I significantly inhibited the electrically-evoked contractions of rab...
