摘要
Endomorphin-1 and -2, recently isolated endogenous peptides specific for the mu-opioid receptor, inhibited Ca2+ channel currents with EC50 of 6 and 9 nM, respectively, in NG108-15 cells transformed to express the cloned rat mu-opioid receptor. On the other hand, they elicited no response in nontransfected NG108-15 cells. It is concluded that endomorphin-1 and -2 induce Ca2+ channel inhibition by selectively activating the mu-opioid receptor. (C) 1997 Elsevier Science B.V.
