  • Title: Multiple opioid receptors: evidence for mu-delta binding site interactions in endotoxic shock.
    Author: Holaday JW, D'Amato RJ.
    Journal: Life Sci; 1983; 33 Suppl 1():703-6. PubMed ID: 6319921.
    Abstract:
    Using antagonists with selectivity for the delta (ICI 154,129) and mu (beta-funaltrexamine) binding sites, evidence was obtained to indicate that delta receptors within the brain mediate the endogenous opioid component of endotoxic hypotension. The therapeutic actions of intravenous ICI 154,129 were dose related, with effective doses between 15-60 mg/kg. Evidence for a functional interaction between mu and delta binding sites was obtained: prior occupancy of the mu binding site by beta-funaltrexamine prevented the usual therapeutic response to the delta antagonist ICI 154,129 in endotoxemic rats. These data indicate that mu and delta binding sites may be a part of the same macromolecular complex which interact through allosteric coupling.
