Methionine-Enkephalin Stimulates Hydrogen Peroxide and Nitric Oxide Production in Rat Peritoneal Macrophages: Interaction of μ, δ and κ Opioid Receptors

Abstract

It is concluded that both negative and positive functional interaction between delta, mu and kappa opioid receptors regulate the influence of MET on H(2)O(2) and NO production in rat peritoneal macrophages.
