阿片依赖病理过程中NMDA受体与阿片受体的相互作用及分子机制

Cross-talk and molecular mechanisms between NMDA receptor and opioid receptor in opioid dependence

阿片依赖的病理生理学基础与机体长期接触阿片类物质后产生的代偿性适应相关。近年来研究发现 ,NMDA受体拮抗剂、抗体和反义核酸能抑制阿片躯体和精神依赖。该文从神经生化和分子生物学角度 ,综述了NMDA受体作用系统与阿片受体作用系统的相互作用以及NMDA受体参与阿片依赖的分子机制 。

Opioid dependence is based on compensatory adaptations in neurons following chronic exposure to opioids. Recent researches show antagonists of N methyl D aspartate (NMDA) receptors inhibit physical and psychic dependence on opioids. This review focuses on the interactions between opioid receptor system and NMDA receptor system, and on the molecular mechanisms of NMDA receptor contributing to opioid dependence. The clinical prospects of NMDA receptor antagonists and related substances on preventing and treating opioid dependence are aslo discussed.
