摘要:

连续使用吗啡易引发耐受,导致镇痛效果下降及不良反应增多,严重影响临床应用。突触功能可塑性通过谷氨酸能受体介导的钙信号通路、PKA/PKC/MAPK级联及胶质细胞触发的神经炎症信号,调节突触传递效能的持久性变化,促进吗啡耐受的发展。结构可塑性则涉及树突棘密度与形态的动态重塑、突触连接的新增或修剪,以及突触活性区的重构。吗啡处理后,中枢神经系统突触可塑性呈现区域特异性改变,协同推动耐受进程。本文系统综述了突触可塑性在吗啡耐受中的机制研究进展,以期为开发新型镇痛药物和优化临床治疗提供理论依据。

Abstract:

The repeated administration of morphine frequently gives rise to tolerance, manifested by a reduction in analgesic efficacy and an elevation in adverse effects. These consequences significantly impinge upon its clinical utility. Synaptic functional plasticity governs long-term alterations in synaptic transmission efficiency through calcium signaling pathways, protein kinase cascade reactions, and glia-neuron interactions, thereby facilitating the development of morphine tolerance. Structural plasticity encompasses the dynamic remodeling of dendritic spine density and morphology, the establishment or elimination of synaptic connections, and the reconstitution of synaptic active zones. Morphine-induced synaptic plasticity within the central nervous system demonstrates region-specific alterations, which jointly drive the process of tolerance. This review comprehensively synthesizes the research advancements regarding the mechanisms of synaptic plasticity in morphine tolerance, with the aim of furnishing a theoretical foundation for the development of innovative analgesic medications and the optimization of clinical treatment strategies.

Key words: morphine tolerance, synapse, functional plasticity, structural plasticity, central nervous system
