摘要:

脊髓损伤是一种不可逆的中枢神经系统损伤,其特征是再生能力有限和继发性炎症损伤。CCL2/CCR2轴的表达在脊髓损伤前后存在显著差异。最近有研究认为,CCL2/CCR2轴与脊髓损伤后继发性炎症反应和免疫细胞募集密切相关,这表明CCL2/CCR2轴可能是脊髓损伤的一个新的治疗靶点和调节节点。此次综述总结了CCL2/CCR2轴与脊髓损伤再生修复机制,概括了脊髓损伤与CCL2/CCR2轴相关的上下游炎症相关信号通路,重点阐述了针对CCL2/CCR2通路的治疗策略与最新拮抗药物的研究进展和有关CCL2/CCR2轴作为新治疗靶点的调控方式以及靶向药物的开发,这将为未来脊髓损伤治疗提供了新的思路和治疗策略。

Abstract: Spinal cord injury involves non-reversible damage to the central nervous system that is characterized by limited regenerative capacity and secondary inflammatory damage. The expression of the C–C motif chemokine ligand 2/C–C motif chemokine receptor 2 axis exhibits significant differences before and after injury. Recent studies have revealed that the C–C motif chemokine ligand 2/C–C motif chemokine receptor 2 axis is closely associated with secondary inflammatory responses and the recruitment of immune cells following spinal cord injury, suggesting that this axis is a novel target and regulatory control point for treatment. This review comprehensively examines the therapeutic strategies targeting the C–C motif chemokine ligand 2/C–C motif chemokine receptor 2 axis, along with the regenerative and repair mechanisms linking the axis to spinal cord injury. Additionally, we summarize the upstream and downstream inflammatory signaling pathways associated with spinal cord injury and the C–C motif chemokine ligand 2/ C–C motif chemokine receptor 2 axis. This review primarily elaborates on therapeutic strategies that target the C–C motif chemokine ligand 2/C–C motif chemokine receptor 2 axis and the latest progress of research on antagonistic drugs, along with the approaches used to exploit new therapeutic targets within the C–C motif chemokine ligand 2/C–C motif chemokine receptor 2 axis and the development of targeted drugs. Nevertheless, there are presently no clinical studies relating to spinal cord injury that are focusing on the C–C motif chemokine ligand 2/C–C motif chemokine receptor 2 axis. This review aims to provide new ideas and therapeutic strategies for the future treatment of spinal cord injury.
