摘要:

脊髓损伤是一种严重的中枢系统损伤,会导致持续的神经功能缺陷,其主要治疗方法为手术、药物和康复疗法。然而,这些方法都不能显著逆转神经功能障碍。最近,各种细胞来源的细胞外囊泡已被运用于不同的脊髓损伤模型,这为治疗脊髓损伤开辟了新的无细胞疗法。单独使用细胞外囊泡仍然存在着明显的不足,因此此次综述基于细胞外囊泡的最新的联

Abstract: Spinal cord injury is a severe insult to the central nervous system that causes persisting neurological deficits. The currently available treatments involve surgical, medical, and rehabilitative strategies. However, none of these techniques can markedly reverse neurological deficits. Recently, extracellular vesicles from various cell sources have been applied to different models of spinal cord injury, thereby generating new cell-free therapies for the treatment of spinal cord injury. However, the use of extracellular vesicles alone is still associated with some notable shortcomings, such as their uncertainty in targeting damaged spinal cord tissues and inability to provide structural support to damaged axons. Therefore, this paper reviews the latest combined strategies for the use of extracellular vesicle-based technology for spinal cord injury, including the combination of extracellular vesicles with nanoparticles, exogenous drugs and/or biological scaffold materials, which facilitate the targeting ability of extracellular vesicles and the combinatorial effects with extracellular vesicles. We also highlight issues relating to the clinical transformation of these extracellular vesicle-based combination strategies for the treatment of spinal cord injury.
