脊髓损伤(SCI)常导致永久性残疾,其主要原因是丧失功能恢复能力。在这篇综述中,我们的目的是研究愈合过程中断的原因。这种中断的原因之一是在严重受损的组织周围形成胶质疤痕,通常被反应性胶质细胞、巨噬细胞和成纤维细胞覆盖。为了澄清这一问题,我们总结了有关疤痕形成、组织修复的最新研究成果,以及血源性单核/巨噬细胞、室管膜细胞、成纤维细胞、小胶质细胞、少突胶质细胞祖细胞(OPCs)、神经胶质抗原2 (NG2)和星形胶质细胞在疤痕形成过程中的不同作用,并进一步分析了这些细胞对疤痕形成的贡献。此外,我们概述了针对胶质瘢痕成分的治疗方法的发展。总之,我们的目标是提供一个全面的解码神经胶质疤痕和探索潜在的治疗策略,以改善脊髓损伤后的功能恢复。
Spinal cord injury (SCI) often leads to permanent disability, which is mainly caused by the loss of functional recovery. In this review, we aimed to investigate why the healing process is interrupted. One of the reasons for this interruption is the formation of a glial scar around the severely damaged tissue, which is usually covered by reactive glia, macrophages and fibroblasts. Aiming to clarify this issue, we summarize the latest research findings pertaining to scar formation, tissue repair, and the divergent roles of blood-derived monocytes/macrophages, ependymal cells, fibroblasts, microglia, oligodendrocyte progenitor cells (OPCs), neuron-glial antigen 2 (NG2) and astrocytes during the process of scar formation, and further analyse the contribution of these cells to scar formation. In addition, we recapitulate the development of therapeutic treatments targeting glial scar components. Altogether, we aim to present a comprehensive decoding of the glial scar and explore potential therapeutic strategies for improving functional recovery after SCI.
