Traumatic brain injury (TBI) is a significant worldwide cause of morbidity and mortality. A chronic neurologic disease bearing the moniker of "the silent epidemic," TBI currently has no targeted therapies to ameliorate cellular loss or enhance functional recovery. Compared with those of astrocytes, microglia, and peripheral immune cells, the functions and mechanisms of NG2-glia following TBI are far less understood, despite NG2-glia comprising the largest population of regenerative cells in the mature cortex. Here, we synthesize the results from multiple rodent models of TBI, with a focus on cortical NG2-glia proliferation and lineage potential, and propose future avenues for glia researchers to address this unique cell type in TBI. As the molecular mechanisms that regulate NG2-glia regenerative potential are uncovered, we posit that future therapeutic strategies may exploit cortical NG2-glia to augment local cellular recovery following TBI.
创伤性脑损伤(TBI)是全球范围内发病率和死亡率的重要原因。作为一种慢性神经系统疾病,被称为“无声的流行病”,TBI 目前尚无靶向疗法来减轻细胞损失或增强功能恢复。尽管 NG2 胶质细胞是成熟皮层中再生细胞数量最多的细胞类型,但与星形胶质细胞、小胶质细胞和外周免疫细胞相比,TBI 后 NG2 胶质细胞的功能和机制仍知之甚少。在这里,我们综合了多个 TBI 啮齿动物模型的研究结果,重点关注皮质 NG2 胶质细胞的增殖和谱系潜能,并为神经胶质细胞研究人员提出了未来解决 TBI 中这一独特细胞类型的途径。随着调节 NG2 胶质细胞再生潜能的分子机制被揭示,我们推测未来的治疗策略可能利用皮质 NG2 胶质细胞来增强 TBI 后局部细胞的恢复。
