Gliosis is a nonspecific reactive change of glial cells in response to damage to the central nervous system(CNS).In most cases, gliosis involves the proliferation orhypertrophy of several different types of glial cells,including astrocytes,microglia,and oligodendrocytes. It is thought that the glial scar limits edema and prevents neuronal regeneration in the CNS by blocking regenerating axons from entering the damaged areas. 胶质增生是神经胶质细胞对中枢神经系统（CNS）损伤的一种非特异性反应。在大多数情况下，胶质增生涉及几种不同类型神经胶质细胞的增生或肥大，包括星形胶质细胞、小胶质细胞和少突胶质细胞。 这被认为是神经胶质瘢痕通过阻止再生轴突进入受损区域来限制水肿并阻止CNS中的神经元再生。 (刘晓雯翻译，读片哥编辑整理) |
