星形胶质细胞为中枢神经系统的主要支持成分 ,参与多种生理及病理功能。各种神经损害往往使其激活并增生 ,成为反应性星形胶质细胞。此时它会发生一系列形态学和功能的变化 ,对病理条件下神经的损伤及修复产生重要影响。本文主要就其在脑损伤中的表现及意义做一综述 Astrocytes are the main supportive components of the central nervous system and are involved in a variety of physiological and pathological functions. A variety of nerve damage often activates and proliferates, becoming reactive astrocytes. At this point it will occur a series of morphological and functional changes, pathological conditions of nerve damage and repair have a significant impact. This article mainly reviews its performance and significance in brain injury
