| 中文摘要: |
| 星型胶质细胞在突触形成、神经元代谢、神经递质传递等方面起重要作用，其退行性病变可引起突触蛋白水平降低、神经元
体积减小及神经递质传递异常，进而引起神经精神性疾病的发生。抑郁症患者前额叶皮层、海马、杏仁核以及前扣带回等多个脑
区均有星型胶质细胞密度减低，提示星形胶质细胞与抑郁症发病密切相关。研究表明，能量和营养支持、谷氨酸(glutamate，Glu)转
运和代谢、N- 甲基-D- 天(门) 冬氨酸（N-methyl-D-aspartate，NMDA）受体活性调节以及炎症反应异常等星形胶质细胞功能障碍参
与抑郁症的发生。本文就星形胶质细胞功能障碍在抑郁症发病机理中的作用进行综述。 |
| 英文摘要: |
| Depression is a common mood disorder, but the pathogenesis is still unclear completely. Astrocytes play an important
role in providing nutritional support to the formation of synapses, neuronal metabolism and neurotransmission. Therefore, astrocytes
degeneration could be responsible for the reducing of the levels of synaptic protein, neuronal size and the abnormalities of
neurotransmission. Postmortem studies of brains of the depressed patients showed a decrease in the density of astrocytes in prefrontal
cortex, hippocampus, amygdale and anterior cingulated, suggesting that astrocytes are probably related to the onset of depression. There
is mounting evidence indicates that the dysfunction of astrocyte in supporting of energy and neurotrophy, the transportation and
metabolism of glutamate, the regualation of N-methyl-D-aspartate receptor activity and the inflammation is a key element in the
pathogenesis of depression. We will review the effects of astrocyte dysfunction during the onset of depression. |
