摘要 在中枢神经系统,外部感染等引起的炎症反应中起重要作用的是由活化的胶质细胞产生的炎性因子,包括促炎因子(如白细胞介素1,6、肿瘤坏死因子-α、干扰素、趋化因子等)和抗炎因子(如白细胞介素4,10、转化生长因子β等)。海马作为学习和记忆相关的重要结构,其神经元再生受损可能与年老所致认知功能下降以及阿尔兹海默病、抑郁等疾病有关。而中枢神经系统炎症作为大脑损伤及许多神经退行性病变的并发症,对神经元再生的影响已引起了广泛的关注。炎性因子的种类、释放的时间及含量不同,可对神经元再生产生不同的影响。 In the central nervous system, infections and trauma may result in inflammation. The inflammatory cytokines produced by activated glial cells include pro-inflammatory cytokines (e. g. , interleukin-1 & 6, tumor necrosis factor-α, interferon, chemokines, etc. ) and anti-inflammatory cytokines (e. g. , interleukin-4 & 10, transforming growth factor β, etc. ). Adult neurogenesis is subject to the modulation by various physiological and pathological stimuli. Hippocampus is important for some forms of learning and memory functions, and the defects of hippoeampal neurogenesis could be associated with aging related cognitive decline, Alzheimer's disease, depression and other diseases. However, as the complications of brain trauma and neurodegeneration, central nervous system inflammation has attracted wide attentions. With special types, releasing time and content, inflammatory eytokines play different roles in neurogenesis.
