小胶质细胞在中枢神经系统炎症性疾病中起重要作用。有证据表明,具有不同表型的小胶质细胞多样性表现出神经保护和修复或神经毒性。然而,这种多样性背后的精确分子机制尚不清楚。利用实验性自身免疫性脑脊髓炎(EAE)模型,我们对EAE急性和慢性疾病期分离的室下区小胶质细胞进行了转录谱分析。我们发现小胶质细胞表现出疾病阶段特定的基因表达特征,这与独特的基因本体功能和基因组网络相对应。我们的数据首次证明了体内小胶质细胞激活的不同转录网络,这表明它作为损伤或修复介质的作用。
Microglia play an important role in inflammatory diseases of the central nervous system. There is evidence of microglial diversity with distinct phenotypes exhibiting either neuroprotection and repair or neurotoxicity. However the precise molecular mechanisms underlying this diversity are still unknown. Using a model of experimental autoimmune encephalomyelitis (EAE) we performed transcriptional profiling of isolated subventricular zone microglia from the acute and chronic disease phases of EAE. We found that microglia exhibit disease phase specific gene expression signatures, that correspond to unique gene ontology functions and genomic networks. Our data demonstrate for the first time, distinct transcriptional networks of microglia activation in vivo, that suggests a role as mediators of injury or repair.
