Olig2在 cuprizone 介导的脱髓鞘动物模型中的表达变化
Expression pattern of transcription factor Olig2 in cuprizone-induced mouse model of acute demyelination
摘要
Abstract
Objective To investigate the expression pattern of transcription factor Olig 2 in cuprizone-induced mouse model of acute demyelination .Methods C57BL/6 mice were fed with 0.2%cuprizone to induce acute demyelina-tion.Immunofluorescence and qRT-PCR were used, and Olig2, MBP and GFAP were detected in the brain tissues of con-trol group and cuprizone-treated groups for 6 weeks and recovery for 2 weeks.Results Severe demyelination occurred in the corpus callosum following 6-weeks exposure to cuprizone , while remyelination was detected in the white matter after the mice were given diet without cuprizone .In the normal mice , Olig2 was expressed in a low level , while the experessions of Olig2 and GFAP were significantly increased , and Olig2 +/GFAP+cells were detected after demyelination .But the expres-sion of MBP was below the normal level with demyelination .After recovery for 2 weeks, the experession of Olig2 was lower, but the experessions of MBP and GFAP were increased .Conclusions Olig2 may play an important role in the glial differ-entiation from neural progenitor cells into active astrocytes , and in the glial scar formation .关键词
