發(fā)布時(shí)間:2021-03-31 08:22
目的:研究星形膠質(zhì)細(xì)胞活化后神經(jīng)生長(zhǎng)因子(nerve growth factor,NGF)、白細(xì)胞介素-6(interleukin-6,IL-6)表達(dá)的時(shí)間規(guī)律性,探討星形膠質(zhì)細(xì)胞活化后啟動(dòng)保護(hù)性機(jī)制與損傷性機(jī)制的時(shí)間特性。方法:體外分離培養(yǎng)星形膠質(zhì)細(xì)胞,分為對(duì)照組、活化組、抑制組。通過(guò)光學(xué)顯微鏡及免疫熒光化學(xué)觀察各組細(xì)胞的形態(tài)變化;應(yīng)用半定量RT-PCR方法分析各組細(xì)胞間膠原纖維酸性蛋白(glial fibrillary acidic protein,GFAP)mRNA及NGF mRNA、IL-6 mRNA表達(dá)變化;用ELISA法檢測(cè)各組細(xì)胞上清液中不同時(shí)間點(diǎn)(6h,24h,48h,72h)NGF、IL-6的含量。結(jié)果:活化組與對(duì)照組比較,細(xì)胞胞體變大,GFAP熒光增強(qiáng);RT-PCR示GFAP mRNA、NGF mRNA、IL-6 mRNA表達(dá)均明顯增高,與對(duì)照組比較差異有顯著性(P<0.01);ELISA法檢測(cè)示星形膠質(zhì)細(xì)胞活化后NGF分泌量在活化后24小時(shí)達(dá)到高峰,與對(duì)照組比較差異有顯著性(P<0.01);活化后48小時(shí)IL-6的含量達(dá)到高峰,與對(duì)照組比較差異有顯著性...
