| 摘 要： | 目的研究经脂多糖(LPS)刺激后神经胶质细胞培养上清对神经元死亡及凋亡的诱导情况。方法体外原代培养小鼠混合神经胶质细胞和神经元细胞,采用LPS刺激神经胶质细胞,24h后收获条件培养上清与神经元细胞共孵育,检测神经元细胞死亡和凋亡的情况。结果 LPS刺激后的神经胶质细胞培养上清对神经元的毒性作用与未刺激组无明显差别(P>0.05);LPS刺激后的神经胶质细胞条件培养上清诱导神经元细胞凋亡明显高于未刺激组(P<0.05)。结论神经胶质细胞LPS刺激后的条件培养上清可以诱导神经元凋亡,但没有导致明显的神经元细胞死亡。

| Abstract: | Objective To investigate the apoptosis and death of neuron induced by LPS-stimulated mixed glial cell culture.Methods The mixed glial cells and neurons were cultured.After treated by LPS,the supernatant of cultured mixed glial cells were added into the neurons' culture.The death and apoptosis of neurons were detected.Results Compared with the control,the neuron cells could be induced to be apoptosis by the supernatant of LPS-induced mixed glial cell culture(P<0.05),but the death of neuron cells was not so o... |
