神经胶质细胞系衍生的神经营养因子

概述

胶质细胞系来源的神经营养因子(GDNF)是一种神经营养因子,是肿瘤生长因子(TGF)- β超家族的成员。GDNF家族的生长因子还包括neurturin、persephin和artemin,它们有七个保守的半胱氨酸残基,称为半胱氨酸结(Treanor et al.)。GDNF家族配体通过结合特异性GDNF家族受体-α (GFRα)共受体发出信号,激活RET受体酪氨酸激酶(Durbec等)。四种不同形式的GFRα共受体已被表征(GFRα 1-4);GDNF在与RET形成复合物之前特异性结合GFRα1 (Airaksinen & Saarma)。在体内和体外研究中,已知GDNF可促进中脑多巴胺能神经元的存活和形态分化,并增加其高亲和力多巴胺摄取(Granholm等;Lin等人)。GDNF也被证明在对退行性毒素的反应中对死亡的多巴胺能神经元具有恢复作用(Aoi等人)。GDNF与人重组BDNF(脑源性神经营养因子;目录#78005),BrainPhys™Neuronal Medium(目录#05790)和其他补充剂可用于将人类多能干细胞(hPSC)衍生的神经祖细胞分化为神经元(Bardy等人)。

Data Figures

(A) The biological activity of Human Recombinant GDNF was tested by its ability to promote the proliferation of C6 cells. Cell proliferation was measured after 7 days of culture using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum. The EC50 in the example above is 2.17 μg/mL. (B) 1 μg of Human Recombinant GDNF was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Human Recombinant GDNF is a homodimer of 15.2 kDa subunits with a predicted total molecular mass of 30.4 kDa.
