纤毛神经营养因子
睫状体神经营养因子(CNTF)是一种属于四螺旋束细胞因子家族的神经营养因子,在结构上与白细胞介素6 (IL-6)、白细胞介素11 (IL-11)、白血病抑制因子(LIF)和肿瘤抑制素M (OSM)相关。CNTF与其受体CNFTRα结合,诱导形成信号转导IL-6受体gp130和LIF受体(LIFR)-β的异源二聚体,从而触发JAK/STAT、ERK和PI3K信号级联反应(Schuster等)。CNTF在神经发生和神经干细胞分化中发挥重要作用,并被认为在治疗神经系统疾病中具有治疗作用(Ding等;奥本海姆等人)。CNTF还被证明可以保护杆状光感受器免受光诱导的损伤,并对由遗传缺陷或毒素、自身抗体或强光引起的损伤引起的视网膜退行性疾病具有治疗作用(Pernet等人;Rhee等人)。CNTF的另一个治疗作用是保护少突胶质细胞免于凋亡诱导的死亡(Louis等人)。此外,CNTF通常用于将人类多能干细胞(hPSC)衍生的神经祖细胞分化为星形胶质细胞(Krencik & Zhang)。

(A) The biological activity of Human Recombinant CNTF was tested by its ability to promote the proliferation of TF-1 cells. Cell proliferation was measured 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 less than 200 ng/mL.
(B) 2 μg of Human Recombinant CNTF was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Human Recombinant CNTF has a predicted molecular mass of 22.8 kDa.
