肿瘤坏死因子α
肿瘤坏死因子-α (TNF-α)是一种促炎细胞因子,可激活NF-κB、MAPK和PI3K/AKT通路。炎症和感染条件下,活化的T细胞和巨噬细胞是TNF-α的主要产生者。许多其他类型的细胞已被证明产生TNF-α,其中包括B细胞、NK细胞、肥大细胞、中性粒细胞、树突状细胞、小胶质细胞、内皮细胞、平滑肌细胞、心肌细胞和成纤维细胞。TNF-α对癌细胞具有细胞毒作用,其机制是通过激发抗肿瘤的免疫抑制反应。TNF-α刺激E-和p -选择素的表达,从而促进中性粒细胞、单核细胞和记忆T细胞粘附于活化的血小板和内皮细胞(zelov<e:1> & Hošek)。TNF-α的其他作用包括血管扩张和水肿形成。体外研究表明,在成年大鼠的神经前体细胞(NPCs)中,TNF-α可抑制源自齿状回的NPCs的神经发生,并促进源自脑室下区的NPCs向星形胶质细胞形成(Borsini等人)。

(A) The biological activity of Rat Recombinant TNF-alpha was tested by its ability to inhibit cell growth of mouse L929 cells. Cell viability 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 above example is less than 0.05 ng/mL. (B) 2 μg of Rat Recombinant TNF-alpha was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining.
