干扰素-γ
干扰素-γ (IFN-γ),也称为 II 型干扰素,由 T 细胞和 NK 细胞产生,树突状细胞和巨噬细胞也产生少量干扰素。IFN-γ 受感染后分泌的细胞因子例如 IL-12 和 IL-18控制(Schroder et al.)。IFN-γ 与受体复合物结合,并通过 JAK/STAT 通路启动信号转导;最终导致许多基因的转录和激活,这些基因控制着多种免疫功能(de Weerd & Nguyen; Krause et al.)。IFN-γ 通过促进微生物效应功能的激活,例如活性氧、一氧化氮和补体的产生(Schroder et al.),刺激巨噬细胞、NK 细胞和中性粒细胞的抗菌和抗肿瘤活性(Billiau & Matthys)。 IFN-γ 可增强树突状细胞和单核吞噬细胞中 MHC I 类和 II 类分子的表达,并促进树突状细胞产生 IL-12。在 B 细胞中,IFN-γ 可刺激小鼠和人细胞的存活和生长,并使 B 细胞从增殖转向分化。IFN-γ 有利于 Th1 细胞而非 Th2 细胞的发育,并刺激单核细胞分化和功能(Schroder et al.)。

(A) The biological activity of Human Recombinant IFN-gamma was tested by its ability to promote the cytotoxicity of HT-29 (HTB-38) cells. Cytotoxicity was measured using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell death is at 50% of maximum. The EC50 for this effect is 0.035 ng/mL.
(B) 2 μg of Human Recombinant IFN-gamma was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Human Recombinant IFN-gamma has a predicted molecular mass of 17 kDa.
