应用

人白介素2已用于评估肿瘤坏死因子受体1(TNFR1)的变化。它也已用于Tregs上的TNFR2表达。[1]

生化/生理作用

白介素2(IL2)是一种促炎性细胞因子。[2]它由三个亚基组成,其中β亚基对于受体介导的信号传导很重要。[3]IL2增强T调节细胞[4]的发育,并在抗肿瘤免疫中起关键作用。[2]
白细胞介素-2(IL-2)是由某些T淋巴细胞亚群产生的免疫调节因子。该淋巴因子能够促进活化T细胞和相关细胞类型的长期生长。IL-2在NK细胞的激活和增殖、诱导γ-干扰素和B细胞生长因子分泌中发挥作用,并且能够调节IL-2受体的表达。

外形

从50 mM磷酸钠缓冲盐水(pH值7.0)中的0.2 μm过滤溶液中冻干,每0.1 mL细胞因子含有0.1%人血清白蛋白。

分析说明

在使用IL-2依赖性鼠细胞毒性T细胞系CTLL-2的细胞增殖测定中测试生物活性。
