生化机理
白细胞介素-2(IL-2)是一种 O 型糖基化的四α-螺旋束细胞因子,对抗原激活的 T 细胞具有强大的刺激活性。它由 CD4+ 和 CD8+ T 细胞、γ δ T 细胞、B 细胞、树突状细胞和嗜酸性粒细胞表达。成熟的小鼠 IL-2 与人类和大鼠 IL-2 分别有 56% 和 73% 的 aa 序列相同性。它的 N 端区域包含一个多谷氨酰胺伸展区,显示出菌株特异性的异质性。小鼠和人类 IL-2 具有跨物种活性。IL-2 的受体由三个亚基组成,它们以不同的预形成复合物存在于细胞表面。55 kDa IL-2 R alpha 对 IL-2 具有特异性,结合亲和力低。75 kDa 的 IL-2 R beta 也是 IL-15 受体的一个组成部分,它与 IL-2 的结合具有中等亲和力。与 IL-4、-7、-9、-15 和-21 的受体共有的 64 kDa 普通γ链γc/IL-2 R gamma 与 IL-2 没有独立的相互作用。与配体结合后,信号转导由 IL-2 R beta 和 gamma c 共同完成。它能促使静止的 T 细胞增殖,并诱导 IL-2 和 IL-2 R alpha 的合成。它能促进 Fas 诱导的幼稚 CD4+ T 细胞的死亡,但不能促进活化的 CD4+ 记忆淋巴细胞的死亡,从而促进 T 细胞的平衡。IL-2 在调节性 T 细胞的扩增和维持中发挥着核心作用,但它会抑制 Th17 极化细胞的发育。因此,IL-2 可能是自然抑制自身免疫的关键细胞因子。
生物活性
1. Measured in a cell proliferation assay using mouse splenocytes. The ED50 for this effect is typically 11.12 ng/mL. 2. Immobilized Recombinant Mouse IL-2 Protein (rp170395) at 1.0 μg/mL can bind IL-2 Rat mAb (Ab110078) with the EC50 of 230.4 ng/mL.
