T细胞的增殖和存活受细胞因子受体共有的γ链(γc)相关细胞因子白细胞介素 - 2(IL - 2)、白细胞介素 - 7(IL - 7)和白细胞介素 - 15(IL - 15)的调节,而另一种与γc相关的细胞因子白细胞介素 - 4(IL - 4)被认为主要影响T细胞的质量而非数量。相比之下,我们的实验表明,内源性产生的IL - 4在抗原和病原体诱导的CD8⁺T细胞应答中是CD8⁺T细胞增殖的直接、非冗余且强效的刺激因子。在BALB/c和C57BL/6小鼠中均观察到IL - 4的这些刺激作用,并且它能激活初始以及记忆/活化表型的CD8⁺T细胞,尽管对初始细胞的刺激作用弱于对后者的刺激作用。IL - 4的作用不依赖于IL - 7和IL - 15,但主要组织相容性复合体(MHC)I类分子依赖性刺激似乎是IL - 4对初始表型CD8⁺T细胞产生促有丝分裂作用所必需的。因此,内源性产生的IL - 4是T细胞免疫在数量和质量方面的重要调节因子。
T cell proliferation and survival are regulated by the cytokine receptor common γ chain (γc)3-associated cytokines IL-2, IL-7 and IL-15 while IL-4, another γc-associated cytokine, is thought to primarily affect T cell quality rather than quantity. In contrast, our experiments reveal that endogenously produced IL-4 is a direct, non-redundant and potent stimulator of CD8+ T cell proliferation in antigen- and pathogen-induced CD8+ T cell responses. These stimulatory effects of IL-4 are observed in both BALB/c and C57BL/6 mice and activate both naïve and memory/activated phenotype CD8+ T cells, although the former are stimulated less than the latter. IL-4 effects are IL-7- and IL-15-independent, but MHC class I-dependent stimulation appears to be required for the mitogenic effect of IL-4 on naïve phenotype CD8+ T cells. Thus, endogenously produced IL-4 is an important regulator of quantitative as well as qualitative aspects of T cell immunity.
