转化生长因子(TGF)-β1是一种重要的多能细胞因子,具有明显的免疫抑制作用,缺乏TGF -β1可导致小鼠致死性自身免疫。然而,其免疫抑制作用的机制尚不完全清楚。在这里,我们报道TGF-β1支持外周CD4+CD25+调节性T (T reg)细胞中Foxp3表达、调控功能和稳态的维持,但不是胸腺发育所必需的。我们发现在8 - 10 d龄TGF-β1缺陷小鼠中,外周T细胞数量明显减少,而胸腺T细胞数量不明显减少。此外,我们的实验表明,T细胞中TGF-β介导的信号传导缺陷与Foxp3表达和抑制活性的降低有关。因此,我们的研究结果建立了外周T细胞TGF-β1信号传导与体内T细胞维持之间的重要联系。
Transforming growth factor (TGF)-β1 is a major pluripotential cytokine with a pronounced immunosuppressive effect and its deficiency results in lethal autoimmunity in mice. However, mechanisms of its immunosuppressive action are not completely understood. Here, we report that TGF-β1 supports the maintenance of Foxp3 expression, regulatory function, and homeostasis in peripheral CD4+CD25+ regulatory T (T reg) cells, but is not required for their thymic development. We found that in 8–10-d-old TGF-β1–deficient mice, peripheral, but not thymic, T reg cells are significantly reduced in numbers. Moreover, our experiments suggest that a defect in TGF-β–mediated signaling in T reg cells is associated with a decrease in Foxp3 expression and suppressor activity. Thus, our results establish an essential link between TGF-β1 signaling in peripheral T reg cells and T reg cell maintenance in vivo.
