T helper (Th) cells are crucial for the development of immunity to infections and inflammatory disease. The acquisition of specific cytokine-secreting profiles, primed by the cytokine microenvironment, is required for effector function of Th cells. The most recent addition to the growing list of effector subsets are Th9 cells that secrete IL-9. In this review, we propose a model for the transcriptional regulation of the Il9 gene in IL-9-expressing T cells and the relatedness of this subset to other Th phenotypes. We suggest that transcription factors restricted to certain Th subsets and common among several subsets might play a role in the plasticity of Th9 cells.
辅助性 T 细胞(Th)对于感染和炎症性疾病的免疫发展至关重要。Th 细胞的效应功能需要通过细胞因子微环境预先确定特定的细胞因子分泌特征。在不断增加的效应亚群中,最新增加的是分泌白细胞介素 9(IL-9)的 Th9 细胞。在这篇综述中,我们提出了一个在表达 IL-9 的 T 细胞中 Il9 基因转录调控的模型,以及该亚群与其他 Th 表型的相关性。我们认为,仅限于某些 Th 亚群的转录因子,以及在几个亚群中常见的转录因子,可能在 Th9 细胞的可塑性中发挥作用。
