摘要

两个极化的辅助性T细胞(Th)亚群Th1和Th2分别由它们的标志性细胞因子干扰素γ (IFN-γ)和白细胞介素4 (IL-4)鉴定。因此,了解细胞因子表达的转录调控对于阐明Th细胞分化过程至关重要。普遍存在的和组织特异性的转录因子,以及基因组位点的染色质重塑都与IL-4和IFN-γ的调节有关。我们提出了一个基于Th1-和Th2特异性转录因子之间平衡的Th1/Th2极化模型。

Transcriptional regulation of Th1/Th2 polarization

The two polarized T helper (Th) subsets Th1 and Th2 are identified by their signature cytokines, interferon γ (IFN-γ) and interleukin 4 (IL-4) respectively. Understanding the transcriptional regulation of cytokine expression is therefore critical for elucidating the process of Th cell differentiation. Ubiquitous and tissue-specific transcription factors, as well as chromatin remodeling of genomic loci have been implicated in IL-4 and IFN-γ regulation. We propose a model of Th1/Th2 polarization based on the balance between Th1- and Th2-specific transcription factors.
