构建特定的微环境,协调多种免疫活性细胞的功能,是保证免疫反应正常进行的关键。人们试图通过体外重建这种微环境以及分析受这种微环境调控的转录因子及其网络来阐明这种免疫反应的分子机制。建立了一个非常有效地诱导类向IgA转换的体外培养体系。研究发现,Runx转录因子是IgA类转换所必需的,它们作用于维甲酸转化生长因子-β1信号的下游,而Runx3对调节性T细胞的分化和成熟是必不可少的。
英文摘要
It is essential for proper for proper progression of immune reaction that construction of specific microenvironment and harmonized function of a variety of immuno-competent cells. It is tried to elucidate molecular mechanisms of such immune reaction by reconstruction of such microenvironment in vitro and analyses of transcription factors and their networks regulated by such microenvironment.An in vitro culture system that very efficiently induces class switching to IgA was established. It was found that Runx transcription factors are essential for IgA class switching and they act downstream of signals from retinoic acid TGF-beta1, and that Runx3 is essential for differentiation and maturation of regulatory T cells.
