The Ca++-regulated calcineurin/NFAT cascade is one of the crucial signalling pathways that controls adaptive immunity. However, a number of novel experimental data suggest that, in addition to their role in T cell activation, NFATc transcription factors play also a decisive role in the generation of peripheral tolerance against self-antigens. This function of NFATc factors is mediated by controlling activation-induced cell death and clonal anergy of T helper cells and the activity of regulatory T cells. The multi-functional role of NFATc proteins characterize these transcription factors as key regulators of immunological tolerance and, if dysregulated, of development of autoimmune diseases.
钙离子调节的钙调神经磷酸酶/活化T细胞核因子(Ca++-regulated calcineurin/NFAT)级联反应是控制适应性免疫的关键信号通路之一。然而,大量新的实验数据表明,除了在T细胞活化中发挥作用外,NFATc转录因子在对外源自身抗原产生外周耐受方面也起着决定性作用。NFATc因子的这一功能是通过控制辅助性T细胞的活化诱导细胞死亡和克隆无能以及调节性T细胞的活性来介导的。NFATc蛋白的多功能作用将这些转录因子表征为免疫耐受的关键调节因子,若其失调,则会导致自身免疫性疾病的发生。
