系统性红斑狼疮(SLE)是复杂自身免疫性疾病的原型。研究表明,遗传,激素和环境因素有助于疾病的发展。有趣的是,最近几项涉及SLE患者和该疾病小鼠模型的研究表明,干扰素(IFN)刺激基因(ISG)在SLE的发展中发挥作用。ISG的一个家族是Ifi 200家族,其包括小鼠(Ifi 202 a、Ifi 202 b、Ifi 203、Ifi 204和Ifi 205)和人(IFI 16、MNDA、AIM 2和IFIX)基因。小鼠基因簇在1号染色体上的血清淀粉样蛋白P组分(Apcs)和α-血影蛋白(Spna-1)基因之间,而人类基因簇在同线区1 q23。Ifi 200家族基因编码结构和功能相关的蛋白质(p200家族蛋白质)。细胞中某些p200家族蛋白表达的增加与细胞增殖的抑制、细胞凋亡的调节和细胞分化有关。我们的研究涉及B6.Nba2同源小鼠的产生,再加上基因表达分析,确定了Ifi 202作为一个候选的狼疮易感基因。重要的是,最近使用不同的SLE小鼠模型的研究表明,免疫细胞中Ifi 202基因(编码p202蛋白)的表达增加有助于狼疮易感性。与p202蛋白在狼疮易感性中的功能作用一致,人SLE患者中IFI 16蛋白水平的增加与疾病相关。本文就p200家族蛋白在SLE发生发展中的调控和作用作一综述。
Systemic lupus erythematosus (SLE) is the prototype of complex autoimmune diseases. Studies have suggested that genetic, hormonal, and environmental factors contribute to the development of the disease. Interestingly, several recent studies involving SLE patients and mouse models of the disease have suggested a role for interferon (IFN)-stimulated genes (ISGs) in the development of SLE. One family of ISGs is the Ifi200-family, which includes mouse (Ifi202a, Ifi202b, Ifi203, Ifi204, and Ifi205) and human (IFI16, MNDA, AIM2, and IFIX) genes. The mouse genes cluster between serum amyloid P-component (Apcs) and α-spectrin (Spna-1) genes on chromosome 1 and the human genes cluster in syntenic region 1q23. The Ifi200-family genes encode structurally and functionally-related proteins (the p200-family proteins). Increased expression of certain p200-family proteins in cells is associated with inhibition of cell proliferation, modulation of apoptosis, and cell differentiation. Our studies involving generation of B6.Nba2 congenic mice, coupled with gene expression analyses, identified the Ifi202 as a candidate lupus-susceptibility gene. Importantly, recent studies using different mouse models of SLE have suggested that increased expression of Ifi202 gene (encoding p202 protein) in immune cells contributes to lupus susceptibility. Consistent with a functional role for the p202 protein in lupus susceptibility, increased levels of IFI16 protein in human SLE patients are associated with the diseases. This review summarizes recent findings concerning the regulation and role of p200-family proteins in the development of SLE.
