摘要
干扰素(Interferon,IFN)作用于靶细胞表面受体后,通过一系列信号传导激活干扰素刺激基因(Interferon stimulated genes,ISGs)的表达。干扰素刺激基因及其表达产物具有抗病毒、免疫调控等多种生物学功能,是干扰素发挥功能的重要效应分子,同时具有潜在的临床意义。众多国内外研究发现ISGs对Ⅰ型干扰素临床抗病毒效果具有预测意义,同时可能成为某些自身免疫疾病临床诊断的新靶标以及作为一些肿瘤治疗药物新靶点等潜在应用价值。本文将从干扰素刺激基因的诱导产生、抗病毒等生物学功能以及潜在临床意义方面展开综述。
Interferon(IFN) acts on the surface of the target cell receptors and activate the expression of interferon stimulated genes( interferon stimulated genes,ISGs) through a series of signal transduction. ISGs have antiviral and immunomodulation and other biological functions,indicating ISGs are important molecules for interferon to function and have some potential clinical significance. A large number of research results showed that ISGs may predict the antiviral effect of IFN-α;specific expression of ISGs in patients with autoimmune diseases in vivo may be used as a new biomarker for clinical diagnosis of the diseases;ISGs may act as a new target for cancer treatment and have other potential applications. This review mainly focuses on the induction,the biological functions like antiviral effects and the potential clinical significance of ISGs.
