摘要
Interleukin(IL)-28B(interferon lambda3,IFN-λ3)是一类属于IFN-λ家族的新型白介素,编码基因位于19号染色体上.近期的多项研究阐述了IL-28B的基因多态性(single nucleotide polymorphisms,SNPs)在丙型肝炎病毒(hepatitis C virus,HCV)感染者治疗上的重要性,并成功的定位了两个关联性最强的SNPs:rs12979860-IL-28B上游3kb处,rs8099917-IL-28B上游8kb处.IL-28B的基因多态性具有很好的临床应用前景,根据其基因型可以预测患者的自愈率,以及对聚乙二醇干扰素-α(PEG-IFN-α)和利巴韦林(ribavirin,RBV)联合治疗的持续应答率,从而有助于确定HCV感染者的个性化治疗方案.
The interleukin(IL)-28B gene is located on the chromosome 19 and encodes a new member(interferon-lambda 3,IFN-λ3) of the interferon family.Recently,published data show that single nucleotide polymorphisms(SNPs) near the IL28B gene could be used to predict response to treatment of hepatitis C virus infection.Two SNPs,rs12980275(3 kb downstream of the IL28B gene) and rs8099917(8 kb upstream),were the strongest association sites among all the identified SNPs.The SNPs of the IL-28B gene show a good potential for clinical application.The spontaneous recovery rate of HCV infection,and the sustained virological response(SVR) to the combination therapy with pegylated IFN(PEG-IFN)-α and ribavirin(RBV) could be predicted according to the SNPs of IL-28B,which will be helpful for personalized therapy of HCV infection.
