摘要 共济失调毛细血管扩张突变基因(ataxia telangiectasia-mutated gene,ATM)是和DNA损伤有关的一个重要基因。与ATM相关的T淋巴细胞衰老在慢性病毒感染过程中的作用及其机制受到重视。研究表明,减数分裂重组蛋白11(recombinant meiotic recombination,MRE11)/RAD50/NBS1(MRN)复合物-ATM相关通路在丙型肝炎病毒(hepatitis C virus,HCV)感染后被抑制,导致T淋巴细胞的功能障碍、衰减并可能介导HCV感染的致癌性和免疫逃逸;此外,该通路直接参与并协助人类免疫缺陷病毒(human immunodeficiency virus,HIV)和人乳头瘤病毒的感染与复制。本文主要讨论MRN-ATM相关通路分别在HCV、HIV和人乳头瘤病毒感染过程中的作用,为研发新的相关抗病毒及免疫联合治疗药物提供思路。
