近期,Nature Communications 在线发表了中山大学生命科学学院徐安龙教授课题组的研究论文“The Role of Alternative Polyadenylation in the Antiviral Innate Immune Response”。该论文对病毒感染后,全基因组水平可选择性多聚腺苷酸化(Alternative Polyadenylation,APA)的现象进行研究,发现APA在抗病毒天然免疫中扮演了重要角色。徐安龙教授为论文通讯作者,贾鑫博士、元少春教授和王遥博士为论文第一作者。

近年来,从对单个抗病毒免疫基因的功能研究到病毒感染后的转录组学、蛋白质组学、代谢组学和脂类组学,均取得了一定的研究成果。而APA作为近年来提出的转录后基因表达调控的新机制在抗病毒免疫过程中的作用及调控机制的研究近乎空白。为填补这一空白并发现抗病毒免疫调控的新机制,该论文利用徐安龙教授团队自主创新的,用于全基因组APA位点扫描的IVT-SAPAS技术,对RNA病毒感染免疫细胞后的不同时间点进行了全基因组APA位点扫描,发现全基因组水平平均tandem 3’UTR长度随着病毒的感染而逐渐缩短,大量抗病毒免疫信号通路相关基因在病毒感染后发生APA。通过敲低核心3’ 加工因子,发现当全基因组水平poly(A) 位点的使用受到影响后,病毒复制也受到显着影响,揭示了APA在抗病毒免疫中的重要调节作用。

NEJM:抗病毒治疗可防止肝移植导致的丙肝病毒再感染

2017年1月13日讯 /生物谷BIOON /——根据一项西北医学院的2期临床试验,感染丙肝病毒的病人如果在进行肝移植时进行抗病毒药物治疗,那么产生持久的抗病毒反应的几率很高。医学部胃肠病学和肝脏病学教授Josh Levitsky博士在国际顶级医学期刊《New England Journal of Medicine》上发表了这项最新研究成果,揭示了一种可能防止这些病人再次感染的有效途径

Plos one:艾滋病治疗现状:2005-2015年缅甸地区大数据分析

近年来,使用抗逆转录病毒治疗(ART)艾滋病毒感染者的人数迅速增加。近期,一项发表在Plos one杂志上的研究旨在估计缅甸综合艾滋病关怀计划(IHC)中,一线抗病毒治疗的病毒学失败率以及转为二线抗逆转录病毒治疗的比率。此研究回顾性分析了2005年至2015年间,收集了在IHC中开始使用一线抗逆转录病毒治疗的所有青少年和成人HIV感染者的常规数据。评估了一线抗病毒治疗的病毒学失败和转为二线抗病毒治

HEPATOLOGY:肝移植等待名单上的丙肝患者,抗病毒治疗的更佳时机在何时?

直接经口服的抗病毒药物已经改变了丙肝患者肝移植前和肝移植后的治疗范式。在丙肝患者移植前和移植后的治疗上,就直观上来讲,抗病毒治疗也许提高了肝功能但部分降低了施行肝移植的必要性。麻省总医院的一个研究小组的目标是在MELD评分基础上筛选出合适的失代偿肝硬化患者,这些患者将能从移植前治疗中获益(或者不获益)。
