2017考研英语拓展阅读：我国在根治HIV等病毒感染上取得突破
考研英语阅读能力提升需要不断地积累练习，通过阅读来积累词汇量，提升阅读速度和理解能力。暑期强化复习，阅读强度要加大，新东方在线继续分享一些有关政治、经济、文化、生活、体育、科技等方面的文章，大家要多多拓展。下面一篇文章是我国在根治HIV等病毒感染上取得突破。2017考研英语拓展阅读：我国在根治HIV等病毒感染上取得突破
Chinese scientists have defined a subset of a type of virus-specific cells
that could pave the way for new ways to treat chronic diseases like HIV/AIDS and
cancer, Xinhua News Agency reported on Saturday.
星期六，据新华社报道，中国科学家揭示了一群新的CD8+T细胞亚类，这一发现将有助于为艾滋病、癌症等慢性病毒感染的治疗提供新方法。
Nature magazine published online a research paper on Wednesday, claiming
that virus-specific cells, CD8+T, are able to control viral replication in both
animal models and HIV infections.
星期三，《自然》杂志发表了一篇研究成果，指出CD8+T细胞亚类能抑制动物模型和艾滋病感染的病毒复制。
"CD8+T cells were found to deplete during chronic viral infections in past
research but could curtail acute viral infections by secreting antiviral
cytokine that could eliminate the viruses," Ye Lilin, co-author of the paper and
professor at the Third Military Medical University, told Xinhua on Saturday.
据该研究论著的合著者、第三军医大学的叶丽林教授于星期六接受新华社采访时介绍，“此前的研究发现，在急性病毒感染中，特异性CD8+T细胞通过分泌抗病毒细胞因子，杀伤病毒感染的细胞，从而有效清除病毒;但在慢性病毒感染过程中，病毒特异性的CD8+T细胞却显出功能耗竭现象。”
However, research findings showed that a subset of CD8+T cells was largely
able to curtail viral replication in animal models and HIV infections.
然而，研究结果发现，在动物模型以及艾滋病感染中，CD8+T细胞亚类细胞仍然能在很大程度上抑制病毒的复制。
Researchers also found the subset that offers higher anti-viral potential
than previously known, showing greater therapeutic potential, Xinhua
reported.
据新华社报道，研究人员还发现，该类细胞群具备的抗病毒能力远远高出人们已知的水平，显示出很强大的治疗可能。
"Through certain means, to increase and stabilize the type of cells can
strengthen their virus-purging ability, thus providing new possibilities for
cures," Ye said.
叶教授指出：“通过一定的手段，增加和稳定这一类细胞，可以增强其清除病毒的功能，这就为治愈这些疾病提供了新的可能。”
Current therapies can only contain the viral replication, but can not purge
them completely in chronic diseases like HIV/AIDS. Chinese researchers will now
use the findings to further conduct research into immunotherapy in cancer and
HIV, Ye said. The research was led by the Third Military Medical University in
Chongqing with a number of partner institutions.
目前，治疗艾滋等慢性病毒感染导致的疾病，化学药物只能在一定程度上抑制病毒复制，尚不能彻底根除。叶教授透露，下一步，他们将沿着这一新的研究策略，把研究成果运用到癌症和艾滋的免疫治疗研究中。该研究由重庆第三军医大学主导，还有一些其他机构的参与。
