Using HIV Virus to Cure Cancer
Scientists are planning to use human immunodeficiency (免疫缺陷) virus (HIV) , one of mankind's most feared viruses, as a carrier of genes which can fight cancer and a range of diseases that cannot be cured. The experts say HIV has an almost perfect ability to avoid the body's immune (免疫的)defenses, making it ideal for carrying replacement genes into patients' bodies, accordin to the Observer.
A team at the California-based Salk Institute, one of the world's leading research centers on biological sciences, has created a special new breed of HIV and has started negotiations with the U.S. Food and Drug Administration (FDA) to begin clinical gene therapy (治疗) trials this year.The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have "far wider applications".
The new plan remains very likely to cause controversy since it involves making use of a virus which has caused more than 22 million deaths around the world in the past two decades. Verma said that the idea of using HIV for a beneficial purpose was "shocking" but it is possibly used to cure cancers by having all six of the potentially deadly genes removed.
Illnesses such as various cancers are caused when a gene in a patient's body fails to work properly. In the past two years, breakthroughs in genetics (遗传学) have led gene therapy scientists to try and replace the genes that do not function normally.
Unfortunately, the body's immune defenses have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carder.
The HIV virus has the ability to escape from, and then destroy the immune defense cells designed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients' bodies.
Scientists think HIV is useful because its ability to carry replacement genes into patients' bodies.()
选项
A.Right
B.Wrong
C.Not mentioned
答案
A
解析
题干:科学家认为HIV有用是因为其能携带替换基因进入病人身体。利用题干关键词scientist和carry replacement gene可以定位到第一段“The experts say HIV has an almos perfect ability to avoid the body’S ilTllTlune defenses,making it ideal for carrying replacemen genes into patients,bodies”,意为“专家说HIV有几乎完美的能力来躲过身体的免疫防御,这使得它成为携带替换基因进入病人身体的理想携带者”。由此可知,题干信息与原文信息一致,所以答案为A。
