美国科学家截止到2010年7月发现了三种强力抗体,其中最强的可以使91%的艾滋病病毒(HIV)毒株失活,比目前为止发现的任何艾滋病(AIDS)抗体都要有效,进而朝着研制AIDS疫苗的方向上迈出了重要一步。在对最强的抗体进行了细致的研究之后,科学家们详细说明了抗体作用于病毒的确切部位以及作用机理。这三种抗体是在一名60岁美国黑人同性恋男子的细胞中发现的。此人的身体可以自然地产生这种抗体。研究人员对他体内的2500万个细胞进行了筛查,发现有12个细胞可以产生上述抗体。现在科学家所面临的问题是,研制出一种疫苗或找到其他方法,让每个人的身体都可以产生这种抗体。据联合国(United Nations)估计,截至2008年底,有3300多万人感染了HIV, As of July 2010, U.S. scientists discovered three potent antibodies, the strongest of which were to inactivate 91% of the HIV strains and more effective than any AIDS antibody found so far An important step toward developing AIDS vaccine. After a detailed study of the strongest antibodies, the scientists detailed the exact role of the antibody in the virus and its mechanism of action. The three antibodies were found in cells of a 60-year-old black gay man in the United States. This human body can naturally produce this antibody. Researchers screened 25 million cells in his body and found that 12 cells produced the antibodies. Now scientists are facing the problem is to develop a vaccine or find other ways for everyone’s body can produce this antibody. According to the United Nations estimates, as of the end of 2008, more than 33 million people were infected with HIV,
