研究：艾滋病毒可入侵女性健康皮肤组织
美国研究者周二表示，艾滋病毒不是通过受损皮肤，而是通过攻击正常健康的生殖器官组织来入侵女性体内的。此研究对艾滋病的传播情况提供了新观点。
研究者称，以前的观点认为，艾滋病毒HIV是通过受损皮肤，如皰疹的伤口处，进入组织深层的免疫细胞的。甚至还有人认为，性交时，阴道的正常皮肤就能抵抗病毒的入侵。
“正常的皮肤也会受侵袭，”美国西北大学芬堡医学院的ThomasHope在接受电话采访时说，“以前人们认为皮肤必须有破口才会感染艾滋病毒。”Hope在旧金山的美国细胞生物学学会会议上发表了研究报告。
他称，目前科学家对女性通过性途径感染艾滋病的详情知之甚少。
Hope和西北大学及图兰大学的同事们采用新方法观察细胞的活动情况。他们让携带荧光跟踪物质的病毒接触那些在子宫切除手术中获取的阴道组织。
研究发现，病毒会攻击那些刚经历正常细胞脱落的皮肤，快速通过生殖器官皮肤屏障，进入免疫细胞，感染人体。
Hope表示，这说明使用疫苗和避孕套等方式来预防感染尤为重要。避孕套能有效预防艾滋病的感染。（完）
Study: HIV can be healthy female invasion of the skin
U.S. researchers said Tuesday that HIV is not damaged through the skin, but by attacking normal healthy reproductive organs of the body to the invasion of the female body. The study of the spread of AIDS to provide a new perspective.
The researchers said the former view, people living with HIV virus through the damaged skin, such as herpes wounds, deep into the organization's immune cells. Some people even believe that the sexual intercourse, the vagina of normal skin will be able to resist the invasion of the virus.
"Normal skin will be subject to attack," Northwestern University School of Medicine in Fort ThomasHope fun in a telephone interview, he said, "In the past people that will break the skin must be infected with HIV." Hope in San Francisco, United States Institute of Cell Biology Meeting, published a research report.
He said the current female scientists infected with AIDS through sexual means little is known about the details.
Hope and Northwestern University, Tulane University and colleagues used a new method to observe the activities of cells. Let them bring fluorescent material to track the virus access to those in the hysterectomy in the vaginal access to the organization.
The study found that the virus will attack those who have just gone through the normal shedding of skin cells, the rapid adoption of genital skin barrier into the immune cells infected with the human body.
Hope said that the use of vaccines and methods such as condoms to prevent infection is particularly important. Condoms to be effective in preventing HIV infection. (END)
