科学家宣称：杀死艾滋病毒的干细胞确实存在
腾讯科技讯 据国外媒体报道，加州大学洛杉矶分校（UCLA）艾滋病研究所的专家们于2009年12月9日凌晨（北京时间）宣布，他们能够找到一种可以杀死艾滋病病毒的干细胞，将有效的防治艾滋病病毒。
据美国科学家家介绍，这些干细胞能够激活一种主动搜索模式，该模式可以帮助干细胞搜索并攻击所有已被艾滋病病毒感染的细胞，并且这些干细胞还拥有一些特殊的能力，可在不久的将来用于治疗慢性病毒性疾病。
国际艾滋病学会专家斯科特表示：我们已经对这一发现进行了研究，可以证明这种干细胞可以用来进行人类免疫系统工程架构。特别是对T细胞的反应能力非常突出，对艾滋病病毒具有专门的灭杀能力。而相关的研究将为人类治疗和恢复各种免疫系统病变、慢性病毒性疾病、肿瘤等奠定进一步发展的基础。
据报道，加州大学洛杉矶分校（UCLA）艾滋病研究所已在12月7日将相关数据和论文发表在该校的在线图书馆上。
杀伤性T细胞，在科学上称为CD8细胞毒性T淋巴细胞，是目前艾滋病新研究的主要目标。加州大学洛杉矶分校试图找出它们的工作原理，以及如何最好地激活杀伤性T细胞的能力。但是T细胞在人体内的数量严重不足。因此，必须在实验室中培养大量的T细胞。实际上，加大的科学家们就是用实验室培养的T细胞进行了部分激活，而被激活的T细胞首先注入人体胸腺组织，并再次植入小鼠体内进行对比。
研究人员注意到，在激活和培养T细胞的过程中形成了一种成熟的、多功能（细胞的适应性）的干细胞组织，这种干细胞是符合艾滋病毒特异性CD8细胞特性的干细胞类型。这种类型的干细胞经过检测，能够遏制艾滋病毒靶细胞的蛋白质。加州大学洛杉矶分校医学与艾滋病研究所副所长扎克·杰罗姆教授说，下一步将准备把这种类型的干细胞测试更复杂的动物模型，如灵长类动物。扎克·杰罗姆教授还表示，这种方法可以用来对付多种病毒性慢性疾病，它就像一个基因疫苗。
一位艾滋病防治分析家说，这种干细胞的发现有可能是第一次真正意义上的证明人类可以战胜艾滋病。（嘟嘟）
U.S. Scientists declared: to find the stem cells kills the HIV virus,

Scientists declared: kill the HIV virus, the existence of stem cells
Tariq foreign media reports, the University of California at Los Angeles (UCLA) AIDS Institute, the experts on December 9, 2009 am (Beijing time) announced that they could kill the AIDS virus can find a stem cell, will effectively prevention and treatment of HIV.
It is an introduction to American scientists, these stem cells can activate a pro-active search mode, which can help stem cells have been searched and an attack against all HIV-infected cells, and these stem cells also have some special capabilities, can be used in the near future the treatment of chronic viral diseases.
International AIDS Society experts, Scott, said: We have conducted a study of this discovery could prove that stem cells can be used for the human immune system engineering framework. Especially for T-cell ability to respond is very important, and the culling of HIV with specific capabilities. The related studies for the treatment and the restoration of the human immune system diseases, chronic viral diseases, cancer and other lay the basis for further development.
It is reported that the University of California at Los Angeles (UCLA) AIDS Institute, December 7 in the related data and papers published in the online library at the school.
Anti-T-cells, in science CD8 cytotoxic T lymphocytes is called, is the main objective of the new study of AIDS. University of California at Los Angeles trying to find out how they work, and how best to activate the anti-T-cells. T cells in the human body, however the number of grossly inadequate. Therefore, we must cultivate in the laboratory a large number of T cells. In fact, the increase scientists is to use laboratory-grown T-cells in some of the activated T cells were activated, first injected into the human thymus tissue, and once again implanted in mice were compared.
The researchers noted that in the cultured T-cell activation and the process of forming a mature, multi-function (cell-adaptive) stem cell tissue, such stem cells is consistent with characteristics of HIV-specific CD8 cells in the stem cell types. This type of stem cells have been tested to contain the target cells of HIV proteins. University of California at Los Angeles, deputy director of the Institute of Medicine and AIDS, said Professor 扎克杰罗姆 the next step would be prepared to test this type of stem cells in more complex animal models, such as primates.扎克杰罗姆 Professor also said that this method can be used to deal with a variety of chronic viral diseases, it's like a DNA vaccine.
An AIDS prevention and control, analysts say that the discovery of stem cells may be the first real sense that human can fight against AIDS. (Toot)
