    • A method is provided for detecting a presence of HIV virus in a sample comprising: taking a culture of recombinant cells which (a) are capable of cell division, (b) express CD4 receptor and one or more additional cell surface receptors necessary to allow the HIV virus to infect, (c) enable the HIV virus to replicate and infect the noninfected cells in the cell culture, and (d) comprise a reporter sequence introduced into the recombinant cells comprising a reporter gene whose expression is regulated by a protein specific to HIV viruses which is expressed from a genome of an HIV virus upon infection of the recombinant cell by the HIV virus; contacting the cell culture with a sample to be analyzed for the presence of HIV virus in the sample; and detecting a change in a level of expression of the reporter gene in cells in the recombinant cell culture. The method can be used to detect the presence of HIV virus in a sample, detect the presence of different strains of HIV virus in a sample, detect HIV drug resistance in a sample, determine what combination of one or more anti-HIV agents would be effective in treating a patient, and screen compositions for anti-HIV activity.
    • 提供了一种用于检测样品中HIV病毒存在的方法,其包括:获取(a)能够细胞分裂的重组细胞的培养物,(b)表达CD4受体和一种或多种另外的细胞表面受体, HIV病毒感染,(c)使HIV病毒复制并感染细胞培养物中的未感染细胞,和(d)包含引入重组细胞的报道序列,其包含报道基因,其表达受特异性蛋白质 HIV病毒在HIV病毒感染重组细胞时由HIV病毒基因组表达的HIV病毒; 使细胞培养物与待分析样品中样品中HIV病毒的存在接触; 并检测重组细胞培养物中细胞中报道基因表达水平的变化。 该方法可用于检测样品中HIV病毒的存在,检测样品中HIV病毒的不同菌株的存在,检测样品中的HIV耐药性,确定一种或多种抗HIV药物的组合将是 有效治疗患者,筛选组合物用于抗HIV活性。
