Abstract
Recombinant expression vectors and methods are provided for detecting HIV and monitoring HIV drug resistance. The method comprises: taking a culture of cells; adding a recombinant viral vector into the culture to transduce the cells, the recombinant viral vector comprising a reporter sequence 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 a cell in the culture that is transduced by the recombinant viral vector, and a receptor sequence comprising CD 4 and one or more coreceptor genes, expression of the coreceptor genes facilitating productive infection of the transduced cell and enabling HIV virus which has infected the transduced cell to replicate and infect non-infected cells in the culture of the cells transduced by the recombinant viral vector; infecting the transduced cells with a sample containing HIV; adding one or more anti-HIV agents to the cell culture; and detecting a change in a level of expression of the reporter gene in cells.
