    摘要: The present invention provides mammalian cells modified to stably express at least the entire human immunodeficiency virus-1 envelope protein gp160. The invention provides a vaccine comprising the cells of the invention. The invention also provides methods for screening compounds for their ability to inhibit formation of syncytia between cells that express HIV-1 gp160 and cells that express CD4 comprising mixing cells of invention, cells that express CD4 on their surfaces, and a test compound for a length of time sufficient for syncytia to form; and then determining the amount of syncytia formation.
