    • Human immunodeficiency virus (HIV)-1, HIV-2, and simian immunodeficiency virus contain, in addition to the canonical gag/pol/env genes, additional small open reading frames encoding gene products, including the 96-amino acid 15-kDa virion associated HIV-1 Vpr gene product. The conservation of the vpr open reading frame in primate lentiviruses suggests that vpr is critical to viral replication. A biologically active recombinant HIV-1 Vpr protein was employed as a ligand to identify its cellular targets. A novel 41-kDa cytosolic protein was identified and termed the viral protein R interacting protein, or Rip-1. Rip-1 displays a wide tissue distribution, including relevant targets of HIV infection. Vpr protein induced nuclear translocation of Rip-1, as did glucocorticoid receptor (GR)-II-stimulating steroids. Vpr and Rip-1 coimmunoprecipitated with the human GR as part of a receptor complex. The present invention discloses methods for the identification of compounds capable of inducing GR-II/Rip-1 receptor complex cytosolic to nuclear translocation.
    • 除了典型的gag / pol / env基因之外,人类免疫缺陷病毒(HIV)-1,HIV-2和猿猴免疫缺陷病毒还包含编码基因产物的其他小型开放阅读框,包括96-氨基酸15-kDa病毒粒子 相关的HIV-1 Vpr基因产物。 灵长类动物慢病毒的vpr开放阅读框的保护表明vpr对于病毒复制至关重要。 使用生物活性的重组HIV-1 Vpr蛋白作为配体来鉴定其细胞靶标。 鉴定了一种新型的41-kDa胞质蛋白,称为病毒蛋白R相互作用蛋白或Rip-1。 Rip-1显示广泛的组织分布,包括HIV感染的相关目标。 Vpr蛋白诱导Rip-1的核易位,糖皮质激素受体(GR)-II刺激类固醇也是如此。 Vpr和Rip-1与作为受体复合物的一部分的人GR共免疫沉淀。 本发明公开了鉴定能够诱导细胞核移位的GR-II / Rip-1受体复合物的化合物的方法。

    • A method for treating an individual exposed to or infected with HIV is disclosed which comprises administering to said individual a therapeutically effective amount of one or more compounds which inhibit or prevent replication of said HIV by interfering with the replicative or other essential functions of Vpr expressed by said HIV, by interactively blocking the Vpr target in human cells, and thereby preventing translocation of the Vpr/target complex from the cytosol of said human cells to the nuclei of said cells, where Vpr carries on activities essential to replication of HIV. In preferred embodiments, the compound or compounds which interactively block the target are steroid hormone receptor antagonists, glucocorticoid receptor antagonists, or glucocorticoid receptor Type II antagonists, especially mifepristone (RU-486). Pharmaceutical compositions comprising these compounds, as well as a method for identifying them and a kit for use therein, are also disclosed.
