骨髓基质细胞抗原 2 (BST-2) 抑制 HIV-1 和其他包膜病毒从细胞表面释放。 HIV-1 Vpu 通过两种蛋白质的跨膜结构域 (TMD) 之间的相互作用与 BST-2 结合,并诱导细胞表面 BST-2 的下调,从而抵消其抗病毒活性。在本研究中,我们设计并制备了修饰肽BST2-TM-P1,其中包含BST-2 TMD的序列,保持其与BST-2竞争与Vpu结合的特性。生物学检测结果表明,BST2-TM-P1能够以Vpu依赖性方式增加细胞表面的BST-2水平,并显着抑制HIV-1病毒粒子的复制。我们的研究表明,阻断 Vpu 和 BST-2 的相互作用是对抗 HIV-1 感染的有效方法。 (C) 2014 年 Wiley 期刊公司。
Bone marrow stromal cell antigen 2 (BST-2) inhibits the release of HIV-1 and other enveloped viruses from the cell surface. HIV-1 Vpu binds to BST-2 through an interaction between transmembrane domains (TMD) of the two proteins and induces the downregulation of cell surface BST-2, thereby counteracting its antiviral activity. In this study, we designed and prepared a modified peptide BST2-TM-P1, which include the sequence of BST-2 TMD, keeping its property competing with BST-2 to bind with Vpu. Biological assay results indicate BST2-TM-P1 could increase the BST-2 level at the cell surface in Vpu dependent manner and significantly inhibit the replication of HIV-1 virion. Our studies indicate that blocking the interaction of Vpu and BST-2 is an effective way to combat HIV-1 infection. (C) 2014 Wiley Periodicals, Inc.
