Abstract: Provided herein are HIV vaccines that encompasses recombinant trimers that mimic native HIV-1 envelope trimers. Also provided are methods of administering to a subject in need thereof an HIV vaccine provided herein to elicit antibodies against a recombinant trimer in the subject. A recombinant trimer is formed by a recombinant protein comprising a recombinant HIV-1 gp140 fused to a tag through a linker at C-terminus of the recombinant HIV-1 gp140, wherein the linker is sufficiently long so that the tag is accessible for binding by a binding molecule bound on a solid matrix during purification of the recombinant trimer.

Abstract: An approach of producing recombinant trimers that mimic native HIV-1 envelope trimers is developed. A recombinant protein forming the recombinant trimers encompasses a recombinant HIV-1 gp140 fused to a tag through a linker at C-terminus of the recombinant HIV-1 gp140. The linker is sufficiently long so that the tag is accessible for binding by a binding molecule bound on a solid matrix. After expressed in a cell, the recombinant protein is secreted into the culture medium and assembles into recombinant trimers therein. The recombinant trimers may be directly purified from the culture medium. Cleaved and uncleaved trimers from different clade viruses are produced.

Abstract translation: 开发了生产模仿天然HIV-1包膜三聚体的重组三聚体的方法。 形成重组三聚体的重组蛋白包含通过重组HIV-1 gp140的C-末端的接头与标签融合的重组HIV-1 gp140。 接头足够长，使得标签可通过结合在固体基质上的结合分子进行结合。 在细胞中表达后，将重组蛋白分泌到培养基中并在其中组装成重组三聚体。 重组三聚体可以从培养基中直接纯化。 产生来自不同进化枝病毒的切割和未切割的三聚体。
