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:
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:
The present disclosure relates to a system for and a method of incorporating SARS-CoV-2 genes and proteins into T4 phages. The present disclosure also relates to vaccine against SARS-CoV-2 containing recombinant T4 phages created using the method provided in the present disclosure.
Abstract:
Described is an “artificial virus” (AV) programmed with biomolecules that can enter human cells and carry out precise human genome modification. The AVs comprise: at least one viral vector, such as bacteriophage T4; at least one therapeutic molecule, such as DNA, RNA, protein and their complex; and a lipid coating. Also described is a method of human genome modification, using such an AV, and a method of program such an AV.

Abstract:
Described herein is a soluble HIV-1 retrovirus transmembrane glycoprotein gp41 trimer (Soc-gp41M-Fd) containing a partial ectodomain and the cytoplasmic domain, that is fused to the small outer capsid (Soc) protein of bacteriophage T4 and the Foldon domain of the bacteriophage T4 fibritin (Fd). The gp41 trimer that has a prehairpin structure could be utilized to understand the mechanism of viral entry and as a candidate for development of HIV-1 vaccines, diagnostics and therapeutics. Other secondary embodiments of the gp41 proteins containing different modifications are also disclosed. According to one embodiment, the gp41 trimer is further attached to a cell penetration peptide (CPP). Methods of producing gp41 trimers are also disclosed.
