Rapid formation of human immunodeficiency virus-like particles

Transient expression of virus-like particles in plants: a promising platform for rapid vaccine production

Transient expression is an efficient and fast system to express recombinant proteins which has been used in different eukaryotic hosts such as mammalian and plant cells. Several applications of this system have so far been used which expression of proteins of interest is one of them. Recently, plants have attracted attention for being used as hosts for the production of recombinant pharmaceutic...

Incorporation of human immunodeficiency virus type 1 reverse transcriptase into virus-like particles.

We demonstrate that a genetically engineered human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) composed mainly of p66 or p51 subunits can be incorporated into virus-like particles (VLPs) when coexpressed with HIV-1 Pr55(gag). VLP-associated RT exhibited a detergent-resistant association with immature cores during sucrose gradient equilibrium centrifugation, suggesting that ...

Human Immunodeficiency Virus (HIV) and Coronary Atherosclerotic Plaque Formation: A Review

Human immunodeficiency virus-like particles produced by a vaccinia virus expression vector.

Infectious retrovirus particles consist of a core structure containing RNA and gag-pol polypeptides surrounded by a lipid membrane studded with env proteins. A recombinant vaccinia virus was designed to express the entire gag-pol precursor protein of the human immunodeficiency virus type 1. Synthesis and processing of gag proteins occurred in mammalian cells infected with this live recombinant ...

Immunization with recombinant p17/p24:Ty virus-like particles in human immunodeficiency virus-infected persons.

In studies of the natural history of human immunodeficiency virus type 1 (HIV-1) infection, it has been repeatedly shown that higher-titer antibody responses to the HIV gag p24 protein correlate with less rapid disease progression. In HIV-negative persons, immunization with HIV-1 p17/p24:Ty virus-like particles (p24-VLP) induced humoral and cellular immune responses to p24. This construct was t...
