Stabilization of the U5-leader stem in the HIV-1 RNA genome affects initiation and elongation of reverse transcription.

Reverse transcription of the Human Immunodeficiency Virus type I (HIV-1) RNA genome is primed by a cellular tRNA-lys3 molecule that binds to the primer binding site (PBS). The PBS is predicted to be part of an extended RNA structure, consisting of a small U5-PBS hairpin and a large U5-leader stem. In this study we stabilized the U5-leader stem of HIV-1 to study its role in reverse transcription...

Recruitment of the nuclear form of uracil DNA glycosylase into virus particles participates in the full infectivity of HIV-1.

The HIV-1 Vpr protein participates in the early steps of the virus life cycle by influencing the accuracy of reverse transcription. This role of Vpr was related to the recruitment of the nuclear form of the uracil DNA glycosylase (UNG2) enzyme into virus particles, but several conflicting findings have been reported regarding the role of UNG2 encapsidation on viral infectivity. Here, we report ...

Functional neutralization of HIV-1 Vif protein by intracellular immunization inhibits reverse transcription and viral replication.

Human immunodeficiency virus type 1 (HIV-1)-encoded Vif protein is important for viral replication and infectivity. Vif is a cytoplasmic protein that acts during virus assembly by an unknown mechanism, enhancing viral infectivity. The action of Vif in producer cells is essential for the completion of proviral DNA synthesis following virus entry. Therefore, Vif is considered to be an important a...

Initiation of HIV Reverse Transcription

Reverse transcription of retroviral genomes into double stranded DNA is a key event for viral replication. The very first stage of HIV reverse transcription, the initiation step, involves viral and cellular partners that are selectively packaged into the viral particle, leading to an RNA/protein complex with very specific structural and functional features, some of which being, in the case of H...

Cold Atmospheric Plasma Inhibits HIV-1 Replication in Macrophages by Targeting Both the Virus and the Cells

Cold atmospheric plasma (CAP) is a specific type of partially ionized gas that is less than 104°F at the point of application. It was recently shown that CAP can be used for decontamination and sterilization, as well as anti-cancer treatment. Here, we investigated the effects of CAP on HIV-1 replication in monocyte-derived macrophages (MDM). We demonstrate that pre-treatment of MDM with CAP red...
