Impact of misclassified defective proviruses on HIV reservoir measurements [PDF]

Nature Communications, 2023
Most proviruses persisting in people living with HIV (PWH) on antiretroviral therapy (ART) are defective. However, rarer intact proviruses almost always reinitiate viral rebound if ART stops. Therefore, assessing therapies to prevent viral rebound hinges

HIV reservoirs are dominated by genetically younger and clonally enriched proviruses

mBio, 2023
In order to cure human immunodeficiency virus (HIV), we need to better understand the within-host evolutionary origins of the small reservoir of genome-intact proviruses that persist within infected cells during antiretroviral therapy (ART).

Intranuclear Positions of HIV-1 Proviruses Are Dynamic and Do Not Correlate with Transcriptional Activity

mBio, 2022
The relationship between spatiotemporal distribution of HIV-1 proviruses and their transcriptional activity is not well understood. To elucidate the intranuclear positions of transcriptionally active HIV-1 proviruses, we utilized an RNA fluorescence in ...

Within-Subtype HIV-1 Polymorphisms and Their Impacts on Intact Proviral DNA Assay (IPDA) for Viral Reservoir Quantification [PDF]

Viruses
The Intact Proviral DNA Assay (IPDA) is widely used to quantify genome-intact HIV proviruses in people living with HIV, but viral sequence diversity has been observed to cause assay failures due to primer/probe mismatches.

Unequal distribution of genetically-intact HIV-1 proviruses in cells expressing the immune checkpoint markers PD-1 and/or CTLA-4

Frontiers in Immunology, 2023
IntroductionHIV-1 persists in resting CD4+ T-cells despite antiretroviral therapy (ART). Determining the cell surface markers that enrich for genetically-intact HIV-1 genomes is vital in developing targeted curative strategies.

Comparative HIV-1 Proviral Dynamics in Two Individuals That Maintained Viral Replication Control with or without Antiretroviral Therapy following Superinfection

Viruses, 2022
The analysis of the HIV-1 proviral dynamics after superinfection in the context of both natural and antiretroviral therapy (ART)-mediated suppression could yield unique insights into understanding the persistence of viral variants that seeded the ...

The largest HIV-1-infected T cell clones in children on long-term combination antiretroviral therapy contain solo LTRs

mBio, 2023
Combination antiretroviral therapy (cART) suppresses viral replication but does not cure HIV infection because a reservoir of infectious (intact) HIV proviruses persists in long-lived CD4+T cells.

Measuring the latent reservoir for HIV-1: Quantification bias in near full-length genome sequencing methods.

PLoS Pathogens, 2022
Antiretroviral therapy (ART) effectively inhibits HIV-1 replication but is not curative due to the persistence of a latent viral reservoir in resting CD4+ T cells. This reservoir is a major barrier to cure.

Dynamic Shifts in the HIV Proviral Landscape During Long Term Combination Antiretroviral Therapy: Implications for Persistence and Control of HIV Infections

Viruses, 2020
Combination antiretroviral therapy (cART) controls but does not eradicate HIV infection; HIV persistence is the principal obstacle to curing infections.

Emerging PCR-based techniques to study HIV-1 reservoir persistence [PDF]

, 2020
While current antiretroviral therapies are able to halt HIV-1 progression, they are not curative, as an interruption of treatment usually leads to viral rebound.
