Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Area of Science:

Immunology
Virology
Clinical Trials

Background:

Post-treatment control after antiretroviral therapy (ART) is understood, but post-intervention control after immunotherapy for HIV cure is less clear.
Identifying mechanisms of immune control is vital for developing effective HIV cure strategies.

Purpose of the Study:

To provide an overview of recent studies identifying post-intervention controllers in HIV cure-related immunotherapy trials.
To review potential mechanisms driving the post-intervention control phenotype.

Main Methods:

Review of recent immunotherapy clinical trials for HIV cure.
Analysis of identified post-intervention controllers and their underlying mechanisms.

Main Results:

Post-intervention controllers were observed in trials using broadly neutralizing antibodies, immune modulators, T cells, checkpoint inhibitors, and gene therapy.
Significant variability exists in defining post-intervention control and evaluating its mechanisms across studies.
Mechanisms include antibody activity and enhanced HIV-specific T cell function.

Conclusions:

While no definitive HIV control strategy has emerged, small numbers of post-intervention controllers have been identified.
Standardized definitions and assessment methods for post-intervention control are needed.
Standardization will facilitate cross-trial comparisons and accelerate HIV cure research.
