Deep latency: A new insight into a functional HIV cure.

Area of Science:

• Virology and Immunology
• Infectious Diseases
• Molecular Biology

Background:

• The latent human immunodeficiency virus (HIV) reservoir remains the primary barrier to a cure, persisting despite effective antiretroviral therapy (ART).
• Current strategies like stem cell transplantation, gene editing, and 'Shock and Kill' face significant challenges, including high risks, off-target effects, and limited efficacy in reducing reservoir size.

Purpose of the Study:

• To review an emerging strategy focused on deeply silencing latent HIV reservoirs.
• To discuss the development, potential, and limitations of deep silencing for HIV remission and cure.
• To explore future directions for controlling latent HIV and preventing viral rebound.

Main Methods:

• Review of existing literature and proposed strategies for HIV reservoir control.
• Analysis of the concept of deep silencing as an alternative therapeutic approach.
• Discussion of potential mechanisms, clinical translation challenges, and future research avenues.

Main Results:

• Current HIV cure strategies have limitations hindering clinical application and efficacy.
• Deep silencing presents a promising alternative by targeting the persistence of latent HIV.
• Further research is needed to fully understand and optimize deep silencing strategies.

Conclusions:

• Deep silencing of latent HIV reservoirs is a developing strategy with potential for HIV remission.
• Overcoming the challenges associated with this approach is crucial for achieving a functional HIV cure.
• Continued investigation into deep silencing mechanisms and clinical applications is warranted.
