Area of Science:

• Virology
• Immunology
• Molecular Biology

Background:

• Human immunodeficiency virus (HIV) latency presents a significant challenge to eradicating infected cells.
• During latency, HIV replication is minimal, producing few viral proteins, rendering it undetectable by antiretroviral therapies and the immune system.
• HIV latency is reversible, often reactivating upon interruption of antiretroviral treatment, necessitating lifelong therapy.

Purpose of the Study:

• To describe the mechanisms governing HIV gene transcription.
• To review molecules associated with the "block and lock" strategy for maintaining deep HIV latency.
• To provide insights for developing novel therapeutic approaches targeting latent HIV.

Main Methods:

• Review of existing literature on HIV latency.
• Analysis of mechanisms regulating viral gene transcription.
• Examination of the "block and lock" therapeutic strategy.

Main Results:

• Detailed description of viral gene transcription processes.
• Identification of key molecular players in maintaining HIV latency.
• Overview of potential therapeutic molecules for the "block and lock" strategy.

Conclusions:

• Understanding HIV transcription mechanisms is crucial for developing effective latency-targeting therapies.
• The "block and lock" strategy offers a promising avenue for achieving sustained HIV latency.
• Further research into these mechanisms and molecules is essential for advancing HIV eradication efforts.
