Controlling HIV-1: Non-Coding RNA Gene Therapy Approaches to a Functional Cure

Area of Science:

• Virology
• Immunology
• Molecular Biology

Background:

• Combined antiretroviral therapy (cART) manages HIV-1 by suppressing viremia, but a latent reservoir in CD4(+) T cells necessitates lifelong treatment.
• This persistent viral reservoir is a primary obstacle to eradicating HIV-1 infection.
• Understanding HIV-1 transcription and latency mechanisms is key to developing new therapeutic strategies for a functional cure.

Purpose of the Study:

• To review recent advancements in non-coding RNAs (ncRNAs), particularly siRNA and shRNA, for targeting HIV-1 transcription.
• To discuss the potential of these ncRNAs as future therapeutics to address the latent HIV-1 reservoir.
• To briefly cover animal models and gene therapy trials for potential HIV-1 treatments.

Main Methods:

• Literature review focusing on ncRNAs (siRNA, shRNA) and their role in HIV-1 transcription and latency.
• Analysis of studies investigating molecular mechanisms of viral regulation.
• Examination of data on animal models and clinical gene therapy trials.

Main Results:

• ncRNAs, including siRNA and shRNA, show promise in regulating HIV-1 transcription and potentially impacting the latent reservoir.
• These RNA-based strategies offer a novel approach to combatting persistent HIV-1 infection.
• Ongoing research and clinical trials are exploring the efficacy of gene-based therapies.

Conclusions:

• siRNA and shRNA represent promising therapeutic avenues for targeting the latent HIV-1 reservoir.
• Further research into ncRNA mechanisms is crucial for developing effective strategies toward a functional HIV-1 cure.
• The development of targeted therapeutics and gene therapy holds potential for future HIV-1 treatment paradigms.
