Summary
Elite controllers naturally suppress HIV without treatment, offering a biological blueprint for a functional cure. Understanding their mechanisms is key to developing scalable, long-term remission strategies for HIV.
Area of Science:
- Immunology
- Virology
- Genetics
Background:
- Antiretroviral therapy (ART) manages HIV but is not curative, requiring lifelong adherence.
- Stem cell transplantation (SCT) offers potential cure but is unsafe and not scalable.
- Elite controllers (ECs) naturally control HIV replication without ART, providing a model for cure research.
Purpose of the Study:
- To review the biological mechanisms underlying natural HIV suppression in elite controllers.
- To examine the characteristics and implications of elite control.
- To explore translational strategies inspired by EC biology for HIV cure.
Main Methods:
- Synthesis of current evidence on EC biology, including viral, genetic, and immune factors.
- Examination of demographic, clinical, and case report data.
- Discussion of translational research strategies for HIV remission.
Main Results:
- ECs demonstrate sustained, treatment-free viral suppression and stable health.
- Multiple factors, including viral, host genetic, and immune mechanisms, contribute to elite control.
- Insights from ECs inform novel therapeutic approaches.
Conclusions:
- Understanding elite control provides a biological roadmap for developing a functional HIV cure.
- Lessons from ECs are crucial for advancing scalable, safe, and durable HIV remission strategies.
- Elite control research is central to efforts to end the HIV epidemic.

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...

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
