The HIV reservoir landscape in elite controllers

Area of Science:

• Immunology
• Virology
• Infectious Diseases

Background:

• Elite controllers represent a unique subset of individuals with Human Immunodeficiency Virus (HIV) infection who naturally control viral replication without antiretroviral therapy.
• The persistence of a viral reservoir, a sanctuary for latent virus, remains a major barrier to achieving a functional cure for HIV.

Purpose of the Study:

• To characterize the heterogeneity of the HIV-1 reservoir in elite controllers.
• To correlate distinct reservoir profiles with different HIV progression phenotypes observed in elite controllers.

Main Methods:

• Review of studies employing high-resolution techniques to analyze the HIV-1 viral reservoir.
• Comparative analysis of reservoir characteristics in elite controllers with persistent viral remission versus those who eventually lose control.

Main Results:

• The HIV-1 reservoir in elite controllers is demonstrably heterogeneous.
• Distinct reservoir characteristics were identified between elite controllers who maintain viral control and those who progress.
• Exceptional cases within the persistent remission group exhibit reservoir profiles suggestive of "block and lock" phenomenon or potential sterilizing cure.

Conclusions:

• The heterogeneity of the HIV-1 reservoir in elite controllers is a critical finding.
• Differentiating reservoir profiles offers valuable insights for advancing HIV cure strategies.
• Further research into these distinct reservoir characteristics may unlock pathways to a definitive HIV cure.
