HIV Eradication Strategies: Implications for the Central Nervous System

Area of Science:

• Virology
• Neuroscience
• Immunology

Background:

• Current HIV-1 management relies on antiretroviral therapy (ART) and preventive measures.
• HIV-1 eradication is being explored as a strategy to combat the AIDS epidemic.
• Research is actively pursuing sterilizing or functional cures for HIV-1 infection.

Purpose of the Study:

• To evaluate the implications of HIV-1 eradication strategies on the central nervous system (CNS).
• To investigate the CNS as a potential latent reservoir for HIV-1.
• To determine if HIV-1 can persist and reactivate within the CNS during and after combination antiretroviral therapy (cART).

Main Methods:

• Review of existing research on HIV-1 reservoirs and eradication strategies.
• Analysis of studies investigating HIV-1 infection in CNS cells like macrophages and astrocytes.
• Examination of the controversial role of the CNS as a latent HIV-1 reservoir.

Main Results:

• The CNS is susceptible to HIV-1 infection, with macrophages and astrocytes being potential viral reservoirs.
• It remains uncertain whether the CNS harbors latent HIV-1 during cART.
• The potential for viral reactivation and spread from the CNS after ART interruption is not fully established.

Conclusions:

• HIV-1 eradication strategies must consider the CNS, irrespective of its definitive role as a reservoir.
• Further research is needed to ascertain the presence and significance of latent HIV-1 in the CNS across all patients.
• Understanding CNS viral dynamics is crucial for developing effective HIV-1 cure protocols.
