HIV-specific CD8⁺ T cells and HIV eradication.

Area of Science:

• Immunology
• Virology
• Infectious Diseases

Background:

• Combination antiretroviral therapy (cART) effectively suppresses HIV replication.
• HIV establishes latent reservoirs in resting CD4+ T cells, evading cART and immune detection.
• Reversing HIV latency is a key strategy for achieving a functional cure.

Purpose of the Study:

• To explore the antiviral potential of HIV-specific CD8+ T cells.
• To investigate methods for enhancing the efficacy of HIV-specific CD8+ T cells against latent reservoirs.
• To assess the role of CD8+ T cells in achieving HIV eradication or a functional cure.

Main Methods:

• Review of current literature on HIV latency and CD8+ T cell function.
• Analysis of emerging strategies for latency reversal.
• Discussion of immunological approaches to target persistent HIV.

Main Results:

• Pharmacological latency reversal can induce viral protein expression in resting CD4+ T cells.
• HIV-specific CD8+ T cells can recognize and potentially eliminate reactivated infected cells.
• Effective harnessing of CD8+ T cells is crucial for viral eradication.

Conclusions:

• Targeting latent HIV reservoirs by reversing latency and engaging HIV-specific CD8+ T cells offers a promising path toward a functional cure.
• Further research is needed to optimize strategies for harnessing CD8+ T cell-mediated clearance of reactivated HIV.
• The combination of latency-reversing agents and enhanced T cell immunity holds potential for HIV eradication.
