The challenge of HIV persistence in the era of antiretroviral therapy

Summary

The central thesis of "The challenge of HIV persistence in the era of antiretroviral therapy" is that despite the efficacy of antiretroviral therapy (ART) in suppressing viral replication, the establishment and maintenance of viral reservoirs pose a fundamental barrier to HIV eradication. This book examines the biological mechanisms underlying HIV persistence, focusing on cellular reservoirs where the virus integrates into the host genome and remains dormant, thereby evading immune detection and ART. It details the limitations of current ART in eliminating these reservoirs and highlights the critical need for novel therapeutic strategies.

The book delineates key concepts such as the latent reservoir, the role of specific cell types in viral persistence, and the challenges in developing curative interventions. Readers will gain a comprehensive understanding of the scientific hurdles in achieving a functional cure for HIV, moving beyond viral suppression to complete eradication. It underscores the ongoing research efforts directed at understanding reservoir dynamics and developing innovative treatment modalities.

Key concepts

• Viral Reservoir — Latently infected cells where HIV can hide and persist, making eradication difficult.
• Latency Reversal — Strategies aimed at reactivating dormant HIV from reservoirs to make it susceptible to ART or immune clearance.
• HIV Eradication — The ultimate goal of eliminating all HIV from the body, contrasting with viral suppression achieved by ART.
• Immune Control — The role of the host's immune system in managing residual viral replication and potentially contributing to viral clearance.
