Adjunctive and long-acting nanoformulated antiretroviral therapies for HIV-associated neurocognitive disorders.

PURPOSE OF REVIEW: We are pleased to review current and future strategies being developed to modulate neuroinflammation while reducing residual viral burden in the central nervous system. This has been realized by targeted long-acting antiretroviral nano and adjunctive therapies being developed for HIV-infected people. Our ultimate goal is to eliminate virus from its central nervous system reservoirs and, in so doing, reverse the cognitive and motor dysfunctions. RECENT
FINDINGS: Herein, we highlight our laboratories' development of adjunctive and nanomedicine therapies for HIV-associated neurocognitive disorders. An emphasis is placed on drug-drug interactions that target both the viral life cycle and secretory proinflammatory neurotoxic factors and signaling pathways.
SUMMARY: Antiretroviral therapy has improved the quality and duration of life for people living with HIV-1. A significant long-term comorbid illness is HIV-associated neurocognitive disorders. Symptoms, although reduced in severity, are common. Disease occurs, in part, through continued low-level viral replication, inducing secondary glial neuroinflammatory activities. Our recent works and those of others have seen disease attenuated in animal models through the use of adjunctive and long-acting reservoir-targeted nanoformulated antiretroviral therapy. The translation of these inventions from animals to humans is the focus of this review.
