Nanoparticle-Based Immunoengineered Approaches for Combating HIV.

Area of Science:

• Biomedical Engineering
• Immunology
• Virology
• Nanotechnology

Background:

• Highly active antiretroviral therapy (HAART) suppresses HIV replication but does not provide a cure, leaving latent reservoirs intact.
• Latent HIV reservoirs pose a significant barrier to eradication, leading to viral rebound and persistent comorbidities.
• Immunoengineering offers novel strategies to enhance the immune system's therapeutic potential against HIV.

Purpose of the Study:

• To review the current landscape of nanoparticle-based immunoengineering approaches for achieving an HIV cure.
• To highlight the potential of nanotechnology in improving existing HIV therapies and developing novel treatment strategies.

Main Methods:

• Review of preclinical studies on nanoparticle-based immunoengineering for HIV cure.
• Discussion of applications including enhanced drug delivery, latency reversal, vaccine development, and immune cell-based therapies.
• Exploration of nanoparticle roles in targeting viral fusion and gene editing for HIV.

Main Results:

• Nanoparticle-based strategies demonstrate potential for improved delivery of antiretrovirals and latency-reversing agents (LRAs).
• These approaches are being investigated for enhancing vaccine efficacy and facilitating immune-mediated clearance of viral reservoirs.
• Preclinical findings suggest significant promise for nanoparticle immunoengineering in various therapeutic and preventive HIV interventions.

Conclusions:

• Nanoparticle-based immunoengineering represents a promising frontier in the pursuit of a functional or sterilizing cure for HIV/AIDS.
• Further preclinical development is crucial to translate these innovative approaches into clinical applications for HIV treatment and prevention.
