Explores a new therapeutic approach for achieving HIV functional cure, suggesting a safer intervention strategy.
In this paper, extensive published literature regarding HIV latent reservoirs and targeted delivery strategies is systematically reviewed. Four mainstream HIV intervention approaches — ART maintenance therapy, Shock and Kill, Block and Lock, and gene editing technology — are compared with respect to their clinical efficacy and inherent safety limitations. Through in-depth analysis of the HIV genome, four core gene fragments driving viral pathogenicity are pinpointed. On this basis, a three-stage sequential physical blocking therapeutic system is established, which comprises sequence-specific blocking enzymes devoid of catalytic activity, gp120-targeted empty VLP delivery vectors, and a low-dose synergistic combination of Bryostatin-1 and JQ1 to reactivate latent viral reservoirs. This work details the rationale for selecting key gene fragments, the full engineering design of the gp120-targeted complex, the practicability of VLP-mediated delivery, the overall three-stage treatment workflow, tailored medication regimens for diverse patient cohorts, and supporting risk management protocols. The proposed therapeutic scheme inhibits viral transcription, integration, host cell invasion and subsequent immune injury solely through the steric hindrance effect of protein macromolecules, with no modification or cleavage of the host human genome. Individualized administration schemes are developed for newly infected patients, populations under long-term ART suppression, elderly patients complicated with hepatic and renal dysfunction, infants, and pregnant women. This study offers theoretical support for developing a low-risk, long-duration HIV functional cure that effectively lowers the risk of viral rebound.
