Also known as: Env trimer vaccines, native-like envelope trimer vaccines
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Antibody-based interventions primarily involve inducing broadly neutralizing antibodies (bNAbs) through native-like envelope (Env) trimer vaccines
Usefulness & Problems
Why this is useful
Native-like Env trimer vaccines are described as a way to induce broadly neutralizing antibodies in HIV-1 cure strategies. They function as the vaccine immunogen platform in the abstract's antibody arm.; inducing broadly neutralizing antibodies against HIV-1

Published Workflows
Objective: Develop an HIV-1 cure framework that combines neutralizing antibodies, precision genome editing, and latent reservoir management rather than relying on monotherapy.
Why it works: The abstract argues that combining complementary modalities can address limitations of ART and monotherapies by jointly targeting viral replication, latent reservoirs, and immune dysfunction.

CAR-T cells and bispecific antibodies are engineered therapeutic modalities for subsequent immune clearance in HIV-1 cure strategies.
Engineered cellular therapies include chimeric antigen receptor T (CAR-T) cells or bispecific antibodies (bsAbs) for subsequent immune clearance
Current multimodal HIV-1 cure strategies face challenges including suboptimal Env vaccine immunogenicity, off-target effects and inefficient delivery of gene editing tools, incomplete latent virus reactivation, and limitations of preclinical models.
Despite these advances, challenges remain, including suboptimal immunogenicity of Env vaccines, off-target effects and inefficient delivery of gene editing tools, incomplete reactivation of latent viruses, and limitations of preclinical models.
Future work should optimize synergistic effects by improving Env trimer design, enhancing CRISPR targeting specificity, and developing preclinical models that better reflect human immunity.

ART suppresses HIV-1 replication but cannot eliminate latent viral reservoirs and has limitations including lifelong treatment need and risk of drug resistance.
Despite its potency in suppressing HIV-1 replication, antiretroviral therapy (ART) cannot eliminate latent viral reservoirs and is associated with several limitations, such as the need for lifelong treatment and the inherent risk of drug resistance.

Precision genome editing for HIV-1 cure can be achieved using CRISPR/Cas together with long-acting slow-effective release antiretroviral therapy.
Precision genome editing can be achieved by using clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) along with long-acting slow-effective release antiretroviral therapy.
Reservoir-targeted therapies are typically implemented by reactivating latent viruses using the shock and kill strategy.
