To review the immunological mechanisms of bacterial superantigens and evaluate protein engineering strategies developed to safely deploy them in cancer immunotherapy.
Analyzed structural mechanisms of superantigen-mediated cross-linking between MHC class II molecules and T-cell receptor Vβ domains.
Evaluated bioengineering platforms including low-toxicity mutants, antibody-superantigen fusions, and nanoparticle formulations designed to reduce systemic toxicity.
Reviewed preclinical and clinical evidence for combining superantigens with checkpoint inhibitors and adoptive cell therapies.
Bacterial superantigens induce broad polyclonal T-cell activation by bypassing conventional antigen-processing pathways.
Engineered delivery formats and attenuated mutants selectively concentrate immune activation at tumor sites, mitigating severe systemic cytokine release.
Superantigen platforms successfully reprogram immunosuppressive tumor microenvironments and enhance the efficacy of immune checkpoint blockade and adoptive T-cell therapies.
