Antigen Orientation Boosts HPV Cancer SNA Vaccine, Slows Tumors in Models
Northwestern researchers engineered a spherical nucleic acid (SNA) vaccine in which the HPV16 E7 peptide is displayed at the nanoparticle surface via its N‑terminus. This N‑terminal orientation (N‑HSNA) generated up to eight‑fold higher interferon‑γ secretion and 2.5‑fold greater cytotoxicity than alternative configurations. In HPV‑positive mouse models, N‑HSNA reduced tumor burden more than threefold and extended survival, while patient‑derived spheroids showed a 2.5‑fold increase in tumor‑cell killing. The work demonstrates that precise antigen placement can dictate therapeutic potency in cancer vaccines.
