Advanced Science, EarlyView.AUTACE is a bifunctional nanoplatform that integrates tumor targeting, immune engagement, and on‐demand KRAS degradation. It targets KRAS/TP53 co‐mutant tumors via TP53‐specific TCRs, elicits antitumor CD8+ T‐cell responses through surface anti‐CD3 antibodies, and uses low‐intensity focused ultrasound (LIFU) to trigger controlled release of the KRAS ...
