Ultrasound-activated erythrocyte membrane-camouflaged Pt (II) layered double hydroxide enhances PD-1 inhibitor efficacy in triple-negative breast cancer through cGAS-STING pathway-mediated immunogenic cell death

The integration of RmPLH with PD-1 inhibitors substantially amplifies ICD, fostering robust antigen-specific T cell immunity and offering a promising therapeutic strategy for TNBC. This study represents a pioneering application of Pt (II)-based LDH nanocages in oncology, laying a foundation for future innovations in tumor immunotherapy.
