Implication

Preclinical study demonstrates that a dual-targeting nanoplatform eradicates primary tumors and inhibits distal lesions in breast cancer models, highlighting a route to remodel cold tumors.

Key Points

To develop a dual-organelle-targeted liposomal nanoplatform capable of transforming immunosuppressive 'cold' triple-negative breast tumors into immunogenic tumors through phototherapy-coupled cell death pathways.
Engineered BMFL, a folate receptor-targeted liposome co-encapsulating an aggregation-induced emission luminogen (BITT) and a STING agonist (MSA-2) designed to target lipid droplets and lysosomes.
Tested photoimmunotherapy responses, organelle-specific damage, and systemic immune activation in vitro and across a bilateral murine triple-negative breast cancer model under near-infrared irradiation.
BMFL-mediated phototherapy promoted lipid droplet peroxidation-driven ferroptosis and lysosomal immunogenic cell death, prompting mitochondrial DNA leakage that synergized with MSA-2 to strongly activate the cGAS–STING axis.
In bilateral tumor models, the combined treatment completely eliminated irradiated primary tumors and induced systemic adaptive antitumor immunity that suppressed non-irradiated distal tumors.
