Overview

Experimental study demonstrates tumor growth inhibition and metastasis suppression in tumor models, suggesting a viable platform for multi-pathway photoimmunotherapy.

Key Points

To develop a targeted nanosystem that amplifies oxidative stress via multiple pathways to enhance synergistic photothermal, photodynamic, and tumor immunotherapy.
Engineered transferrin-targeted nanoparticles (D/I@HST NPs) encapsulating dihydroartemisinin and IR-780 to bind overexpressed transferrin receptors on tumor cells.
Activated nanoparticles using 808-nm laser irradiation and endogenous acidic microenvironment conditions to trigger iron-catalyzed reactions and ROS-responsive drug release.
Amplified oxidative stress and photothermal heating triggered immunogenic cell death, driving dendritic cell maturation and increasing T-cell infiltration and activation.
Treatment led to significant decreases in immunosuppressive myeloid-derived suppressor cells alongside substantial suppression of primary tumor growth and lung metastasis.
