Abstract

Background: Aggregation-induced emission (AIE)-based photodynamic therapy (PDT) represents a promising strategy for Cancer treatment for its capacity to activate specific cell death pathways through pronounced oxidative stress. While the activation of specific death pathways has been correlated with PDT efficiency and overall effect, the systematic coordination of oxidative stress across different cell death modalities to amplify therapeutic effects remains unexplored. Current research lacks systematic investigation into how oxidative stress coordinates multiple cell death pathways to amplify therapeutic outcomes of PDT. Methods: We developed an AIE-based nano-photosensitizer (T-T NPs) to induce multimodal cell death through PDT. The system was characterized for mitochondrial targeting capability and Reactive Oxygen Species (ROS) generation. Mechanistic analyses were conducted to evaluate programmed cell death pathways and Ferroptosis induction in tumor. Results: T-T NPs exhibited superior mitochondrial targeting and highly efficient ROS generation. This dual effect successfully triggered PANoptosis and Ferroptosis. The synergistic activation of these pathways significantly enhanced PDT-mediated antitumor efficacy. Conclusion: Our findings reveal that AIE-driven PDT can orchestrate multimodal cell death in tumor through oxidative stress modulation. By concurrently activating PANoptosis and Ferroptosis, this approach establishes a novel paradigm for overcoming limitations of conventional single-pathway targeted PDT.
