- Abstract
- Photodynamic therapy combined with immunogenic cell death has been proposed to overcome the unsolvable problems of single therapy, such as high levels of tumor recurrence and treatment resistance of tumors. Previous works on this theme have mostly concentrated on endoplasmic reticulum (ER)-stressed damage-associated molecular patterns (DAMPs), ignoring the secretion and function of mitochondria-related DAMPs. Herein, our work reports two intersystem crossing photosensitizers based on well-designed multiarylpyrrole structures and draws valuable attention to mitochondria-related DAMP-TFAM (mitochondrial transcription factor) when cancer cells are under forceful oxidative stress. The tumors vanished, and immunogenic experiments were applied to illuminate the advantages of double treatment. Our discovery of new mitochondria-related DAMPs compensates for the lack of ER-stressed DAMPs and offers an innovative target for immunity therapy.
