Additionally, the Pha‐PLG self‐assembles into nanofibers within the cells, prolonging circulation time, enhancing immune induction, and activating a robust immune response by CD8+ T cells, thus initiating a powerful tumor‐immune cycle.[37] This strategy, which combines HER2 protein degradation with PDT and ICD effects, offers a novel approach to breast cancer treatment. This evidence concerns the gene ERBB2 and breast carcinoma.
