Inhibiting Endothelial Cell‐Mediated T Lymphocyte Apoptosis with Integrin‐Targeting Peptide‐Drug Conjugate Filaments for Chemoimmunotherapy of Triple‐Negative Breast Cancer

T cells, and thus inhibits the growth of primary tumors and pulmonary metastasis. This study highlights the synergistic modulation of cancerous cells and TECs with integrin-targeting PDC filaments as a promising strategy for TNBC chemoimmunotherapy.
