Despite the approval of several artificial nanotherapeutics for treatment triple-negative breast cancer (TNBC), significant challenges, including unsatisfactory therapeutic outcomes, severe side effects, and high cost large-scale production, still restrict their long-term application. In contrast, plant-derived extracellular vesicles (PEVs) exhibit promising potential in therapy due to negligible systemic toxicity, bioavailability cost- effectiveness. this study, we developed an alternative strategy inhibit TNBC via Platycodon grandiflorum (PG)-derived (PGEVs). The PGEVs were isolated by ultracentrifugation sucrose gradient centrifugation method contained adequate functional components such as proteins, lipids, RNAs active molecules. exhibited remarkable stability, tolerating acidic digestion undergoing minimal changes simulated gastrointestinal fluid. They efficiently taken up tumor cells induced increased production reactive oxygen species (ROS), leading cell proliferation inhibition apoptosis, particularly line 4T1. Additionally, facilitated polarization tumor-associated macrophages (TAMs) toward M1 phenotype secretion pro-inflammatory cytokines. Further vivo investigations revealed that accumulated 4T1 tumors exerted effects through boosting anti-tumor immune responses modulating gut microbiota whether administered orally or intravenously (i.v.). conclusion, these findings highlight a natural, biocompatible efficient nanotherapeutic candidate treating TNBC.
