Dynamically Deformable Protein Delivery Strategy Disassembles Neutrophil Extracellular Traps to Prevent Liver Metastasis

Neutrophil extracellular traps (NETs) are capable of adhering to the cancer cell surface and promoting the migration and invasion of cells towards the liver, subsequently forming hepatic metastases. Thus, a dynamically deformable protein delivery strategy (PAAP/DNase-1) is developed for liver metastasis prevention in patients with metastatic colon or...
