Tumor-targeted multifunctional extracellular vesicles as drug carriers for lung cancer therapy.

ABSTRACT: Aim: Chemotherapy continues to be the frontline treatment for lung cancer patients. However, treatment-related toxicity and off-target effects limit the use of chemotherapy. Therefore, improvements in delivering chemotherapeutics with reduced toxicity to normal tissues are needed. In the present study, we combined nanotechnology with extracellular vesicle (EV) technology to produce tumor-targeted multifunctional EVs (tt-Mfn-EVs) as drug carriers for cancer therapy. Methods: The tt-Mfn-EVs were formulated by exogenously loading EVs with gold nanoparticles conjugated to cisplatin (CDDP) via pH-sensitive coordination ester linkage. Attached to the outer surface of drug-loaded EVs is the transferrin ligand for targeting transferrin receptor (TfR) overexpressing lung cancer cells.
