Development of a nanodrug-delivery system camouflaged by erythrocyte membranes for the chemo/phototherapy of cancer.

Aim: Development of a new drug-delivery system using a compound derived from Pronephrium penangianum (J5) for the treatment of cervical cancer. Materials & methods: The delivery system was developed using Prussian blue nanoparticles, camouflaged by red blood cell membrane and with folic acid surface modifications. Results: Our results showed the successful development of a nanodrug-delivery system, which increases the half-life and immune evasion ability of the drug. The mechanism of this system was through suppressing B-cell lymphoma 2 and increasing B-cell lymphoma 2-associated X protein and the cleaved caspase level. An in vivo study also confirmed good antitumor activity without any side effects to normal tissue. Conclusion: This drug-delivery system provides a good alternative for the treatment of cervical cancer using J5.
