ABSTRACT
The biomimetic strategy of using the cell membrane-coated nanoparticles can retain the physical and chemical properties of the nanoparticles and show the biological characteristics of the source cell membrane, which can further enhance the role of the nanodrug in tumor treatment. A hybrid cell membrane is the fusion of two or more different types of cell membranes. A hybrid cell membrane can endow nanoparticles with multiple biofunctions derived from the source cells compared with a single cell membrane. Hybrid cell membranes provide a foundation to stimulate extensive research into multifunctional biomimetic nano-drug delivery system (NDDS), which is expected to broaden the application of biomimetic nanotechnology in drug delivery systems. In this review paper, the types of hybrid cell membrane used to construct nano-drug delivery systems, the preparation and characterization methods, and cancer treatment research progress in recent years were reviewed.
ABSTRACT
Although the combination of surgery, radiotherapy and chemotherapy is the main methods of cancer treatment, it still fails to solve certain tumors, especially metastatic tumors. With the in-depth study of tumorigenesis and development mechanism, and the exploration and clinical application of tumor immunotherapy, the survival period of patients with malignant tumors has been significantly prolonged. Tumor immunotherapy has become an effective anti-tumor method by activating the body′s own immune system to achieve tumor suppression. The combination of chemotherapy and immunotherapy has a significant effect and has become a feasible solution for cancer treatment. The rationally designed nanomedicines can effectively combine chemical drugs and immunological preparations, and have become an effective delivery carrier basis and treatment means for clinically targeting tumor tissues, synergistic immune mechanisms to kill tumor cells, and treating tumors. In this paper, the types of multifunctional nanomedicines used in chemotherapy and various immunotherapies in recent years and their advantages in cancer therapy were reviewed.
