纳米材料作为载体在癌症免疫疗法中的研究及应用

he main goal of anti-cancer therapyis to specifically inhibit the activity of cancer cells without affecting the function of normal cells.In recent years,with the development of cancer immunotherapy, a great transformation has taken place in the treatment of many cancers, especially melanoma, kidney cancer, bladder cancer and lung cancer.Cancer immunotherapy improves immune response efficiency, most importantly, increases overall survival of patients.Cancer immunotherapy refers to any treatment that enhances the patient\'s immune system to against cancer.Monoclonal antibodies, Toll-like receptor agonists, cell penetrating peptides and cell targeting peptides play important roles in current immunotherapy, but their clinical application is still subject to many limitations. This review summarizes several delivery options and describes ways to improve their targeting, cellular uptake, and immunostimulatory activity.
