Immunotoxin exerts its anti-cancer effects through inhibiting protein synthesis in cancer cells and promoting cancer cell apoptosis. Although immunotoxin is characterized by high toxicity and specificity which may provide remarkable potential in tumor therapy compared with traditional anti-cancer drugs, there are a lot of limitations for its clinical application.
