Plant-derived vaccines represent an attractive strategy for cancer immunotherapy due to their relative safety and cost-effectiveness. We evaluated the anti-tumour activity of a Nicotiana benthamiana produced vaccine candidate based on the non-transforming E7 protein of HPV-16 fused to β-1,3-1,4-glucanase of Clostridium thermocellum. Two doses of vaccine at two week intervals were administered to groups of C57BL/6 mice starting 3 or 6 days after challenge with tumourigenic E7-expressing TC-1* cells. Inhibition of tumour growth and increased survival was observed in both groups treated with vaccine. These data suggest the potential of plants as a platform for producing therapeutic vaccines. © 2009 Elsevier Ltd. All rights reserved.
