Abstract
We investigated the potential of Nicotiana benthamiana to express the E7 protein of human papillomavirus 8 (HPV-8), a paradigm genotype among cutaneous HPVs. The protein, modified in its putative pRb-binding domain (E7QGD), was transiently expressed in leaves following infiltration with agrobacteria carrying either a binary vector combined with silencing suppressor constructs or replicating tobacco mosaic virus (TMV)-based vectors with different targeting signals. HPV-8 E7QGD yields ranged from 250 ng to 4.6 mg per gram of fresh leaf tissue. The highest yields were obtained with TMV-based vectors targeting the antigen to the apoplast. HPV8-CER (H2q) mice transformed with the complete early region of HPV-8 showed a delay in the onset of skin papillomatous lesions and produced E7-specific immunoglobulins G when inoculated subcutaneously with leaf extracts expressing E7QGD. Furthermore, we demonstrated that the plant-made HPV-8 E7QGD induced a specific cytotoxic response in C57BL/6 (H2b) mice.
