Assembly of Human Papillomavirus 16 L1 Protein in Nicotiana benthamiana Chloroplasts into Highly Immunogenic Virus-Like Particles.
Infection with human papillomavirus (HPV) can cause cervical cancers in women, and vaccination against the virus is one of most effective ways to prevent these cancers. Two vaccines made of virus-like particles (VLPs) of HPV L1 proteins are currently commercially available. However, these HPV vaccines are highly expensive, and thus not affordable for women living in developing countries. Therefore, great demand exists to produce a cost-effective vaccine. Here, we investigate the production of self-assembled HPV16 VLPs in plants. We generated a chimeric protein composed of N-terminal 79 amino acid residues of RbcS as a long-transit peptide to target chloroplasts, the SUMO domain, and HPV16 L1 proteins. The chimeric gene was expressed in plants with chloroplast-targeted bdSENP1, a protein that specifically recognizes the SUMO domain and cleaves its cleavage site. This co-expression of bdSENP1 led to the release of HPV16 L1 from the chimeric proteins without any extra amino acid residues. HPV16 L1 purified by heparin chromatography formed VLPs that mimicked native virions. Moreover, the plant-produced HPV16 L1 VLPs elicited strong immune responses in mice without adjuvants. Thus, we demonstrated the cost-effective production of HPV16 VLPs in plants.

期刊介绍:
Journal of Plant Biology, an official publication of the Botanical Society of Korea, is an international journal devoted to basic researches in biochemistry, cellular biology, development, ecology, genetics, molecular biology, physiology, and systematics of plants.
The Journal publishes the following categories of paper:
Original articles -- For publication in Journal of Plant Biology the manuscript must provide a significant new contribution to our understanding of plants. All areas of plant biology are welcome. No limit on the length, but a concise presentation is encouraged.
Reviews -- Invited by the EiC.
Brief Communications -- Concise but independent report representing significant contribution to plant science.
The Botanical Society of Korea was founded on November 30, 1957 to promote studies, disseminate and exchange information on the field of plant biology. The first issue of The Korean Journal of Botany, the official publication of the society, was published on April 1, 1958. It was published twice a year, but quarterly from 5th volume in 1962. In 1994, it was renamed to Journal of Plant Biology and published in English since 1996. The journal entered its 50th year of publication in 2007.
