  • Recombinant human papillomavirus vaccine expressed in transgenic plants
    Patent number: 6444805
    Abstract: The oral vaccine of the present invention containing the HPV like particles is produced in edible transgenic plants and then administered through the consumption of the edible portion of those plants or after the purification of the particles. A DNA sequence encoding one of the HPV capsid proteins is isolated, inserted into the plasmid which comprises a plant-specific promoter and a gene for a selection marker, and then transferred to plant cells to give transgenic plants. Since the gene is expressed in a portion of the plants, the oral vaccine of the present invention can be produced in an inexpensive manner and administered in a simple method.
