Expression of protective antigens in transgenic chloroplasts
View Patent ↗Vectors and methods for plastid transformation of plants to produce protective antigens and vaccines for oral delivery are provided. The invention provides edible vaccines for conferring immunity to a mammal against Bacillus anthracis , as well as Yersina pestis.
1. A plastid transformation vector for stably transforming a plastid, said plastid vector comprising, as operably linked components, a first flanking sequence, at least one regulatory sequence operable in a plastid, a DNA sequence coding for a protective antigen, a DNA sequence coding for a chaperonin, and a second flanking sequence.
2. A plastid transformation vector for stably transforming a plastid, said plastid vector comprising, as operably linked components, a first flanking sequence, at least one regulatory sequence operable in a plaslid, a DNA sequence coding for a protective antigen, a DNA sequence coding for a chaperonin, and a second flanking sequence, wherein said protective antigen is a bacterial antigen.
