A gene encoding the cholera toxin B subunit protein (CTB), fused to an endoplasmic reticulum (ER) retention signal (SEKDEL) was inserted adjacent to the bi-directional mannopine synthase P2 promoter in a plant expression vector containing a bacterial luciferase AB fusion gene (luxF) linked to the P1
A gene encoding VP7, the outer capsid protein of simian rotavirus SA11, was fused to the carboxyl terminus of the cholera toxin B subunit gene. A plant expression vector containing the fusion gene under control of the mannopine synthase P2 promoter was introduced into Solanum tuberosum cells by
A cDNA encoding the simian-human immunodeficiency virus (SHIV 89.6p) Tat regulatory element protein was fused to the c-terminus of the cholera toxin B subunit gene (ctxB-tat) and introduced into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated transformation methods. The fusion gene was
A cDNA fragment encoding the V3 loop of human immunodeficiency virus type-1 (HIV-1) envelope glycoprotein gp120 was fused to the cholera toxin B subunit gene (CTB-gp120) and transferred into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated transformation. The CTB-gp120 fusion gene was
A deoxyribonucleic acid (DNA) fragment encoding the cholera toxin B subunit (CTB) was linked 5' to the simian immunodeficiency virus (SIVmac) Gag p27 capsid gene (CTB-Gag). The fusion gene was transferred into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated transformation methods and
A DNA encoding the 27-kDa domain I of anthrax lethal factor protein (LF), was linked to the carboxyl terminus of the cholera toxin B-subunit (CTB-LF). The CTB-LF fusion gene was transferred into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated in vivo transformation methods and
The expression vector, pBI121CTBVP1, containing the fusion of the foot and mouth disease virus (FMDV) VP1 gene and the cholera toxin B subunit (CTB) gene was constructed by fused PCR and transferred into potato (Solanum tuberosum L.) by Agrobacterium-mediated transformation. Transformed plants were
A CTB-NSP4(175) fusion gene encoding the entire 175-aa murine rotavirus NSP4 enterotoxin protein was transferred into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated transformation. The CTB-NSP4(175) enterotoxin fusion gene was detected in the genomic DNA of transformed leaves by PCR
The rates of mosquito-transmitted dengue virus infection in humans have increased in tropical and sub-tropical areas. Domain III of dengue envelope protein (EDIII) is involved in cellular receptor binding and induces serotype-specific neutralizing antibodies. EDIII fused to the B subunit of Vibrio
A real-time polymerase chain reaction (qPCR) assay for the detection of the ctxA gene of toxigenic Vibrio cholerae (Vc) was validated against standard culture techniques. The first experimental phase determined optimal enrichment conditions for detection by culture and qPCR of Vc in shrimp, bottled
Developments in recombinant DNA technology have enabled molecular biologists to introduce a variety of novel genes into plant species for specific purposes. From crop improvement to vaccine antigen and antibody production, plants are attractive bioreactors for production of recombinant proteins, as
Oral administration of disease-specific autoantigens can prevent or delay the onset of autoimmune disease symptoms. We have generated transgenic potato plants that synthesize human insulin, a major insulin-dependent diabetes mellitus autoantigen, at levels up to 0.05% of total soluble protein. To
Transgenic potatoes were engineered to synthesize a cholera toxin B subunit (CTB) pentamer with affinity for GMI-ganglioside. Both serum and intestinal CTB-specific antibodies were induced in orally immunized mice. Mucosal antibody titers declined gradually after the last immunization but were
The production of plant-derived pharmaceuticals essentially requires stable concentrations of plant constituents, especially recombinant proteins; nonetheless, soil and seasonal variations might drastically interfere with this stability. In addition, variability might depend on the plant organ used
The housefly, Musca domestica L. (Diptera: Muscidae), is recognized as an important factor in the dissemination of various infectious diseases such as cholera, shigellosis, and salmonellosis. They can also serve as a cross-contamination vector for other foodborne pathogens. However, the potential
