    摘要: The subject invention provides, for example, a novel approach to specifically induce intranasal and/or oral mucosal as well as humoral antibody response by administrating a mucosal delivery pentabody complex (MDPC). The MDPC is a complex formed by mixing a target antigen and a mucosal delivery pentabody (MDP) that has a strong affinity to the target antigen. The MDP is a fusion protein of a single domain antibody (sdAb; which binds to the target antigen specifically) to a pentamerization domain (which can include the B-subunit of an AB5 toxin family, including the B subunit of cholera toxin (CT) or heat-labile toxin (LT)). The pentamerization domain can self-assemble into a pentamer, through which a pentameric single domain antibody, or a pentabody, is formed.

    摘要: A method of introducing a molecule of interest into a plant cell having a cell wall includes interacting a gamma-zein peptide with a molecule of interest to form a gamma-zein linked structure. The gamma-zein linked structure is then placed in contact with the plant cell having a cell wall, and allowing uptake of the gamma-zein linked structure into the plant cell. Alternatively, a gene of interest can be expressed in a plant cell having an intact cell wall by interacting a gamma-zein peptide with the gene of interest to form a gamma-zein linked gene structure, allowing uptake of the gamma-zein linked gene structure into the plant cell, and expressing the gene of interest in the plant cell and its progeny.

    摘要: This invention pertains in part to the development of a vaccine for poultry against necrotic enteritis (NE). The vaccine utilizes a protective antigen that is a mutated, full-length, non-toxic Clostridium perfringens (Cp) α-toxin protein (Mcpa). Utility of this vaccine was demonstrated by reduction of lesion severity in NE challenge trails, for example. Also disclosed herein are novel approaches for producing this vaccine in significant quantities. One exemplified approach involves producing NE vaccine (mutated alpha toxin) in bacterial expression systems, preferably utilizing the Pseudomonas fluorescens system, for commercial use in controlling NE in the poultry industry. The subject vaccines can be administered preferably to chickens in several different ways. A novel, Type VI alpha toxin from chicken isolates of Cp is also disclosed.

    摘要: A method for producing a transgenic plant includes providing a nucleic acid molecule comprising at least two regions of nucleic acid sequence that lack sequence homology with genomic DNA of the plant cell, and at least two zinc finger nuclease recognition sites, wherein the at least two regions of nucleic acid sequence that lack sequence homology with genomic DNA of the plant cell flank the at least two zinc finger nuclease recognition sites. A plant cell or tissue having the nucleic acid molecule stably integrated into the genome of the plant cell is transformed. A plant is regenerated from the plant cell. Transgenic plants are produced by the method. Seeds are produced by the transgenic plants.
