Abstract:
Methods and compositions are provided herein for non-invasive administration of an adenoviral vector (Ad-vector) vaccine with an adjuvant, such as a TLR3 agonist. These methods provide, for example, an increase in the immune response to the vaccine, an increase in the immunogenicity of the Ad-vector vaccine, an antigen sparing effect and improved safety with an effective protective immune response to the vaccine.
Abstract:
The present invention relates to a receptor-binding ligand either administered intranasally or expressed following intranasal administration from a recombinant vector that expresses at least one therapeutic ligand which binds to a receptor necessary for infection by a respiratory pathogen. The receptor-binding ligand in the respiratory tract not only confers rapid protection as a therapeutic drug but also elicits long-term protective immunity as a vaccine against a respiratory pathogen. This regimen is not compromised by the emergence of drug resistance because the receptor for any pathogen can be blocked by the pathogen's own receptor-binding ligand.
Abstract:
The present invention relates generally to the fields of gene therapy, immunology, and vaccine technology. More specifically, the invention relates to a novel system that can rapidly generate high titers of adenovirus vectors that are free of replication-competent adenovirus (RCA). Also provided are methods of generating these RCA-free adenoviral vectors, immunogenic or vaccine compositions comprising these RCA-free adenovirus vectors, methods of expressing a heterologous nucleic acid of interest in these adenovirus vectors and methods of eliciting immunogenic responses using these adenovirus vectors.
Abstract:
The present invention shows that intranasal administration of E1/E3 -defective adenovirus particles may confer rapid and broad protection against viral and bacterial pathogens in a variety of disease settings. Protective responses lasted for many weeks in a single-dose regimen in animal models. When a pathogen-derived antigen gene was inserted into the El/E3-defective adenovirus genome, the antigen-induced protective immunity against the specific pathogen was elicited before the adenovirus-mediated protective response declined away, thus conferring rapid, prolonged, and seamless protection against pathogens. In addition to E1/E3 -defective adenovirus, other bioengineered non-replicating vectors encoding pathogen-derived antigens may also be developed into a new generation of rapid and prolonged immunologic-therapeutic (RAPIT).
Abstract:
The present invention relates to the decontamination of anthrax spores, prophylaxis and treatment of anthrax infections and, more particularly, to compounds that act as specific inhibitors ofB. anthracis germination/outgrowth-associated proteins, methods and means for making such inhibitors and their use as pharmaceuticals and/or vaccines. The invention also relates to the prophylaxis and treatment of anthrax infections and, more particularly, to vaccines and compositions that comprise B. anthracisantigens, epitopes, proteins, or nucleic acid molecules, including anthrax protective antigen, anthrax lethal factor, anthrax edema factor and anthrax proteins associated with spore germination and outgrowth, as well as methods and means for making such compositions and their use as pharmaceuticals and/or vaccines.
Abstract:
The present invention relates generally to the fields of immunology and vaccine technology. More specifically, the invention relates to recombinant human adenovirus vectors for delivery of avian immunogens and antigens, such as avian influenza into avians. The invention also provides methods of introducing and expressing an avian immunogen in avian subjects, including avian embryos, as well as methods of eliciting an immunogenic response in avian subjects to avian immunogens.

Abstract:
The invention provides an immunogenic composition comprising a GnRH multimer and an antigenic carrier, an immunogenic composition comprising a recombinant vector containing a nucleic acid molecule encoding a GnRH multimer and optionally an antigenic carrier, antibodies elicited by the immunogenic compositions, and methods of using the immunogenic compositions and antibodies for modifying sexual physiology and behavior, improving the organoleptic properties of meat, and treating androgen-dependent prostate tumors and GnRH-sensitive ovarian tumors.
Abstract:
The present invention relates generally to the fields of immunology and vaccine technology. More specifically, the invention relates to mucosal administration via aerosol spray to avians of immunogenic and vaccine compositions, including those comprising recombinant human adenovirus vectors for delivery of genes encoding avian immunogens or antigens, such as genes encoding avian influenza virus. The invention also provides methods and apparatus for use in such administration.
