    Abstract: The present invention features incapacitated whole-cell bacterial immunogenic compositions and methods of their production, which compositions are useful to deliver antigens in a manner resembling the live infectious organism in terms of elicitation of a robust immune response, but with reduced risk or no risk of disease. The compositions of the invention are produced by rendering a bacterium bacteriostatic through expression of a recombinant promoter in the bacterial cell, which promoter can be operably linked to a polynucleotide encoding a recombinant gene product. In one embodiment, where the bacterium is a gram negative host, the recombinant gene product provides for reduced toxicity of LPS. In one embodiment, the gene product is a bacteriophage protein, such as endolysin, holin, or ndd.

  • Publication number: 20140141041
    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 E1/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).
