  • Publication number: 20110027321
    Abstract: The present invention provides vaccine compositions useful in prevention and treatment of Chlamydia sp. (e.g., C. trachomatis or C. pneumoniae) infection. Provided are polypeptide vaccine antigens comprising Chlamydia HtrA-derived sequences, including epitopic fragments, analogs, derivatives, and variants. Also provided are a method for inducing an immune response to a subject against Chlamydia infection, a method for preventing Chlamydia infection, or a method for treating a disease or symptom caused by or resulting from infection with Chlamydia, for instance, C. trachomatis or C. pneumoniae. In one embodiment, the present invention is drawn to C. trachomatis HtrA, which induces a cellular immune response and imparts partial protective immunity in vivo.

    Inventors: John H. Kenten, Steven F. Roberts
  • Patent number: 7074620
    Abstract: Method for reducing the level and/or activity of a target protein in a eukaryotic cell via activation of ubiquitination of the target protein wherein the cell is contacted with the compound having a ubiquitination recognition element covalently linked to a target protein binding element. The ubiquitination and recognition element can bind to either the E3 or E2 elements of the ubiquitination system and the target protein binding element is able to bind specifically to the target protein. The target protein binding element has a molecular weight of less than 30,000 and has a binding affinity for the target protein greater than 105M31 1.
