  • Patent number: 8293243
    Abstract: The present invention relates to methods of treating mammals affected by, for example, a hyperproliferative disease such as cancer, by administering a tumor-targeted superantigen and a chemotherapeutic agent, whereby the administration of the tumor-targeted superantigen and chemotherapeutic agent reduce the antibody response and enhance the T cell response. The superantigen, wild-type or modified, is fused to a target-seeking moiety, such as an antibody or an antibody active fragment. The combined administration of a superantigen and a chemotherapeutic agent provides enhanced therapeutic effects in a treated animal.

  • Publication number: 20100166775
    Abstract: A method of identifying a compound for use in therapy which modulates the interaction of S1OO A9 with a ligand comprising: -determining whether a candidate compound is capable of modulating the interaction of S1OO A9 with RAGE or the interaction of S1OO A9 with a TLR (Toll like receptor), or -determining whether a candidate compound is capable of binding to S100A9 in a manner which disrupts binding of S1OO A9 with RAGE or the binding of S100A9 with a TLR, to thereby identify whether the compound may be used in therapy.
