Abstract: The invention provides a method of activating hepatitis C virus (HCV)-specific T cells, including CD4+ and CD8+ T cells. HCV-specific T cells are activated using fusion proteins comprising HCV NS3, NS4, NS5a, and NS5b polypeptides, polynucleotides encoding such fusion proteins, or polypeptide or polynucleotide compositions containing the individual components of these fusions. The method can be used in model systems to develop HCV-specific immunogenic compositions, as well as to immunize a mammal against HCV.

Abstract: Gene sequences as shown in SEQ ID NO:1-18 have been discovered and isolated, and found to be significantly associated with metastatic spread of breast and colon cancer cells to other organs. Methods are provided for determining the risk of metastasis of a breast or colon tumor, which involve determining whether a tissue sample from a tumor expresses a polypeptide encoded by a gene as shown in SEQ ID NOS:1-18, or a substantial portion thereof. One of the gene sequences encodes a novel aspartyl protease termed CSP56, which can be used to provide reagents and methods for determining which tumors are likely to metastasize and for suppressing metastases of these tumors. Clinicians can use this information to predict which tumors will metastasize to other organs and to provide relevant therapies to appropriate patients.
Abstract: The invention provides polynucleotides encoding Notch receptor ligands, encoded polypeptides, and antibodies specific to the polypeptides. Also provided are methods and compositions for enhancing or inhibiting angiogenesis as well as modulating immune responses.

Abstract: The invention provides a method of treating or preventing a pathologic state in a mammal. The method comprises administering to the mammal a promoter of T-cell expansion and an inducer of CD40 stimulation, wherein CD40 is stimulated on cells of the immune system. The promoter of T-cell expansion and inducer of CD40 stimulation are administered in synergistically effective amounts to treat or prevent the pathologic state in the mammal. The invention also provides a method of assessing the effectiveness of treatment of a pathologic state in a mammal, wherein the mammal has been administered a promoter of T-cell expansion and an inducer of CD40 stimulation, wherein CD40 is stimulated on cells of the immune system.

Abstract: Methods of therapy for treating a subject for multiple myeloma are provided. The methods comprise administering a therapeutically effective amount of an antagonist anti-CD40 antibody or antigen-binding fragment thereof to a patient in need thereof. The antagonist anti-CD40 antibody or antigen-binding fragment thereof is free of significant agonist activity, but exhibits antagonist activity when the antibody binds a CD40 antigen on a human CD40-expressing cell. Antagonist activity of the anti-antibody or antigen-binding fragment thereof beneficially inhibits proliferation and/or differentiation of human CD40 expressing multiple myeloma cells.
