  • Patent number: 8399628
    Abstract: A method of modulating immune response in an animal is disclosed. Such a method interacting the immature dendritic cells from the animal with an antigen ex vivo so that the immature dendritic cells present the antigen on their surfaces, inducing maturation of the immature dendritic cells ex vivo, and contacting the mature dendritic cells ex vivo with a modulator comprising TRANCE, conservative variants thereof, fragments thereof, analogs or derivatives thereof, or a fusion protein comprising the amino acid sequence of TRANCE, conservative variants thereof, or fragments thereof. After contacting the modulator ex vivo, the mature dendritic cells are introduced into the animal. As a result, immune response in the animal towards the antigen is modulated relative to the immune response against the antigen in an animal in which dendritic cells did not interact with the antigen ex vivo, and did not contact a modulator ex vivo.

  • Publication number: 20060257431
    Abstract: This invention relates to methods and compositions useful for delivering antigens to dendritic cells which are then useful for inducing antigen-specific cytotoxic T lymphocytes and T helper cells. This invention also provides assays for evaluating the activity of cytotoxic T lymphocytes. According to the invention, antigens are targeted to dendritic cells by apoptotic cells which may also be modified to express non-native antigens for presentation to the dendritic cells. The dendritic cells which are primed by the apoptotic cells are capable of processing and presenting the processed antigen and inducing cytotoxic T lymphocyte activity or may also be used in vaccine therapies.

  • Publication number: 20060188520
    Abstract: The present invention relates to the identification of a subunit vaccine to prevent or treat infection of Epstein Barr Virus. In particular, EBNA-1 was identified as a vaccine antigen. In a specific embodiment, a purified protein corresponding to EBNA-1 elicited a strong CD4+ T cell response. The responsive CD4+ T cell are primarily TH1 in function. EBNA-1 is an attractive candidate for a protective vaccine against EBV, and for immunotherapy of EBV infection and neoplasms, particularly with dendritic cells charged with EBNA-1.

  • Publication number: 20050282282
    Abstract: This invention relates to methods and compositions useful for delivering antigens to dendritic cells which are then useful for inducing T antigen specific cytotoxic T lymphocytes. This invention also provides assays for evaluating the activity of cytotoxic T lymphocytes. According to the invention, antigens are provided to dendritic cells using a viral vector such as influenza virus which may be modified to express non-native antigens for presentation to the dendritic cells. The dendritic cells which are infected with the vector are then capable of presenting the antigen and inducing cytotoxic T-lymphocyte activity or may also be used as vaccines.

  • Publication number: 20040087532
    Abstract: A method of treating malignancies through induction of immune responses has been found. In one aspect, the present invention is a method for treating malignancy comprising administering an effective amount of a vaccine comprising antigen-presenting cells loaded with at least two or more agents selected from the group consisting of tumor antigens and tumor antigen derived peptides. In another embodiment, the vaccine comprises at least two or more agents selected from the group consisting of tumor antigens and tumor antigen derived peptides which target antigen-presenting cells in the patient. The vaccines can also further comprise antigen-presenting cells loaded with control antigens used to determine the patient's immune competence. The evaluation of vaccine-induced immune responses in blood provides a predictive factor for treatment efficacy.
