  • Patent number: 8106153
    Abstract: Cytotoxic T lymphocytes (CTLs) specific for antigenic peptides derived from IgE molecule can be generated in vitro by stimulating resting naive CD8 T cells with IgE peptides presented by artificial antigen presenting cells. The IgE specific CTLs lyse the target cells loaded with IgE peptides in vitro and inhibit antigen specific IgE response in vivo. In addition, adoptive transfer of the IgE specific CTL to an asthmatic mouse model can inhibit the development of lung inflammation and airway hypersensitivity. IgE specific CTL provides a treatment for allergic asthma and other IgE-mediated allergic diseases. Antigenic peptides identified from non-tumor self-antigens induce specific cytotoxic T lymphocyte (CTL) in vitro. The CTL induced by peptides identified from CD40L can kill activated CD4 T cells. In vitro generated CTL specific for CD40L inhibit CD4-dependent antibody responses of all isotypes in vivo.

  • Patent number: 8075895
    Abstract: Multiple myeloma (MM) is a clonal B cell malignancy and remains essentially incurable by conventional anti-tumor therapy. Patients with MM have a median survival of only three years. MM is characterized by proliferation and accumulation of mature plasma cells in the bone marrow (BM) leading to bone destruction, BM failure, anemia, and reduced immune function. The identification of MHC Class I, HLA-A2, associated peptides presented on multiple myeloma cells is an important step in developing immunotherapies for MM. Presented here are methods for creating activated T lymphocytes that are cytotoxic to both peptide loaded T2 target cells and multiple myeloma cell lines.

  • Patent number: 7993638
    Abstract: In a cancer treatment combining cell therapy with chemotherapy, autologous CD8+ T cells are obtained from a patient, activated ex vivo by contacting them with xenogenic antigen presenting cells loaded with selected peptide antigen, thereby generating antigen-specific activated cytotoxic T lymphocytes. Such activated CTLs are administered to the patient in conjunction with a lymphodepletion and CTL maintenance regimen comprising a non-myeloblative but lymphdepleting agent, such as cladribine or denileukin diftitox, and interleukin-2 and interferon-?-2b stimulatory cytokines.

    Abstract: Methods of processing inactivated artificial antigen presenting cells (aAPCs) and artificial antigen presenting cells with specificity for selected antigenic peptides are described, including their generation and use in cell therapy compositions comprising activated cytotoxic T lymphocytes. Inactivated aAPCs are advantageously generated through crosslinking, such as via a photoreaction involving a psoralen derivative and UVA irradiation.
