  • Patent number: 8133972
    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.

  • Publication number: 20120052504
    Abstract: A method of screening a subject for a proliferative disease risk factor comprises detecting the presence or absence of upregulation of the CLN3 gene in the subject. The upregulation of the CLN3 gene in the subject indicates the subject is at increased risk of developing a proliferative disease. Methods of screening compounds for the treatment of proliferative diseases based on the CLN3 gene and its product are also disclosed, along with methods of treating such diseases and vectors useful therefore.

  • Publication number: 20120045829
    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.
