    摘要: A lymphoma cell line was engineered to express surface IgGl Fc. These tumor cells were taken up rapidly by DCs, leading to enhanced cross-presentation of tumor-derived antigen to CD8 T cells. IgGl-Fc tumors failed to grow in vivo and prophylactic vaccination in an animal model resulted in rejection of unmanipulated tumor cells. Furthermore, IgGl-Fc tumor cells were able to slow the growth of an unmanipulated primary tumor when used as a therapeutic tumor vaccine. This demonstrates that engagement of Fc receptors by tumors expressing the Fc region of IgGl can induce efficient and protective anti-tumor CD8+ T cell responses without prior knowledge of tumor-specific antigen.

    摘要: The invention relates to methods and compositions for causing the selective targeting and killing of tumor cells. Through a combination of ex vivo gene therapy protocols and cell enrichment, tumor cells are engineered to express an α (1,3) galactosyl epitope and optionally the tumor associated antigens mesothelin and carcinoembryonic antigen. After administration of the compositions of the invention to patients, the production of increased antibody titers to certain cell-surface markers, including mesothelin, calreticulin, and carcinembryonic antigen (CEA) positively correlates with an increased overall survival.

    摘要: Methods of treating cancer including administering to a subject with cancer a pharmaceutical composition including an effective amount of a chimeric VSV virus are disclosed. The chimeric viruses are based on a VSV background where the VSV G protein is replaced with one or more heterologous viral glycoproteins. In the most preferred embodiment, the VSV G protein is replaced with the glycoprotein from Lassa virus or a functional fragment thereof. The resulting chimeric virus is an oncolytic virus that is attenuated and safe in the brain, yet still retains sufficient oncolytic activity to infect and destroy cancer cells such glioblastoma, and to generate an immune response against infected cancer cells. Methods of using chimeric viruses as a platform for immunization against other pathogenic microbes are also provided.
