METHODS AND COMPOSITIONS FOR HYBRID CELL VACCINES FOR THE TREATMENT AND PREVENTION OF CANCER

摘要

The present invention relates to methods for treating and preventing cancer and for treating precancerous lesions by administering a therapeutically effective dose of a vaccine comprising fusion cells formed by fusion of antigen presenting cells and non-dendritic cells that contain genomic DNA or cDNA derived from a tumor cell or a pre-cancerous cell to a cancer patient or patient with a precancerous lesion. In certain embodiments, such vaccines are administered in combination with a cytokine or other molecule that stimulates a cytotoxic T cell (CTL) response and/or a humoral immune response. The present invention also relates to methods for treating and preventing an infectious disease by administering a therapeutically effective dose of a vaccine comprising fusion cells formed by fusion of antigen presenting cells and non-dendritic cells that contain genomic DNA or cDNA derived from the infectious agent that causes the infectious disease to be treated or prevented to a subject. The present invention also related to methods for producing the fusion cells to be used with the methods of the invention. The present invention also provides compositions comprising the fusion cells to be used with the methods of the invention.
