MAJOR HISTOCOMPATIBILITY COMPLEX CLASS II-EXPRESSING CANCER CELL VACCINE AND METHODS OF USE FOR PRODUCING INTEGRATED IMMUNE RESPONSES

摘要

Provided are modified cancer cells that are modified to co-express class II trans-activator (CIITA), and an immuno-stimulatory molecule. The immuno-stimulatory molecule is OX-40-ligand or 4-lBB-Ligand. Methods of making the cells are provided by introducing polynucleotides encoding the CIITA and the immune-stimulatory molecule into cancer cells. Methods of stimulating humoral and cell-mediated immune responses by administering the modified cancer cells, or polynucleotides encoding the CIITA and immune-stimulatory molecules are also provided. These approaches can be used to stimulate an immune response against any of a wide variety of cancer antigens.
