Abstract
A composition for genetic manipulation of cells comprises a liposome comprised of lipid material, and adeno-associated viral (AAV) material. Typically, the AAV material is plasmid, and comprises one or more terminal repeats of the AAV genome. Methods are disclosed for introducing DNA into cells using AAV/liposome complexes. The DNA is introduced and expressed in'stem cells, T cells, primary tumor cells, tumor cell lines and dendritic cells or other antigen-presenting cells. Such transfected cells are used in therapeutic methods to treat subjects with cancer or microbial infections. Dendritic cells with DNA encoding tumor or viral antigens and are used to treat subjects with tumors or viral infections by administration in vivo or by activation of antigen-specific lymphocytes ex vivo followed by administration of those lymphocytes to the subject.
