Abstract

The invention provides chimeric proteins and nucleic acids encoding these which can be used to generate vaccines against selected antigens. In one aspect, a chimeric protein comprises an antigen sequence and a domain for trafficking the protein to an endosomal compartment, irrespective of whether the antigen is derived from a membrane or non-membrane protein. In one preferred aspect, the trafficking domain comprises a lumenal domain of a LAMP polypeptide. Alternatively, or additionally, the chimeric protein comprises a trafficking domain of an endocytic receptor (e.g., such as DEC-205 or gp200-MR6). The vaccines (DNA, RNA or protein) can be used to modulate or enhance an immune response against any kind of antigen. In one preferred aspect, the invention provides a method for treating a patient with cancer by providing a chimeric protein comprising a cancer-specific antigen or a nucleic acid encoding the protein to the patient.
