    摘要: The present invention relates to methods for purifying immunogenic, prophylactically and therapeutically effective complexes of modified heat shock proteins noncovalently associated with antigenic peptides of cancer or infected cells. The claimed methods comprise the constructing of a nucleotide sequence encoding a secretable modified heat shock protein, expressing the sequence in an appropriate host cell, recovering the immunogenic complexes from the cell culture and the cells, and purifying the immunogenic complexes by affinity chromatography. Large amounts of such immunogenic complexes can be obtained by large-scale culturing of host cells containing the genetic sequence. The complexes can be used as a vaccine to elicit specific immune responses against cancer or infected cells, and to treat or prevent cancer or infectious diseases.

    摘要: The invention provides a tumor cell genetically modified to express a nucleic acid encoding CD80 (B7.1) and a nucleic acid encoding an HLA antigen. The invention also provides a method of stimulating an immune response to a tumor by administering an allogeneic tumor cell such as a lung cancer cell genetically modified to express a nucleic acid encoding CD80 (B7.1) and a nucleic acid encoding an HLA antigen. The invention additionally provides a method of inhibiting a tumor by administering an allogeneic tumor cell such as a lung cancer cell genetically modified to express a nucleic acid encoding CD80 (B7.1) and a nucleic acid encoding an HLA antigen.

    摘要: Cell-based immunotherapy (e.g., immunization or vaccination) may be improved by frequent administration to a human subject of allogeneic cancer cells secreting a modified heat shock protein (e.g., gp96), depletion of B cells in the subject, or both. Antigen (e.g., epitope derived from neoantigen or tumor antigen of allogeneic or syngeneic cancer cells) may induce a specific immune response in the subject. For example, the epitope bound in an immunogenic complex with the secreted heat shock protein may be obtained from allogeneic cancer cells coexpressing both secreted gp96 and antigen, or from syngeneic cancer cells of the subject expressing only antigen.
