    摘要: Provided herein are recombinant fusion polypeptides comprising one or more antigenic peptides (e.g., fused to a PEST-containing peptide) from cancer-associated proteins. The antigenic peptides can comprise one or more or all of an antigenic peptide comprising a recurrent cancer mutation, an antigenic peptide comprising a heteroclitic mutation, or an antigenic peptide fused to a ubiquitin protein. For example, provided herein are recombinant fusion polypeptides comprising two or more antigenic peptides (e.g., fused to a PEST-containing peptide), wherein each antigenic peptide comprises a recurrent cancer mutation, and wherein at least two of the antigenic peptides are fragments of the same cancer-associated protein. Also provided are nucleic acids encoding such fusion polypeptides, recombinant bacteria or Listeria strains comprising such fusion polypeptides or such nucleic acids, and cell banks comprising such recombinant bacteria or Listeria strains. Also provided herein are methods of generating such fusion polypeptides, such nucleic acids, and such recombinant bacteria or Listeria strains. Also provided are immunogenic compositions, pharmaceutical compositions, and vaccines comprising such fusion polypeptides, such nucleic acids, or such recombinant bacteria or Listeria strains. Also provided are methods of inducing an anti-tumor-associated-antigen immune response in a subject, methods of inducing an anti-tumor or anti-cancer immune response in a subject, methods of treating a tumor or cancer in a subject, methods of preventing a tumor or cancer in a subject, and methods of protecting a subject against a tumor or cancer using such recombinant fusion polypeptides, nucleic acids, recombinant bacteria or Listeria strains, immunogenic compositions, pharmaceutical compositions, or vaccines.

    摘要: This invention provides methods and compositions for using evaluating biomarker expression in a disease and providing a multi-targeted Listeria-based immunotherapeutic approach against said disease. In a related aspect, the invention relates to a method of treating a disease in a subject, the method comprising the steps of: a. obtaining a biological sample from said subject; b. evaluating the expression of a predetermined number of biomarkers in said biological sample; c. administering to said subject a composition comprising a recombinant Listeria strain, said strain comprising a nucleic acid sequence encoding at least one fusion protein, wherein said fusion protein comprises a biomarker identified in said biological sample, wherein said biomarker is associated with said disease, wherein said biomarker is fused to a PEST-containing polypeptide, and wherein each fusion protein within said Listeria comprises a different biomarker, thereby treating said disease in said subject.
