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:
Methods and compositions are provided for lyophilization of bacteria or Listeria strains, such as Listeria monocytogenes. Provided are methods for producing a lyophilized composition comprising a bacteria or Listeria strain, formulations for lyophilization comprising a bacteria or Listeria strain, lyophilized bacteria or Listeria strains, and methods of preparing frozen bacteria or Listeria strains for lyophilization.
摘要:
Methods and compositions are provided for assessing attenuation and/or infectivity of bacteria or Listeria strains, such as Listeria monocytogenes.
摘要:
The subject matter described herein is directed to methods of treating, protecting against, and inducing an immune response against a human papillomavirus-associated tumor or cancer, comprising the step of administering to a subject a recombinant Listeria strain expressing a construct comprising at least one human papillomavirus antigen in combination with one or more other therapeutic agents to treat a tumor or metastatic cancer.
摘要:
This disclosure provides compositions, including Listeria delivery vectors comprising minigene expression constructs, and methods of using the same for inducing an immune response against an antigen-expressing tumor and for treating the same, and vaccinating against the same in subjects bearing the tumors.

摘要:
Provided herein are recombinant Listeria strains expressing a tumor-specific antigenic polypeptide and, optionally, an angiogenic polypeptide wherein a nucleic acid molecule encoding at least one of the polypeptides is operably integrated into the Listeria genome in an open reading frame with a nucleic acid sequence encoding a PEST-containing polypeptide, methods of preparing same, and methods of inducing an immune response, and treating, inhibiting, or suppressing cancer or tumors comprising administering same.
摘要:
The present disclosure provides methods of treating, protecting against, enhancing and inducing an immune response against a tumor or cancer, comprising the step of administering to a subject a recombinant Listeria. In other embodiments, the Listeria stimulates the STING pathway.
