摘要:
A method of engineering a recombinant Listeria vaccine strain to express an HPV antigen, comprising: contacting a Listeria strain auxotrophic for D-alanine synthesis comprising mutations in a D-alanine racemase and a D-amino acid transferase gene in the Listeria's chromosome with a plasmid, the plasmid comprising a first nucleic acid sequence encoding a polypeptide that comprises a human papilloma virus E7 antigen, and a second nucleic acid sequence encoding a D-alanine racemase, wherein the plasmid does not confer antibiotic resistance to the auxotrophic Listeria vaccine strain, whereby the auxotrophic Listeria strain takes up the plasmid and the D-alanine racemase complements the mutation in the D-alanine racemase gene, wherein the auxotrophic Listeria strain grows in the absence of D-alanine, and wherein the first nucleic acid sequence is operably linked to a prokaryotic promoter, thereby engineering a recombinant Listeria vaccine strain to express the HPV antigen.

摘要:
The present invention discloses a process for manufacturing a formulation comprising a drug substance, said drug substance comprising a recombinant Listeria comprising a human papilloma virus (HPV) antigen fused to a Listeriolysin O (LLO) protein fragment. The invention further discloses methods of using treating, protecting against, and inducing an immune response against cervical cancer comprising administration of the recombinant Listeria strain. The present invention also provides methods for inducing an anti-E7 CTL response in a human subject and treating HPV-mediated diseases, disorders, and symptoms, comprising administration of the recombinant Listeria strain.
摘要:
Vaccine compositions for use in inducing enhanced antigen-specific T cell-mediated immune responses in a subject in need thereof are disclosed. The composition comprises (a) a therapeutically effective amount of an immunogenic protein comprising at least an antigen of a pathogen; (b) a saponin-base adjuvant selected from the group consisting of GPI-0100, Quil A, QS-21; and (c) a Toll-like receptor (TLR) agonist adjuvant selected from the group consisting of monophosphoryl lipid A (MPL), and CpG1826.
摘要:
Disclosed herein is a vaccine comprising an antigen and IL-23. Also disclosed herein are methods for increasing an immune response in a subject. The methods may comprise administering the vaccine to the subject in need thereof.
