摘要:
The present invention includes compositions, methods and kits for enhancing the immunogenicity of an antigen via fusion to a Listerial protein. The present invention further encompasses Listeria vaccine strains for enhancing the immunogenicity of an antigen.
摘要:
The present invention provides DNA vaccines comprising an antibiotic resistance gene-free plasmid, methods of generating same, and methods for treating a disease agent, comprising same.
摘要:
Methods and vaccines for inducing an immune response to a tumor associated antigen in a host are provided wherein the vaccine contains either a fusion protein of the tumor associated antigen fused to a truncated form of listeriolysin or a recombinant form of Listeria monocytogenes which grows and spreads and is capable of expressing the tumor associated antigen alone or as a listeriolysin fusion protein. Methods of suppressing formation of tumors and inhibiting growth of tumors in a host via administration of these vaccines are also provided.
摘要:
Vaccines comprising an attenuated strain of Listeria spp. expressing a selected foreign antigen and methods of eliciting protective immunity by administering an effective amount of the vaccine are provided. The vaccines of the present invention are designed specifically to elicit strong cell-mediated immunity, and are particularly useful for protection in infections which can apparently persist and spread in the presence of neutralizing antibodies invoked by humoral immunity.
摘要:
This invention relates to methods of using a Listeria vaccine vector to induce a Th1 immune response in subjects having persistent Th2 immune response profiles.
摘要:
This invention provides compositions and methods for treating and vaccinating against an Her2/neu antigen-expressing tumor and inducing an immune response against dominant and several sub-dominant epitopes of the antigen.
摘要:
The present invention provides recombinant proteins or peptides comprising a mutated listeriolysin O (LLO) protein or fragment thereof, comprising a substitution or internal deletion of the cholesterol-binding domain or a portion thereof, fusion proteins or peptides comprising same, nucleotide molecules encoding same, and vaccine vectors comprising or encoding same. The present invention also provides methods of utilizing recombinant proteins, peptides, nucleotide molecules, and vaccine vectors of the present invention to induce an immune response to a peptide of interest.
摘要:
The present invention provides methods of treating, protecting against, and inducing an immune response against cervical dysplasia and cancer, comprising the step of administering to a subject a recombinant Listeria strain, comprising a fusion peptide that comprises an LLO fragment and an E7 and/or E6 antigen. 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:
The present invention provides recombinant Listeria strains comprising an angiogenic factor, recombinant polypeptides comprising an angiogenic factor operatively linked to a polypeptide comprising a PEST-like sequence, recombinant nucleotide molecules encoding same, related vaccines, and immunogenic and therapeutic methods utilizing same.
