摘要:
Methods of inducing a CD8+ T cell response to a heterologous antigen in which at least 10% of the CD8+ T cells are MHC-E restricted are disclosed. The method involves immunizing with a CMV vector that does not express UL128 and UL130 proteins. Also disclosed are recombinant CMV vectors comprising nucleic acids encoding a heterologous protein antigen, a UL40 protein, and a US28 protein but that do not express an active UL128 and UL130 protein. Also disclosed are recombinant CMV vectors comprising nucleic acids encoding a heterologous protein antigen, but that do not express an active UL40 protein, UL128 protein, UL130 protein, and optionally a US28 protein. Also disclosed are recombinant CMV vectors comprising nucleic acids encoding a heterologous protein antigen, but that do not express an active US28 protein, UL128 protein, UL130 protein, and optionally a UL40 protein.
摘要:
Disclosed herein are recombinant CMV vectors which may comprise a heterologous antigen that can repeatedly infect an organism while inducing a CD8+ T cell response to immunodominant epitopes of the heterologous antigen. The CMV vector may comprise a deleterious mutation in the US11 glycoprotein or a homolog thereof.

Provided herein are HIV-1 vaccines comprising a carrier and a population episensus antigen determined using the EpiGraph approach. Also provided are HIV-1 vaccines comprising a carrier, a population episensus antigen, and a tailored antigen. Also provided are methods of designing and producing an HIV-1 vaccine for a subject comprising designing vaccine antigens to optimally cover the diversity within a geographic area using an antigen amino acid sequence generated using the EpiGraph approach, and producing said designed vaccine antigen. Also provided are methods of inducing an effector memory T cell response comprising designing the one or more EpiGraph amino acid sequences, producing a vaccine comprising the one or more EpiGraph amino acid sequences and a vector, and administering the vaccine to a subject. Further provided are methods of treating HIV-1 in a subject comprising administering an effective amount of the described HIV-1 vaccines to the subject in need thereof.

Disclosed herein are CMV vectors that include a heterologous protein antigen, an active UL131 protein (or an ortholog thereof), an active UL128 protein (or an ortholog thereof), but wherein the CMV vector lacks an active UL130 protein (or an ortholog thereof). Also disclosed herein are CMV vectors comprising: a heterologous protein antigen, an active UL131 protein (or an ortholog thereof), an active UL130 protein (or an ortholog thereof), but wherein the CMV vector lacks an active UL128 protein. Further disclosed are methods of using CMV vectors to generate an immune response characterized as having at least 10% of the CD8+ T cells directed against epitopes presented by MHC Class II.

This invention also relates to recombinant vectors expressing one or more of the human CMV (HCMV) glycoproteins US2, US3, US6 and US 11 or corresponding functional rhesus CMV (RhCMV) homologues Rh182, Rh184, Rh185 or Rh189, methods of making them, uses for them, expression products from them, and uses for the expression products. This invention also relates to recombinant cytomegalovirus vectors vectors lacking one or more of the glycoproteins, methods of making them, uses for them, expression products from them, and uses for the expression products.
摘要:
Human cytomegalovirus vectors comprising heterologous antigens are disclosed. The vectors derived from the TR strain, are ganciclovir-sensitive, include active US2, US3, US6, US7 and UL131A genes, and have a deleterious or inactivating mutation in the UL82 gene preventing the expression of pp71.

摘要:
Described Herein Are Recombinant Rhesus Cytomegalovirus (RhCMV) And Human Cytomegalovirus (HCMV) Vectors Encoding Heterologous Antigens, Such As Pathogen-Specific Antigens Or Tumor Antigens. The Recombinant Vectors Elicit And Maintain High Level Cellular And Humoral Immune Responses Specific For The Heterologous Antigen. The Recombinant RhCMV And HCMV Vectors May Be Used, For Example, For The Treatment Or Prevention Of Infectious Disease Or Cancer. In Some Examples, The Recombinant RhCMV Or HCMV Vectors May Include Deletions In Genes Encoding Immunomodulatory Proteins. In Some Examples, The Recombinant RhCMV Or HCMV Vectors May Be Deficient Or Impaired In Their Ability To Replicate Within A Cell, Disseminate Within The Host Or Spread Among Hosts By Including A Deletion In One Or More Genes Essential Or Augmenting For CMV Replication, Dissemination Or Spread.
