摘要:
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.

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:
The present invention utilizes nucleic acid microarray technology to identify changes in the host endothelial cell transcription pattern that occurs during the latent and lytic phase of the KSHV life cycle. The production or activity of some genes up regulated during the lytic cycle were subsequently inhibited, and two such targets were shown to have a role in expression of late viral genes. Using this combined approach we have identified cellular pathways previously unknown to be important for KSHV infection, and present evidence for the efficiency of the novel antiviral approaches thus discovered. In addition, the present invention identifies a wide variety of endothelial cells genes and pathways that are involved in a variety of endothelial cell-mediated activity, including angiogenesis and transformation.
摘要:
CMV vectors comprising a heterologous protein antigen, an active UL131 protein (or an ortholog thereof), and an active UL128 protein (or an ortholog thereof) but lacking an active UL130 protein (or an ortholog thereof) are provided. CMV vectors comprising a heterologous protein antigen, an active UL131 protein (or an ortholog thereof), and an active UL130 protein (or an ortholog thereof) but lacking an active UL128 protein are also provided. In addition, 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 are provided.
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.
