Disclosed are methods for treating or limiting development of diabetes, by transplanting into the eye of a subject with diabetes or at risk of diabetes an amount effective to treat or limit development of diabetes of insulin-producing cells engineered to reduce expression of a β3 subunit of Cav (Cavβ3).

In one aspect, the embodiments disclosed herein relate to the production of fully-deleted adenovirus-based gen delivery vectors packaged without the use of an adenoviral helper virus, and more particularly in their use in the transfer of genes and the expression of proteins, vaccine development, and cell engineering. In another aspect, the production of adenoviral vectors deleted of all adenoviral genes is described that carry genes of interest with detrimental or toxic activities to eukaryotic cells.

The present disclosure relates to recombinant human adenoviruses engineered to express a structural protein of a coronavirus. The recombinant adenoviruses are suitable for active immunization against a coronavirus in a human subject. Additionally, immune globulin obtained from immunized human subjects is suitable for passive immunization of a coronavirus-infected human subject.

Disclosed herein are self-replicating RNA molecules encoding prostate neoantigens, vaccines, and method of treating and preventing prostate cancer using the self-replicating RNA molecules and vaccines.

The present disclosure includes compositions and methods for treating cancer, such as bladder cancer.

Compositions and methods for treating a viral infection may comprise use of an adenoviral vector. An adenoviral vector of the present disclosure may comprise a non-human adenoviral genome with one or more gene locus functionally removed and a transgene. A method of treating a viral infection may comprise administering a composition comprising an adenoviral vector of the present disclosure, to a subject and reducing the infectivity or transmission of the virus. Intranasal administration provides enhance protection of the upper respiratory tract of a subject relative to intramuscular administration.

The invention relates to an expression system comprising polynucleotides encoding proteins, wherein the expression system comprises a first polynucleotide encoding at least one protein, peptide or variant thereof, which induces a T cell response, and a second polynucleotide encoding at least one protein, peptide or variant thereof, which induces an anti-pathogenic B cell response. The invention further relates to protein mixtures encoded by the expression system and cells comprising the expression system or the protein mixture and pharmaceutical compositions comprising the expression system or the protein mixture.

This disclosure provides replication-incompetent adenoviral vectors useful in vaccine development and gene therapy. The disclosed vectors comprise a selective deletion of E3 and are particularly useful for preparation of vaccines development and for gene therapy using toxic transgene products that result in vector instability that occurs when the entire E3 domain is deleted.

The present invention relates to isolated polynucleotide and polypeptide sequences derived from novel chimpanzee adenovirus ChAd157, as well as to recombinant polynucleotides, vectors, adenoviruses, cells and compositions comprising said polynucleotide and polypeptide sequences.

Disclosed herein are compositions that include antigen-encoding nucleic acid sequences and/or antigen peptides. Also disclosed are nucleotides, cells, and methods associated with the compositions including their use as vaccines, including vectors and methods for a heterologous prime/boost vaccincation strategy.
