Abstract

Featured are recombinant adenoviruses and vectors thereof. In particular, the adenoviruses are simian (rhesus) adenoviruses having a low seroprevalence and high immunogenicity (when expressing, e.g., an antigenic polypeptide) relative to other adenoviruses and vectors thereof. Also featured are methods for producing the adenoviruses and methods of treatment of diseases by administering the adenoviral vector(s) to a subject (e.g., a human).

First claim

The invention claimed is:

1. A recombinant adenovirus comprising a nucleotide sequence encoding a hexon protein, wherein the nucleotide sequence encoding the hexon protein has at least 93% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67, and wherein the recombinant adenovirus further comprises a deletion in or of the E1, E2, and/or E3 region.

2. The recombinant adenovirus of claim 1 , wherein the nucleotide sequence encoding the hexon protein has at least 94% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

3. The recombinant adenovirus of claim 1 , wherein the hexon protein comprises an amino acid sequence having at least 90% sequence identity to any one of SEQ ID NOs: 159, 162, 163, 165, 166, 168, 169, and 171.

4. The recombinant adenovirus of claim 1 , further comprising a nucleotide sequence encoding at least one fiber protein, wherein the nucleotide sequence encoding the at least one fiber protein has at least 90% sequence identity to all or a part of the nucleic acid sequence of any one of SEQ ID NOs: 17, 18, 22-24, 27-29, 32-35, 38, 39, 41, 43-45, 47, 48, 50, 51, and 53.

5. The recombinant adenovirus of claim 1 , further comprising a nucleotide sequence encoding a penton protein, wherein the nucleotide sequence encoding the penton protein has at least 90% sequence identity to all or a part of the nucleic acid sequence of any one of SEQ ID NOs: 107, 110, 111, 113, 114, 116, 117, and 119.

6. A method of treating a subject having a disease, the method comprising administering the recombinant adenovirus of claim 1 to the subject.

7. A method of inducing an immune response in a subject comprising administering the recombinant adenovirus of claim 1 to the subject.

8. The method of claim 7 , wherein the recombinant adenovirus comprises an antigenic gene product or fragment thereof that promotes an immune response in the subject against an infective agent.

9. A method of producing a recombinant adenovirus comprising:
(i) transfecting a cell with an isolated polynucleotide or complement thereof comprising a nucleotide sequence encoding a hexon protein;
(ii) culturing the cell in a suitable medium to allow replication of the polynucleotide in said cell; and
(iii) harvesting recombinant adenovirus from the cell and/or from the medium, wherein the nucleotide sequence encoding the hexon protein has at least 93% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

10. The recombinant adenovirus of claim 1 , wherein the nucleotide sequence encoding the hexon protein has at least 95% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

11. The recombinant adenovirus of claim 1 , wherein the nucleotide sequence encoding the hexon protein has at least 96% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

12. The recombinant adenovirus of claim 1 , wherein the nucleotide sequence encoding the hexon protein has 97% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

13. The recombinant adenovirus of claim 1 , wherein the nucleotide sequence encoding the hexon protein has at least 98% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

14. The recombinant adenovirus of claim 1 , wherein the nucleotide sequence encoding the hexon protein has at least 99% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

15. The recombinant adenovirus of claim 1 , wherein the nucleotide sequence encoding the hexon protein has 100% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

16. The method of claim 9 , wherein the nucleotide sequence encoding the hexon protein has at least 94% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

17. The method of claim 9 , wherein the nucleotide sequence encoding the hexon protein has at least 96% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

18. The method of claim 9 , wherein the nucleotide sequence encoding the hexon protein has at least 95% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.

19. The method of claim 9 , wherein the nucleotide sequence encoding the hexon protein has at least 97% sequence identity over the entire sequence of any one of SEQ ID NOs: 55, 58, 59, 61, 62, 64, 65, and 67.
