US Patent Application 20090010962 - Genetically Engineered Swine Influenza Virus and Uses Thereof

Claims

1. An attenuated swine influenza virus
comprising a mutation in a swine influenza NS1 gene that diminishes the ability of the NS1 gene product to antagonize the cellular interferon response, and permits the attenuated virus, at a multiplicity of infection of 0.001, to grow to titers between approximately 3 fold to approximately 7 fold lower than wild-type swine influenza in pig cells, as determined approximately 5 days post-infection when propagated under the same conditions.

2. The attenuated swine influenza virus of claim 1, wherein the attenuated virus is genetically engineered.

3. The attenuated swine influenza virus of claim 1, wherein the attenuated virus is a mutagenized virus or reassortant.

4. The attenuated swine influenza virus of claim 2, wherein the attenuated virus is a chimeric virus that expresses a heterologous sequence.

5. The attenuated swine influenza virus of claim 2, wherein the attenuated virus is a chimeric virus that expresses a tumor antigen.

6. The attenuated swine influenza virus of claim 2, wherein the attenuated virus is a chimeric virus that expresses an epitope of a foreign pathogen.

7. The attenuated swine influenza virus of claim 1, wherein pig cells are PK(D1) cells, PK(15) cells, PK13 cells, NSK cells, LLC-PK1 cells, LLC-PK1A cells, ESK-4 cells, ST cells, PT-K75 cells, PK-2a/CL 13 cells or SJPL cells.

8. (canceled)

9. The attenuated swine influenza virus of claim 2, wherein the mutation is a deletion at the carboxy terminus of the NS1 gene.

10. (canceled)

11. An attenuated swine influenza virus comprising a modified NS1 gene, wherein the attenuated swine influenza virus is TX/98/del 126, TX/98/del 99 or TX/98/del 73.

12. An attenuated swine influenza virus having an altered interferon antagonist phenotype, wherein said virus comprises a mutation in the NS1 gene resulting in a deletion of between the 105 carboxy terminal amino acid residues and the 160 carboxy terminal amino acid residues of NS1.

13. The attenuated swine influenza virus of claim 12, wherein the virus is attenuated by a mutation in the NS1 gene resulting in a deletion of all of the amino acid residues of NS1 except amino acid residues 1-95, amino acid residues 1-90, amino acid residues 1-85, amino acid residues 1-80, amino acid residues 1-75, amino acid residues 1-73, amino acid residues 1-70, amino acid residues 1-65, or amino acid residues 1-60, and wherein the amino terminal amino acid is number 1 and the mutation in the NS1 gene confers an altered interferon antagonist phenotype.

14. (canceled)

15. A immunogenic formulation comprising the attenuated swine influenza virus of claim 1, and a physiologically acceptable excipient.

16. A immunogenic formulation comprising the attenuated swine influenza virus of claim 11 or 12, and a physiologically acceptable excipient.

17. A pharmaceutical formulation comprising the attenuated swine influenza virus of claim 1, and a physiologically acceptable excipient.

18. A pharmaceutical formulation comprising the attenuated swine influenza virus of claim 11 or 12, and a physiologically acceptable excipient.

19-20. (canceled)

21. The immunogenic formulation of claim 15, wherein the attenuated swine influenza virus is genetically engineered.

22. The immunogenic formulation of claim 21, wherein the attenuated swine influenza virus is a chimeric virus that expresses a heterologous sequence.

23-26. (canceled)

27. The pharmaceutical formulation of claim 17, wherein the attenuated swine influenza virus is genetically engineered.

28-29. (canceled)

30. The pharmaceutical formulation of claim 27, wherein the attenuated swine influenza virus is a chimeric virus that expresses a tumor antigen.

31. A method for immunizing or inducing an immune response in a pig, comprising administering to said pig an effective amount of the immunogenic formulation of claim 21.

32. A method for immunizing or inducing an immune response a pig, comprising administering to said pig an effective amount of the immunogenic formulation of claim 16.

33. A method of treating a swine influenza virus infection in a pig, comprising administering to said pig an effective amount of the pharmaceutical formulation of claim 27.

34. A method of treating a swine influenza virus infection in a pig, comprising administering to said pig an effective amount of the pharmaceutical formulation of claim 18.

35. A method of treating cancer in a pig, comprising administering to said pig an effective amount of the pharmaceutical formulation of claim 30.

36-40. (canceled)

41. A method for production of an immunogenic formulation comprising:(a) propagating in a substrate the attenuated swine influenza virus of claim 1; and(b) collecting progeny virus,wherein the substrate is a cell, cell line or embryonated egg.

42. A method for production of an immunogenic formulation comprising:(a) propagating in a substrate the attenuated swine influenza virus of claim 11 or 12;(b) collecting progeny virus;wherein the substrate is a cell, cell line or embryonated egg.

43-56. (canceled)

57. A cell containing the attenuated swine influenza virus of claim 1.
