Claims
- 1. A method of ameliorating symptoms of a herpes simplex virus associated disease in an animal infected with a herpes simplex virus, said method comprising administering to said animal at least one immunogenic protein from said virus, wherein said protein induces a T Helper Cell type 1 (Th1) response.

a. an increased ratio of virus specific immunoglobulin subclasses reflective of a preferential Th1 response; b. an increased virus specific interferon γ/interleukin-10 (IFNγ/IL-10) ratio; c. increased CD8+ Cytotoxic T Lymphocyte (CTL) levels; and d. increased Interleukin 12 (IL-12) levels.
- 3. The method of claim 2, wherein said increased ratio of virus specific immunoglobulin subclasses is selected from the group consisting of IgG2a/IgG1, IgG1/IgG4, IgG2/IgG4, IgG3/IgG4, (IgG1+IgG2+IgG3)/IgG4, (IgG1+IgG2+IgG3)/IgG5, IgG1/IgE, IgG2/IgE and IgG3/IgE.
- 4. The method of claim 1, wherein said at least one immunogenic protein when administered to a mouse induces a Th1 response comprising an increased ratio of IgG2a/IgG1.
- 5. The method of claim 2, wherein the Th1 response comprises an increased ratio of virus specific immunoglobulin subclasses reflective of a preferential Th1 response, an increased viral specific interferon γ/interleukin-10 (IFNγ/IL-10) ratio, increased CD8+ CTL levels, and increased IL-12 levels, by at least 25% each.
- 6. The method of claim 2, wherein said method results in an increase of the response comprising an increased ratio of virus specific immunoglobulin subclasses reflective of a preferential Th1 response by at least 25%.
- 7. The method of claim 2, wherein said method results in an increased viral specific interferon γ/interleukin-10 (IFNγ/IL-10) ratio, by at least 25%.
- 8. The method of claim 2, wherein said method results in increased CD8+ CTL levels, by at least 25%.
- 9. The method of claim 2, wherein said method results in increased IL-12 levels, by at least 25%.
- 10. The method of claim 2, wherein said animal is a human.
- 11. The method of claim 10, wherein said herpes simplex virus is a herpes simplex virus-2.
- 12. The method of claim 10, wherein said herpes simplex virus is a herpes simplex virus-1.
- 13. The method of claim 11, which comprises administering a composition comprising multiple herpes simplex virus-2 proteins in a pharmaceutically acceptable carrier, but not the ICP10PK protein.
- 14. The method of claim 10, which comprises administration of a virus which comprises the at least one immunogenic protein or which expresses the at least one immunogenic protein following administration.
- 15. The method of claim 14 which comprises administering a herpes simplex virus-2.
- 16. The method of claim 15 which comprises administering the ICP10ΔPK mutant of herpes simplex virus-2.
- 17. The method of claim 1, wherein the at least one immunogenic protein is administered indirectly by administering nucleic acids encoding the at least one immunogenic protein.
- 18. The method of claim 17, wherein said animal is a human.
- 19. The method of claim 18, wherein said viral disease is herpes and wherein said nucleic acid does not encode ICP10PK.
- 20. The method of claim 5, wherein said animal is a human.
- 21. The method of claim 20, wherein said herpes simplex virus is a herpes simplex virus-2.
- 22. The method of claim 20, wherein said herpes simplex virus is a herpes simplex virus-1.
- 23. The method of claim 20, which comprises administration of a virus which comprises the at least one immunogenic protein or which expresses the at least one immunogenic protein following administration.
- 24. The method of claim 21, which comprises administering a composition comprising multiple herpes simplex virus-2 proteins in a pharmaceutically acceptable carrier, but not the ICP10PK protein.
- 25. The method of claim 21, which comprises administering the ICP10ΔPK mutant of herpes simplex virus-2.
- 26. The method of claim 5, wherein the at least one immunogenic protein is administered indirectly by administering nucleic acids encoding the at least one immunogenic protein.
- 27. The method of claim 26, wherein said animal is a human.
- 28. The method of claim 27, wherein said viral disease is herpes and wherein said nucleic acid does not encode ICP10PK.
- 29. A therapeutic vaccine for ameliorating symptoms of a herpes simplex virus associated disease in an animal infected with a herpes simplex virus, said therapeutic vaccine comprising at least one immunogenic protein from the virus, which following administration to the animal induces a response comprising an increased ratio of virus specific immunoglobulin subclasses reflective of a preferential Th1 response, an increased viral specific interferon γ/interleukin-10 (IFNγ/IL-10) ratio, increased CD8+ CTL levels, and increased IL-12 levels.
- 30. The therapeutic vaccine of claim 29, wherein said herpes simplex virus is herpes simplex virus-2 and said at least one immunogenic protein from a herpes simplex virus is from a herpes simplex virus-2.
- 31. The therapeutic vaccine of claim 30, which comprises a herpes simplex virus-2 mutant.
- 32. The therapeutic vaccine of claim 31, wherein said mutant encodes a mutant ICP10 protein which lacks protein kinase activity.
- 33. The therapeutic vaccine of claim 29, said vaccine further comprising an immune stimulant or adjuvant.
- 34. The therapeutic vaccine of claim 29, wherein said herpes simplex virus is herpes simplex virus-1 and said at least one immunogenic protein from a herpes simplex virus is from a herpes simplex virus-1.
- 35. The therapeutic vaccine of claim 34, which comprises a herpes simplex virus-1 mutant.
- 36. A method of identifying an agent which ameliorates a herpes simplex virus associated disease in an animal infected with herpes simplex virus, said method comprising administering a test agent to an animal, analyzing the immune response thereto, and selecting a test agent that induces a Th1 response.
- 37. The method of claim 36, wherein said Thl response comprises an increased ratio of virus specific immunoglobulin subclasses reflective of a preferential Th1 response, an increased viral specific interferon γ/interleukin-10 (IFNγ/IL-10) ratio, increased CD8+ CTL levels, and increased IL-12 levels.
- 38. The method of claim 37, wherein said test agent is selected from the group consisting of a virus, a mutant virus, DNA, a polynucleotide, a protein, a peptide, and mixtures thereof.
