Vaccine composition comprising methylated DNA and immunomodulatory motifs
The present invention relates generally to compositions and methods using mammalian, dsDNA (Double Stranded Deoxyribonucleic Acid) vaccination for the induction and maintenance of regulator suppressor T cells resulting in suppression of non infectious, and post infectious, inflammatory, allergic, auto-immune, vasculitic, certain degenerative vascular, and graft versus host diseases, with or without the use of IL-10, and with or without the use or TGFβ, with or without the use of anti-IL 6 receptor antibody, anti TNF antibody and or Plasmapheresis, IVIG, Corticosteroids, Methotrexate, Bromocriptine, and or vitamin D analogues.
1. A vaccine composition for treating inflammatory, non infectious and/or post infectious, allergic, autoimmune, vasculitic, degenerative vascular, host v graft, graft v host diseases, Alzheimer's Disease, and amyloidosis comprising:
a suppressor-regulator T cell activating amount of a synthetic, methylated DNA sequence of about 10 k to about 50 k Daltons, containing at least one SEQ ID NO 1 sequence and at least one SEQ ID NO 2 sequence.
2. The vaccine composition, according to claim 1 , wherein said DNA is double-stranded.
3. The vaccine composition, according to claim 1 , further comprising at least one agent selected from the group consisting of cytokines, antibodies, anti-TNF.alpha. biologics, and immunosuppressive agents.
4. The vaccine composition, according to claim 3 , wherein said cytokine is chosen from the group consisting of IL-10 and TGF.beta.
5. The vaccine composition, according to claim 3 , wherein said anti-TNF.alpha. biologics are chosen from the group consisting of Etanercept/Enbrel, Infliximab/Remicade, and Humira.
6. The vaccine composition, according to claim 3 , wherein said immunosuppressive agent is chosen from the group consisting of Corticosteroids, Methotrexate, Bromocriptine, Immuran Cellcept, and vitamin D analogues.
7. A vaccine comprising: a suppressor-regulator T cell activating amount of a synthetic DNA molecule, said DNA molecule further comprising:
At least one methylated region;
at least one SEQ ID NO 1 sequence; and
at least one SEQ ID NO 2 sequence.
