Methods and compositions for treating autoimmune diseases
The invention features methods for increasing or maintaining the number of functional cells of a predetermined type, for example, insulin producing cells of the pancreas, blood cells, spleen cells, brain cells, heart cells, vascular tissue cells, cells of the bile duct, or skin cells, in a mammal (e.g., a human patient) that has injured or damaged cells of the predetermined type.
1. A method for treating or stabilizing a disorder selected from the group consisting of celiac sprue-dermatitis, Crohn's disease, Graves' disease, hypothyroidism, lupus, multiple sclerosis, psoriasis, rheumatoid arthritis, sarcoidosis, Sjogren's syndrome, and ulcerative colitis in a human, said method comprising
administering to said human a tumor necrosis factor-alpha (TNF-alpha) receptor II agonist antibody, wherein said TNF-alpha receptor II agonist antibody selectively kills blood cells with increased sensitivity to cell death, and wherein killing said blood cells treats or stabilizes said disorder.
2. The method of claim 1 , wherein said disorder is celiac sprue-dermatitis.
3. The method of claim 1 , wherein said disorder is Crohn's disease.
4. The method of claim 1 , wherein said disorder is Graves' disease.
5. The method of claim 1 , wherein said disorder is hypothyroidism.
6. The method of claim 1 , wherein said disorder is lupus.
7. The method of claim 1 , wherein said disorder is multiple sclerosis.
8. The method of claim 1 , wherein said disorder is psoriasis.
9. The method of claim 1 , wherein said disorder is rheumatoid arthritis.
10. The method of claim 1 , wherein said disorder is sarcoidosis.
11. The method of claim 1 , wherein said disorder is Sjogren's syndrome.
12. The method of claim 1 , wherein said disorder is ulcerative colitis.
13. The method of claim 1 , wherein said blood cells are T-cells, B-cells, or macrophages.
14. The method of claim 1 , wherein said human already has symptoms of said disorder.
15. The method of claim 1 , wherein said TNF-alpha receptor II agonist antibody is formulated for intramuscular, intravenous, intraperitoneal, intravesicular, intraarticular, intralesional, or subcutaneous administration.
16. The method of claim 1 , wherein said TNF-alpha receptor II agonist antibody is administered in a single dose.
17. The method of claim 1 , said TNF-alpha receptor II agonist antibody is administered in multiple doses.
