Methods for treating GI syndrome and graft versus host disease
We have discovered that administering anti-ceramide antibody treats and prevents an array of diseases mediated by cytolytic T lymphocyte (CTLs)-induced killing and by damage to endothelial microvasculture, including radiation-induced GI syndrome, Graft vs. Host diseases, inflammatory diseases and autoimmune diseases. We have also discovered new anti-ceramide monoclonal antibodies, that have therapeutic use preferably in humanized form to treat or prevent these diseases.
1. A method for treating a disease selected from the group consisting of graft versus host disease, radiation disease, GI syndrome and autoimmune disease in an animal, comprising administering a therapeutically effective amount of an anti-ceramide antibody.
2. The method of claim 1 , wherein the antibody is humanized.
3. The method of claim 2 , wherein the antibody is a monoclonal antibody.
4. The method of claim 3 , wherein the monoclonal antibody is 2A2 IgM.
5. The method of claim 1 , wherein the disease is radiation disease or GI syndrome and the antibody is administered before the animal is exposed to radiation.
6. The method of claim 1 , wherein the disease is graft v. host disease and the antibody is administered before the animal receives a bone marrow transplant.
