Compositions and methods for treating autoimmune and inflammatory diseases
Compositions and methods are provided for the treatment and/or prevention of an inflammatory and/or autoimmune disease or disorder.
1. A method for inhibiting graft versus host disease in a subject in need thereof, said method comprising administering a Crk inhibitor and CrkL inhibitor to said subject,
wherein said inhibitors are inhibitory nucleic acid molecules, and
wherein said method comprises delivering said Crk inhibitor and CrkL inhibitor to cells which are then administered to said subject, wherein said cells comprise hematopoietic stem cells or T cells.
2. The method of claim 1 , wherein said Crk inhibitor inhibits CrkI, CrkII, or both isoforms.
3. The method of claim 1 , wherein said Crk inhibitor and CrkL inhibitor are delivered to said cells in a composition comprising a Crk inhibitor and CrkL inhibitor and at least one pharmaceutically acceptable carrier.
4. The method of claim 1 , wherein said inhibitory nucleic acid molecules are selected from the group consisting of siRNA, shRNA, and antisense molecules.
5. The method of claim 4 , wherein said siRNA or shRNA comprise SEQ ID NO: 1 or SEQ ID NO: 2.
6. The method of claim 1 , wherein said method further comprises administering at least one anti-inflammatory agent.
7. The method of claim 1 , wherein said method further comprises administering at least one immunosuppressant.
8. The method of claim 1 , wherein said cells are allogeneic transplant cells.
9. The method of claim 1 , wherein said cells are allogeneic T cells.
10. The method of claim 1 , wherein said cells are allogeneic hematopoietic stem cells.
11. The method of claim 1 , wherein said subject is undergoing cancer immunotherapy.
12. The method of claim 11 , wherein said cancer is leukemia or lymphoma.
13. The method of claim 11 , wherein said cells are allogeneic hematopoietic stem cells.
14. A method of improving a cancer immunotherapy comprising an allogeneic transplant, said method comprising delivering a Crk inhibitor and CrkL inhibitor to said allogeneic transplant prior to administration to the subject receiving the cancer immunotherapy, wherein said improvement is a reduction in graft versus host disease in said subject,
wherein said inhibitors are inhibitory nucleic acid molecules, and
wherein said allogeneic transplant comprises T cells or hematopoietic stem cells.
15. The method of claim 14 , wherein said cancer is leukemia or lymphoma.
16. The method of claim 14 , wherein said allogeneic transplant comprises hematopoietic stem cells.
17. The method of claim 14 , wherein said allogeneic transplant comprises T cells.
