Claims:
CLAIMS What is claimed is:
1. | A method for inducing lymphoma cell death, the method comprising administering an effective amount of an agent that binds Gb3, such that lymphoma cell death occurs. |
2. | The method of claim 1, wherein the lymphoma cell is a lymphoma cell of B cell origin. |
3. | The method of claim 2, wherein the lymphoma cell of B cell origin is EBV positive. |
4. | The method of claim 1, wherein the agent is a verotoxin. |
5. | The method of claim 4, wherein the verotoxin is selected from the group consisting of verotoxin 1, verotoxin 1 Bsubunit, verotoxin 2, and verotoxin 2c. |
6. | A method for treating a disorder characterized by infiltrating lymphoma cells, the method comprising administering to a subject in need thereof an effective amount of an agent capable of binding Gb3 and inducing the death of the lymphoma cells such that the disorder is treated. |
7. | The method of claim 6, wherein the disorder is lymphoma. |
8. | The method of claim 7, wherein said lymphoma is a cutaneous T cell lymphoma. |
9. | The method of claim 8, wherein said lymphoma is selected from the group consisting of Mycosis Fungoides, sezary syndrome, related cutaneous disease lymphomatoid papilosis, and PTLD. |
10. | The method of claim 9, wherein said lymphoma is PTLD. |
11. | The method of claim 10, wherein said PTLD is associated with renal, heart, lung or liver transplantation. |
12. | The method of claim 6, wherein the agent is a verotoxin. |
13. | The method of claim 12, wherein the verotoxin is selected from the group consisting of verotoxin 1, verotoxin 1 Bsubunit, verotoxin 2, and verotoxin 2c. |
14. | The method of claim 6, wherein the agent is administered in a pharmaceutically acceptable carrier. |
15. | The method of claim 6, wherein the agent is selected from the group consisting of Pag adhesin linked to a toxin and an antibody to Gb3 linked to a toxin. |
16. | The method of claim 15, wherein the toxin is ricin or a ricin derivative. |
17. | The method of claim 6, wherein the subject is human. |
18. | The method of claim 17, wherein said human is HIV positive. |
19. | A kit comprising an agent capable of binding Gb3, such that lymphoma cell death occurs, a container, and instructions for administering said agent such that lymphoma cell death occurs. |
20. | The kit of claim 19 wherein said agent is a verotoxin. |
21. | A method of treating PTLD in a human comprising administering an effective amount of a verotoxin, such that PTLD is treated. |
22. | The method of claim 21, wherein said human is a liver transplant recipient. |
23. | The method of claim 21, wherein said human is a renal transplant recipient. |
24. | The method of claim 21, wherein said human is a heart transplant recipient. |
25. | The method of claim 21, wherein said human is a lung transplant recipient. |
