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.
