Method for treating or preventing graft versus host disease
A method of treating or preventing graft versus host disease (GVHD) in a subject receiving a graft comprising hematopoietic cells is provided. The method comprises contacting the graft ex vivo with an amount of a Myxoma Virus effective to inhibit proliferation of T lymphocytes in the graft and to treat or prevent GVHD in the host subject following infusion of the graft into the subject. After the contacting of the graft with the Myxoma Virus, the method comprises transplanting the virus-treated graft into the subject.
1. A method of treating or preventing graft versus host disease (GVHD) in a subject receiving a graft comprising hematopoietic cells, the method comprising:
contacting the graft ex vivo with an amount of a Myxoma Virus effective to inhibit proliferation of T lymphocytes in the graft and to treat or prevent GVHD in the subject following transplantation of the graft into the subject; and
after the contacting, transplanting the virus-treated graft into the subject,
wherein the graft comprises an allogeneic graft.
2. The method of claim 1 , wherein the transplanting comprises a technique from the group consisting of an allogeneic hematopoietic cell transplant, a donor cell infusion, and a supportive blood product transfusion.
3. The method of claim 1 , wherein the graft comprises bone marrow or human peripheral blood cells.
4. The method of claim 1 , wherein the T lymphocytes comprise CD3 + T lymphocytes.
5. The method of claim 1 , further comprising
administering at least one of chemotherapy, biotherapy, immunosuppression or radiotherapy to the host subject before transplanting the virus-treated graft into the subject.
6. The method of claim 5 , wherein the graft comprises at least one member from the group consisting of bone marrow and human peripheral blood cells.
7. The method of claim 5 , wherein the subject has a hematologic malignancy.
