Immunomodulatory effects of donor lymphocyte infusions following allogeneic bone marrow transplantation

Abstract

Recently, donor lymphocyte infusions have been successfully used to treat patients with CML who have relapsed following allogeneic bone marrow transplantation (BMT). Responses can be achieved in more than 60-70% of patients with stable phase CML without the need for the additional high dose cytotoxic chemotherapy that would accompany a second transplant procedure. The clinical and molecular remissions induced by this approach are a clear demonstration of graft-versus-leukemia (GVL) activity. Although undoubtedly donor lymphocyte infusions are safer than a second BMT, they are associated with toxicities stemming from graft-versus-host disease (GVHD) and pancytopenia. In this review, the immunomodulatory mechanisms underlying the GVL activity of donor allogeneic lymphocytes infusions are presented. Unresolved issues regarding lymphocyte administration are discussed as well as potential ways to limit complications due to GVHD and pancytopenia. New potential applications of this immunotherapeutic approach for treatment of infectious disease and non-hematologic malignancies will be presented.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
