PG - 475-86 AB - Allogeneic hematopoietic stem cell transplantation (allo-SCT) is the treatment of choice for many malignant diseases. It is recognized that the curative potential of allo-SCT relates closely to the immune advantage conferred by allogeneic T-lymphocytes. In allo-SCT donor T-lymphocytes favor engraftment, provide early immune reconstitution, and fight the underlying malignancy--the so-called graft-vs-leukemia (GVL) effect. These benefits are counterbalanced by the occurrence of a life-threatening disease: graft-vs-host disease (GVHD). A suicide gene encodes a protein able to convert a nontoxic prodrug into a toxic product. Therefore, cells expressing the suicide gene become selectively sensitive to the prodrug. The transfer of a suicide gene into donor lymphocytes could allow, upon administration of the prodrug, the in vivo selective elimination of transduced lymphocytes, resulting in the switch-off of GVHD, thus allowing full exploitation of the curative potential of donor T-lymphocytes in the context of allo-SCT. In this chapter the rationale, the materials, and the methods of the suicide-gene strategy with human T-lymphocytes are described.
