Abstract: | Efforts to limit graft-versus-host disease (GVHD) mediated by alloreactive donor T cells after allogeneic bone marrow transplantation (allo-BMT) are limited by a concomitant decrease in graft-versus-tumor (GVT) activity and increased possibilities of tumor relapse. Using a novel approach, we adoptively transferred conventional T cells expressing the transcription factor promyelocytic leukemia zinc finger (PLZF), which confers effector properties resembling invariant natural killer T cells (iNKT cells), such as copious production of cytokines under suboptimal stimulation. PLZF expression in T cell allografts attenuates expansion of alloreactive T cells, leading to lower GVHD. Intact alloreactivity-driven antitumor cytokine responses result in preserved GVT effects leading to improved survival. Our findings suggest that therapy with PLZF-overexpressing T cells would result in overall improved outcomes due to less GVHD and intact GVT effects. |
