Targeting T-Bet For Prevention Of Graft-Versus-Host Disease And Leukemia Relapse After Allogeneic Hematopoietic Stem Cell Transplantation, Jianing Fu

USF Tampa Graduate Theses and Dissertations

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective therapeutic option for many malignant diseases. However, the efficacy of allo-HSCT is limited by the occurrence of destructive graft-versus-host disease (GVHD). Since allogeneic T cells are the driving force in the development of GVHD, their activation, proliferation, and differentiation are key factors to understanding GVHD pathogenesis. On the other hand, antigen-presenting cells (APCs) are essential for allogeneic T-cell priming and the development of GVHD. The T-box transcription factor T-bet is a master regulator for IFN-γ production and Th1 differentiation. T-bet also regulates the functions of APCs including dendritic cells (DCs) and …
