Graft-versus-host disease: a surge of developments

Stanley R Riddell et al. PLoS Med. 2007 Jul.

Abstract

Stanley Riddell and Frederick Appelbaum review progress in preventing graft-versus-host disease following allogeneic hematopoietic cell transplantation for malignancies or other life-threatening blood diseases.

Figure 3. Selective Manipulation of T Cell Subsets in Allogeneic Stem Cell Grafts to Reduce GVHD while Retaining GVT and Pathogen-Specific Immunity
Strategies being developed to modify the T cell content of allogeneic stem cell grafts include: a) depletion of the TN subset of cells that contain the repertoire of T cells capable of recognizing minor histocompatibility antigens expressed on skin, gastrointestinal, and hepatic tissues; b) expanding TREG cells that interfere with activation of alloreactive T cells to augment the stem cell graft; c) isolation and expansion of tumor-reactive T cells from naïve T cell progenitors for adoptive immunotherapy to augment the GVT effect; and d) retention of TM cells in the graft to restore protective T cell immunity to pathogens.
