Research Abstract |
In patients receiving allogeneic hematopoietic cell transplantation (HCT), chronic graft-versus-host disease (cGVHD) resembles autoimmune diseases such as systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). In this study, we investigated the function of host T cells on symptoms in cGVHD. CD28-deficient mice as hosts showed an SSc-type cGVHD phenotype; in contrast, WT hosts showed an SLE-type cGVHD phenotype. Adoptive cell transfer experiments demonstrated that defects in host CD4+CD25+ Treg, but not in conventional CD4+ T cells were responsible for phenotypic conversion. Furthermore, the defect of host Treg cells altered the cytokine pattern of donor CD4+ T cells might lead to phenotypic change of cGVHD. Thus, host's CD28 signaling, particularly the pathway that drives Treg development, and host Treg cells played a protective role of the development of SSc-type cGVHD.
