CD8+ Foxp3+ Regulatory T Cells Are Induced during Graft-versus-Host Disease and Mitigate Disease Severity

Abstract excerpt

Regulatory T cells (Tregs), in particular CD4(+) Foxp3(+) T cells, have been shown to play an important role in the maintenance of tolerance after allogeneic stem cell transplantation. In the current study, we have identified a population of CD8(+) Foxp3(+) T cells that are induced early during graft-versus-host disease (GVHD), constitute a significant percentage of the entire Treg population, and are present in...
