Abstract excerpt
CD4+CD25+ regulatory T cells (T(regs)) have been shown to inhibit graft-versus-host disease (GVHD) in murine models, and this suppression was mediated by T(regs) expressing the lymphoid homing molecule l-selectin. Here, we demonstrate that T(regs) lacking expression of the chemokine receptor CCR5 were far less effective in preventing lethality from GVHD. Survival of irradiated recipient animals given transplants...
