title: iTreg induced from CD39(+) naive T cells demonstrate enhanced proliferate and suppressive ability.
abstract: CD4(+)CD25(+)FoxP3(+) regulatory T (Treg) cells which consist of naturally occurring Treg (nTreg) and induced Treg (iTreg) cells are associated with the maintenance of immune homeostasis. Previous studies were focused on their potential to ameliorate graft-versus-host disease (GVHD) in human and mice. CD39 is a surface marker both expressed on CD4(+)CD25(-) T cells and Treg cells. CD39(+) Treg cells demonstrate stronger suppressive ability compared to conventional Treg cells. However, whether the potential of CD39(+) naïve T cells induced Treg cells is different from conventional naïve T cells induced Treg cells in vivo and vitro remains to be inconclusive. Here we demonstrate that CD39(+) iTreg cells show enhanced proliferation and suppressive ability as well as lower inflammatory cytokines compared to CD39(-) iTreg cells. To conclude, our findings demonstrate that CD39(+) iTreg cells acquire high suppressive capacity in vitro and vivo, and this may provide a new insight into Treg cell therapy in GVHD clinical trials.
