Referenced literature

In allogeneic stem cell transplantation graft- versus-host disease (GvHD) is one of the most frequent and severe complications.
Data generated from studies in mice have demonstrated that adoptively transferred Treg cells preserve graft-versus-tumor (GvT/L) activity while inhibiting GvHD.

Treg cells, either to the graft or as DLI GvHD alloresponses might be downregulated and though allow at the same time the transfer of more immune effector cells.
