ABSTRACT
BACKGROUND:
Prolonged persistence of donor-derived T cells after organ transplantation has been proposed to improve long-term allograft survival. However, surviving transplant-derived T cells are also able to mediate devastating graft-versus-host disease (GvHD). Currently, GvHD after organ transplantation is usually refractory to conventional therapy and the disease outcome fatal.METHODS:
Graft-reactive host T cells were generated ex vivo from a patient suffering from a severe and refractory liver-transplant-associated GvHD. To control GvHD, activated alloreactive host T cells were repetitively retransferred into the patient (activated host lymphocyte infusion [aHLI]).RESULTS:
Adoptive transfer of ex vivo activated alloreactive host T cells (aHLI) led to the control and complete resolution of severe GvHD without inducing allograft rejection.CONCLUSIONS:
aHLI opens a novel therapeutic window to control solid-organ transplant-associated GvHD while preserving allograft integrity.
