Interruption of OX40L signaling prevents costimulation blockade-resistant allograft rejection.
The potential of costimulation blockade to serve as a novel transplant immunosuppression strategy has been explored for over 20 years, culminating in the recent clinical approval of belatacept for renal transplant patients. Despite improving long-term graft function and survival compared with calcineurin inhibitors, clinical acceptance of belatacept has been hindered by elevated rates of acute ...
متن کاملBlockade of T-cell costimulation prevents development of experimental chronic renal allograft rejection.
Blocking CD28-B7 T-cell costimulation by systemic administration of CTLA4Ig, a fusion protein which binds B7 molecules on the surface of antigen-presenting cells, prevents rejection and induces tolerance in experimental acute allograft rejection models. We tested the effect of CTLA4Ig therapy on the process of chronic renal allograft rejection using an established experimental transplantation m...
متن کاملOX40 costimulation prevents allograft acceptance induced by CD40-CD40L blockade.
Disrupting the CD40-CD40L costimulation pathway promotes allograft acceptance in many settings. Herein, we demonstrate that stimulating OX40 overrides cardiac allograft acceptance induced by disrupting CD40-CD40L interactions. This effect of OX40 stimulation was dependent on CD4(+) T cells, which in turn provided help for CD8(+) T cells and B cells. Allograft rejection was associated with donor...
متن کاملPioglitazone prevents acute and chronic cardiac allograft rejection.
BACKGROUND Peroxisome proliferator-activated receptor-gamma plays an important role in regulating inflammation. Although cardiac transplantation is an established therapy for patients with end-stage heart disease, allograft rejection is a major concern for long-term survival. We investigated the role of pioglitazone in acute and chronic rejection in a murine cardiac transplantation model. MET...
متن کاملAerosol cyclosporine prevents acute allograft rejection in experimental lung transplantation.
BACKGROUND The incidence of acute rejection and the morbidity of systemic cyclosporine (INN: cyclosporine) after lung transplantation is significant. Experimental evidence suggests that the allograft locally modulates the immune mechanisms of acute rejection. The purpose of this study was to determine whether aerosolized cyclosporine would prevent acute cellular rejection, achieve effective gra...
