Induction of Major Histocompatibility Complex-mismatched Mouse Lung Allograft Acceptance With Combined Donor Bone Marrow: Lung Transplant Using a 12-Hour Nonmyeloablative Conditioning Regimen.

ABSTRACT:

Background

Despite broad and intense conventional immunosuppression, long-term survival after lung transplantation lags behind that for other solid organ transplants, primarily because of allograft rejection. Therefore, new strategies to promote lung allograft acceptance are urgently needed. The purpose of the present study was to induce allograft tolerance with a protocol compatible with deceased donor organ utilization.

Methods

Using the major histocompatibility complex-mismatched mouse orthotopic lung transplant model, we investigated a conditioning regimen consisting of pretransplant T cell depletion, low-dose total body irradiation and posttransplant (donor) bone marrow, and splenocyte infusion followed by posttransplantation cyclophosphamide.
