MTOR Inhibition Acts Directly on Endothelial Cells to Induce Contact-Independent Immune-Modulation of Allo-Specific T Cell Activation
H. Xu, L. Wang, V. A. Bendersky, Q. Gao, Q. Li, A. D. Kirk, H. Xu
Duke University School of Medicine, Durham, NC
*Purpose: Endothelial cells (ECs) form a barrier between vascularized organ allografts and host immunity and are known to provoke alloimmune responses. The mTOR inhibitor rapamycin…

Renal Preservation with Belatacept-Based versus Everolimus-Based Immunosuppression in Lung Transplant Recipients
E. Sartain¹, K. Schoeppler¹, B. Crowther¹, J. Smith², A. Gray²
¹University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences, Aurora, CO, ²Department of Medicine, Division of Pulmonary Sciences and Critical Care, University of Colorado, Denver, CO
*Purpose: Renal dysfunction is one of the most common long-term complications among lung transplant recipients (LTRs). Calcineurin-inhibitor (CNI) nephrotoxicity is a recognized contributor to renal…

Belatacept and Rapamycin Maintenance Immunosuppression in a Sensitized Nonhuman Primate Kidney Allotransplantation Model
R. Schmitz¹, Z. W. Fitch¹, M. Manook¹, J. Yoon¹, A. B. Farris², J. Kwun¹, S. J. Knechtle¹
¹Department of Surgery, Duke University Medical Center, Durham, NC, ²Department of Pathology and Laboratory Medicine, Emory University School of Medicine, Atlanta, GA
*Purpose: Desensitization with costimulation blockade and proteasome inhibition prior to kidney transplantation prevents early antibody-mediated rejection (AMR) and prolongs graft survival in highly sensitized nonhuman…

Torc1 Inhibition Protects Activated Human Regulatory T Cells from Self-Inflicted Damage via Granzyme B
J. B. Alhaddad, H. Allos, B. S. Al Dulaijan,, S. K. Eskandari, I. Sulkaj, G. Melhem, J. Y. Choi, J. R. Azzi
Transplantation Research Center, Brigham and Women's Hospital, Harvard Medical School, Boston, MA
*Purpose: The use of Regulatory T cells (Tregs) in adoptive cell therapy has been hindered by their short survival following their adoptive transfer. We have…

MTOR-Inhibitor Regimens and Malignancy after Kidney Transplantation: Can the Risk Be Modified by Considering Human Leukocyte Antigen (HLA) Mismatch in Immunosuppression Selection?
A. Santos¹, C. Chen¹, K. Alquadan², M. A. Leghrouz², X. Wen³
¹University of Florida, Gainesville, FL, ²Division of Nephrology, Hypertension, & Renal Transplantation, University of Florida, Gainesville, FL, ³Department of Pharmacy Practice, University of Rhode Island, Kingston, RI
*Purpose: We investigated the outcomes of mammalian target of rapamycin inhibitor (MTORI) regimens in adult kidney transplant (KT) recipients (KTRs) in categories of donor/recipient pre-transplant…
