Enhanced IL-6 Production Impedes Transplant Tolerance Induction in Lupus-Prone Mice.
B. Stocks, C. Wilson, M. Seto, A. Marshall, D. Moore.
Pediatrics and Pathology, Microbiology, and Immunology, Vanderbilt University, Nashville, TN.
Significance: Autoimmunity is a significant barrier to transplantation. Based on previous studies, it is apparent that there are separate genetic regions that control susceptibility to…

Recapitulating Peripheral T Cell Development in Neonatal Mice to Induce Transplant Tolerance.
R. Bascom, K. Tao, L. West.
University of Alberta, Edmonton, Canada.
Purpose: Neonatal mice are susceptible to tolerance induction with semi-allogeneic bone marrow and spleen cells (BMC/SC) while allogeneic BMC/SC cause acute lethal graft-versus-host disease (GVHD).…

Macrophage Specific Deletion of RhoA Impedes Macrophage Functions and Abrogates Chronic Rejection of Cardiac Allograft.
Y. Liu, W. Chen, X. Li, R. Ghobrial, M. Kloc.
Surgery, The Houston Methodist, Houston, TX.
Objective. Chronic rejection of transplanted organs remains the main obstacle in the long-term success of organ transplantation. Chronic rejection occurs in 40-45% of recipients at…

A Novel Humanized Mouse Model Incorporating Non-Fetal Tissue.
M. Brown, I. Norman, Y. Zhou, W. Lou, J. Sullivan, W. Burlingham.
Surgery/Transplant Division, University of Wisconsin-Madison, Madison, WI.
Pre-clinical research into allogeneic tissue transplantation therapies, as well as patient-specific regenerative medicine studies, require animal models that closely mimic the typical patient's immune response.…

TGFb in Regulatory B Cells-Dependent Tolerance.
H. Deirawan, L. Kojima, L. Washburn, J. Markmann, J. Kim.
Surgery, Massachusetts General Hospital, Boston, MA.
In transplantation, increasing evidence support that B cells can play a major regulatory role in addition to their critical functions in allo-immunity and graft rejection.…

HO-1/SIRT1/p53 Axis Regulates Macrophage Activation and Attenuates Liver Ischemia-Reperfusion Injury in Mice.
K. Nakamura,¹ M. Zhang,² B. Ke,¹ S. Kageyama,¹ R. Busuttil,¹ J. Araujo,² J. Kupiec-Weglinski.¹
¹Surgery, Liver Transplant, University of California-Los Angeles, Los Angeles, CA; ²Medicine, Division of Cardiology, University of California-Los Angeles, Los Angeles, CA.
Background/Aim: The mechanism by which macrophage heme oxygenase-1 (HO-1)-Sirtuin1 (SIRT1) signaling promotes resistance against inflammation response in liver ischemia-reperfusion injury (IRI) remains elusive. As tumor…
