CD4 T Cell Depletion Mitigates Ischemic Hepatocellular Damage and Promotes Immune Regulation in Mouse Liver Allografts.
S. Kageyama, K. Nakamura, R. Busuttil, J. Kupiec-Weglinski, Y. Zhai.
The Dumont-UCLA Transplant Center, Department of Surgery, David Geffen School of Medicine at University of California, Los Angeles, CA
Background: Extended cold preservation contributes to organ ischemia-reperfusion injury (IRI), which stimulates host allo-reactivity, leading to inferior clinical outcomes. We have shown that CD4+ T…

Donor Genetic Background Determines the Severity of Delayed Graft Function Following Kidney Transplantation in Mice.
L. Qiu, J.-J. Wang, X. Yeap, Z. Zheng, M. He, M. Abecassis, Z. Zhang.
Comprehensive Transplant Center, Department of Surgery, Northwestern University Feinberg School of Medicine, Chicago, IL
Background: Delayed graft function (DGF) has been associated with poor clinical transplant outcomes. Current mouse models of kidney transplant or acute kidney injury induced by…

ASC-Deficient Dendritic Cells Exhibit Activation Defects and a Reduced Ability to Stimulate Allogeneic T Cells.
A. Scheinok, A. Shigeoka, S. Kasimsetty, R. Elahimehr, D. McKay.
Medicine, University of California-San Diego, La Jolla, CA.
Donor dendritic cell (DC) activation causes adaptive immune responses that lead to rejection of transplanted allografts. Accumulating data suggest that inflammasome assembly within interstitial DCs…

Reducing Non-Anastomotic Biliary Strictures After Donation After Circulatory Death Liver Transplantation, a Matter of Time?
N. Gilbo, I. Jochmans, M. Sainz, J. Pirenne, D. Monbaliu.
Abdominal Transplantation Surgery, KU Leuven, Leuven, Belgium.
Liver Transplantation (LT) from donation after circulatory death (DCD) is associated with increased non-anastomotic biliary strictures (NAS) and graft loss. Donor and recipient demographics, transplant…

Cold Storage Stabilization of Gap Junctions Reduces Post Transplant Ischemia Reperfusion Injury.
R. Finnegan,¹ P. Zhu,¹ S. Stephenson,¹ K. Patel,² S. Nadig,^1,2,3 C. Atkinson.^1,2,3
¹Department of Microbiology and Immunology, Medical University of South Carolina, Charleston, SC; ²Department of Surgery, Medical University of South Carolina, Charleston, SC; ³South Carolina Investigators in Transplantation, Medical University of South Carolina, Charleston, SC.
Purpose: Organ procurement, cold storage and ischemia reperfusion injury (IRI) promote inflammation, which induces endothelial cell (EC) activation and dysfunction post transplantation. EC gap junctions…
