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…

Innate Immune Signaling During Ischemia-Reperfusion Injury in Human Orthotopic Liver Transplantation.
R. Sosa,¹ A. Zarrinpar,² C. Lassman,¹ R. Busuttil,² D. Gjertson,¹ J. Kupiec-Weglinski,¹ E. Reed.¹
¹Pathology and Lab Medicine, University of California-Los Angeles, Los Angeles, CA; ²Surgery, University of California-Los Angeles, Los Angeles, CA.
Background: Orthotopic liver transplantation (OLT) success is hampered by cellular damage elicited by ischemia-reperfusion injury (IRI) which lowers allograft survival. Research using murine models has…

Serelaxin Decreases the Severity of Cold Ischemia-Reperfusion Injury After Liver Transplantation in Mice.
S. Kageyama, K. Nakamura, R. Busuttil, J. Kupiec-Weglinski.
The Dumont-UCLA Transplantation Center, UCLA, Los Angeles, CA.
Background. Extended cold preservation contributes to ischemia-reperfusion injury (IRI), which impairs graft function and leads to poor clinical outcomes. Serelaxin (SER), a recombinant form of…

Allograft TLR4 Receptor Signaling Induces Specific Early Inflammatory Events in Promotes Allografts Subjected to Prolonged Cold Ischemic Storage.
T. Yagisawa, N. Kohei, D. Kish, R. Fairchild.
Dept. Immunology and Glickman Urological Institute, Cleveland Clinic, Cleveland, OH.
Engagement of Toll-like receptors (TLR) by endogenous danger-associated molecular pattern ligands contributes to the intensity of tissue inflammation, including the inflammation generated during ischemia-reperfusion injury…

Strategies to Prevent Ischemic Cholangiopathy After Donation After Circulatory Death Donor Liver Transplantation.
C. Kubal,¹ R. Mangus,¹ J. Fridell,¹ B. Ekser,¹ N. Rush,² R. Saxena,² J. Tector.¹
¹Department of Surgery, Indiana University School of Medicine, Indianapolis, IN; ²Department of Pathology, Indiana University School of Medicine, Indianapolis, IN.
Background: Donation after circulatory death (DCD) donor pool remains underutilized for liver transplantation (LT). We describe optimizing the “modifiable risk factors”, such as CIT, recipient…
