Phosphoproteomic Analysis of Mouse Hepatic Ischemia/Reperfusion Injury
A. Zarrinpar,² S. Duarte,¹ Y. Lai.²
¹Surgery, University of California, Los Angeles, CA; ²Surgery, University of Florida, Gainesville, FL.
Introduction: Hepatic ischemia/reperfusion injury (IRI) is a major risk factor for acute rejection and early graft dysfunction in liver transplantation. The large and complex landscape…

Inhibition of IL-1R1 Signaling Delays Costimulation Blockade–Resistant Allograft Rejection by Preventing CD8 TEM Expansion
Y. Liu, Y. Dong, D. Mathews, A. Ghosh, A. Adams.
Department of Surgery, Emory University, Atlanta, GA.
The clinical utilization of Costimulaiton Blockade (CoB) led to improved long-term patient outcomes, but wider adoption of is hampered by increased rates of acute cellular…

Endothelial Cell Heterogeneity Governs Basal and Inducible Inflammatory Responses Relevant to Allograft Injury
N. Valenzuela.
Pathology and Laboratory Medicine, UCLA, Los Angeles, CA.
PurposeTransplanted tissues are differentially susceptible to ischemia/reperfusion and rejection. Endothelial cells (EC) are active regulators of inflammation. But model EC may not adequately reflect the…

Pro-Inflammatory B Cells Predict Progressive Minimal Early Renal Allograft Inflammation Which is Associated with Poor Graft Outcomes
A. Sharma, A. Cherukuri, D. Chittka, R. Mehta, S. Hariharan, D. Rothstein.
UPMC, Pittsburgh.
The clinical significance of minimal tubulointerstitial inflammation (MTI:'t'+'i'scores 0.5-1.5) and Banff Borderline changes (BBC:'t'+'i'scores 2-3) in early renal allograft biopsies is unclear. The rate and…
