Myeloid Cell-Specific Heme Oxygenase-1 Is Crucial for Hepatoprotection in Liver Ischemia-Reperfusion Injury
K. Nakamura,¹ M. Zhang,² B. Ke,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 and Aim: Heme oxygenase-1 (HO-1), an anti-oxidant enzyme, is essential in tissue resistance against innate immunity driven ischemia-reperfusion injury (IRI). Our group was the…

Damage Associated Molecular Patterns (DAMPs)-Activated Neutrophil Extracellular Trap Formation Exacerbates Liver Ischemia/Reperfusion Injury
H. Huang, S. Tohme, A. Al-Khafaji, A. Tsung.
Department of Surgery, University of Pittsburgh, Pittsburgh, PA.
Liver ischemia/reperfusion (I/R) injury is a clinically important phenomenon encountered during transplantation that contributes to initial graft function and subsequent allograft rejection. Formation of neutrophil…

Macrophage-Specific SIRT1 Regulates HO-1 Mediated Anti-Inflammatory and Cytoprotective Pathways
K. Nakamura,¹ M. Zhang,² B. Ke,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: Sirtuin1 (SIRT1), a NAD+-dependent type III histone/protein deacetylase, is essential for resistance against liver ischemia-reperfusion injury (IRI). We asked whether SIRT1 may affect cytoprotective…

The Impact of Cytokine Release Caused By Induction Immunosupression On Nitric Oxide in Renal transplantation
R. Johns,^1,2 M. Laftsidis,² E. Burrows,² F. Edwards,² E. Ablorsu,² P. James,¹ A. Phillips,^1,2 A. Asderakis.²
¹University of Cardiff, Cardiff, United Kingdom; ²University Hospital of Wales, Cardiff, United Kingdom.
IntroductionVarying induction immunosuppression regimens have a differential impact on the pattern of cytokine release. Pro-inflammatory cytokines stimulate endothelial cells causing secretion of NO. Serum nitrite…
