Poly (ADP-Ribose) Polymerase Inhibitor Treatment Attenuated Renal Ischemia-Reperfusion Injury
H. Jang, K. Lee, J. Jeon, J. Lee, Y. Kim, D. Kim, W. Huh
Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea, Republic of
*Purpose: Robust intrarenal inflammatory responses following ischemia-reperfusion injury (IRI) induce renal injury in ischemic acute kidney injury (AKI). We hypothesized that poly (ADP-Ribose) polymerase (PARP)…

Modulation of Ischemia Reperfusion Injury in Renal Transplantation Using Selective Estrogen Receptor Modulators
P. T. Hernandez¹, C. S. O'Brien¹, S. J. Concors¹, L. N. Krumeich¹, W. Hancock², M. H. Levine¹
¹Hospital of the University of Pennsylvania, Philadelphia, PA, ²Children's Hospital of Philadelphia, Philadelphia, PA
*Purpose: Renal ischemia reperfusion injury (IRI) is a major contributor to delayed graft function (DGF) in kidney transplantation. We previously demonstrated lower rates of DGF…

Oral Administration of Nano-Sized Silicon Particles Regulates Gene Expression Related to Oxidative Stress and Attenuates Rat Renal Ischemia Reperfusion Injury
M. Kawamura¹, R. Imamura¹, Y. Kobayashi², A. Taniguchi¹, S. Nakazawa¹, T. Kato¹, T. Abe¹, H. Kobayashi², N. Nonomura¹
¹Department of Urology, Osaka University Graduate School of Medicine, Suita, Osaka, Japan, ²The Institute of Scientific and Industrial Research, Osaka University, Ibaraki, Osaka, Japan
*Purpose: Organ ischemia reperfusion injury (IRI) is unavoidable in kidney transplantation and induces reactive oxygen species and causes organ damage. Although the effectiveness of hydrogen…

Establishment of Spontaneous Tolerance of Kidney Allografts is Dependent on Mitigation of Ischemia-Reperfusion Injury via the BLTA-HVEM Pathway
Q. Yuan¹, S. Hong¹, E. Szuter¹, Y. Zhao¹, E. Acheampong¹, I. Rosales¹, M. Kronenberg², P. Russell¹, J. Madsen¹, R. Colvin¹, A. Alessandrini¹
¹Massachusetts General Hospital, Boston, MA, ²La Jolla Institute for Allergy & Immunology, La Jolla, CA
*Purpose: Kidney allografts transplanted across certain mouse strain combinations (e.g. DBA/2 to B6) develop tolerance while other combinations do not (e.g. B6 to DBA/2). We…
