NFkB Inhibitor Improves Glycemic Control after Syngeneic Islet Transplantation by Suppression of Proinflammatory and Apoptotic Gene Expression in a Cerulein-Induced Pancreatitis Model
G. Yoshimatsu,¹ C. Darden,² K. Kumano,² C. Chang,² P. Saravanan,² M. Lawrence,² B. Naziruddin.³
¹Fukuoka University, Fukuoka, Japan; ²Baylor Scott and White Research Institute, Dallas; ³Baylor Simmons Transplant Institute, Dallas.
Total pancreatectomy with islet autotransplantation (TPIAT) is an effective treatment for refractory chronic pancreatitis. Repeated or continuous pancreatitis attack leads islet damage beyond inflamed exocrine…

Assessment of Immune Cell Profiles in HLA-Sensitized (HS) & Non-HS Patients (Pts) with End Stage Renal Disease (ESRD)
S. Ge,¹ M. Chu,¹ E. Ortiz,¹ A. Vo,² D. Lovato,¹ S. Jordan,² M. Toyoda.¹
¹Transplant Immunology Laboratory, Cedars-Sinai Medical Center, Los Angeles, CA; ²Comprehensive Transplant Center, Cedars-Sinai Medical Center, Los Angeles, CA.
Background: Chronic inflammation is often seen in pts w/ ESRD. HLA-sensitization may create or be driven by the cytokines responsible for chronic inflammation. Here we…

Components of Microvascular Inflammation (MVI) in Kidney Transplant Biopsies (KTxBX) Impacting Late Death Censored Graft Failure (DCGF)
J. Grande,¹ L. Hunsicker,² R. LeDuc,³ A. Matas,³ The DeKAF Consortium.
¹Pathology, Mayo Clinic, Rochester, MN; ²Int. Med., U Iowa, Iowa City, IA; ³Biostatistics and Surgery, U Minnesota, Minneapolis, MN.
Recent studies document that MVI increases DCGF. However, the relationship between components of MVI (Banff scores g, cg, ptc) and macrovascular inflammation (v) have not…

Brain Death Conditions Intensify Inflammation and Impair Metabolic Gene Expression
L. Zitur, P. Chlebeck, S. Odorico, T. Zens, J. Danobeitia, M. Eerhart, J. Reyes, A. D'Alessandro, K. Brunner, S. Capuano, L. Fernandez.
University of Wisconsin, Madison.
Rationale: Inflammation observed in Brain Death (BD) donors is linked to reduced graft function and survival compared to living donors (LD). Detailed analyses of non-human…

Pre-Kidney Transplant Inflammation and Post-Transplant Outcomes.
H. Ying, M. McAdams DeMarco, D. Segev.
Department of Surgery, Johns Hopkins School of Medicine, Baltimore, MD.
Background: Patients with ESRD have higher inflammation levels, which may cause adverse outcomes after they receive a kidney transplant (KT). In this study, we quantified…

Kidney Transplant Rejection is Associated with Robust and Prolonged Bioenergetic Reprogramming and Metabolic Maladaptation
A. Zmijewska, J. Zmijewski, J. Chen, R. Mannon.
Medicine, University of Alabama at Birmingham, Birmingham, AL.
Introduction: Metabolic plasticity and mitochondrial bioenergetic homeostasis are altered due to a organ ischemia. However, the impact of the alloimmune response on the allograft is…
