TACI Polymorphisms Associated with Increased Alloimmunity and Allograft Rejection
M. Garcia de Mattos-Barbosa¹, E. A. Farkash², J. L. Platt¹, M. Cascalho¹
¹Transplant Surgery, University of Michigan, Ann Arbor, MI, ²Pathology, University of Michigan, Ann Arbor, MI
*Purpose: Transmembrane activator and CAML interactor (TACI) controls B cell differentiation. The TACI gene is highly polymorphic (>95% of all genes) and frequently variants exhibit…

Desensitization Using Costimulatory Blockade and Bortezomib Does Not Prevent DSA Formation and Rejection in Reconstructive Transplantation
F. Messner¹, Y. Guo¹, R. Chen², Y. Kuo², G. Brandacher¹, B. Oh¹
¹Department of Plastic and Reconstructive Surgery, Johns Hopkins UJohns Hopkins University School of Medicine, Baltimore, MD, ²Division of Plastic Surgery, Kaohsiung Medical Univerity Hospital, Kaohsiung, Taiwan
*Purpose: Sensitiziation in form of donor-specific antibodies (DSA) and subsequent antibody-mediated rejection (AMR) constitute some of the greatest risk factors for allograft rejection and long-term…

Endothelial Cell Cytoskeleton Rearrangement (ECCSKR) and Endothelial to Mesenchymal Transition (EndoMT) in Liver Allografts Following Acute Rejection (AR): Its Significance on the Development of Liver Fibrosis (LF) and Graft Survival
B. H. Ozdemir¹, G. Ozgun¹, E. H. Ayvazoglu Soy², N. Haberal¹, G. Moray², M. Haberal²
¹Pathology, Baskent University, Ankara, Turkey, ²Transplantation, Baskent University, Ankara, Turkey
*Purpose: Endothelial cell (EC) cytoskeleton is critical for EC adhesion and permeability. CSKR initiates permeability and influx of leukocytes which in turn leads to increased…

Kupffer Cells Are Critical for Inflammation Resolution in Liver Ischemia Reperfusion Injury via TIM-4 Mediated Efferocytosis
M. Ni¹, H. Wang¹, D. Jin¹, J. Zhang¹, R. Busuttil¹, J. Kupiec-Weglinski¹, X. Wang², Y. Zhai¹
¹Dumont-UCLA Transplant Center, Los Angeles, CA, ²The First Affiliated Hospital of Nanjing Medical University, Nanjing, China
*Purpose: Liver ischemia reperfusion injury (IRI) remains a clinical problem associated with both surgical and non-surgical settings. Innate immune-dominated inflammation drives the pathogenesis of liver…

Exosomes Carry Stress and Damage Specific miRNAs during Peritransplant Period in TPIAT
P. Saravanan¹, M. Kanak¹, S. Vasu², M. Lawrence², M. Levy¹, B. Naziruddin³
¹Department of Surgery, Virginia Commonwealth University, VCU Health, Richmond, VA, ²Islet Cell Lab, Baylor Scott and White Research Institute, Dallas, TX, ³Simmons Transplant Institute, Baylor Scott and White Medical Center, Dallas, TX
*Purpose: Innate inflammation and hypoxia during peritransplant period significantly affect survival of islet grafts. Markers that can identify stress and/or damage during this early period…

A Prognostic Model to Identify Deceased Donor Kidney Transplant Recipients at High Risk for Delayed Graft Function
S. Kawakita, J. L. Beaumont, M. J. Everly
Terasaki Research Institute, Los Angeles, CA
*Purpose: We have previously identified pre-transplant risk factors for delayed graft function (DGF) in deceased donor kidney transplant (DDKT) recipients and built a machine learning…

Subtyping Of Histologically Stable Kidney Transplants In Molecular Meta-analysis
D. Rychkov¹, T. Sigdel², J. Liberto², M. Sarwal², M. Sirota³
¹ICHS, Department of Surgery, UCSF, San Francisco, CA, ²Department of Surgery, UCSF, San Francisco, CA, ³ICHS, UCSF, San Francisco, CA
*Purpose: Histologically stable allografts have been shown to have molecular inflammation by prior gene expression studies. Nevertheless, there are no methodologies in place to sub-group…
