Ex Vivo Isolated Human Vessel Perfusion System for the Design and Assessment of Nanomedicines Targeted to the Endothelium
L. G. Bracaglia¹, T. Lysyy², L. Qin², C. Albert¹, J. S. Pober², G. Tellides², W. M. Saltzman¹, G. T. Tietjen²
¹Yale University, New Haven, CT, ²Yale School of Medicine, New Haven, CT
*Purpose: In solid organ transplantation the host immune system acts to reject the graft. This process is facilitated at the endothelial surface, where inflamed donor…

IL-10 Signaling in T Cells is Essential for Induction of Transplant Tolerance
M. Iglesias Lozano, D. Bibicheff, M. Chicco, G. Brandacher, G. Raimondi
Plastic Surgery, Johns Hopkins University, Baltimore, MD
*Purpose: Induction of long term transplant survival by “costimulation blockade” (CoB) is achieved through deletion of abortively activated alloreactive T cells and generation of graft…

Single-Cell RNA Sequencing to Assess the Effect of IL-6 Receptor Blockade in Kidney Transplantation
A. Zarinsefat, P. Rashmi, A. Da Silva, T. Sigdel, S. Chandran, Q. Tang, J. Ye, F. Vincenti, M. Sarwal
University of California San Francisco, San Francisco, CA
*Purpose: Prospective randomized study of IL-6R blockade with Tocilizumab for treatment of subclinical inflammation (SCI) in renal transplantation, reveals unique profiles of resting and stimulated…

Time-Zero Histology Correlates with Donor Characteristics but Does Not Predict Short-Term Outcomes in Kidney Transplantation
S. Raza, G. Agarwal, D. Anderson, M. Deierhoi, H. Fatima, M. Hanaway, J. Locke, P. MacLennan, B. Orandi, C. Young, R. Mannon, M. Seifert
University of Alabama School of Medicine, Birmingham, AL
*Purpose: Time-zero biopsies provide important information about baseline histology but their clinical utility compared to other non-invasive predictors is unclear. Our center performs universal time-zero…

Mitochondrion-Endothelial Interaction Generates Danger Signal in Promoting Costimulation-Resistant T Cell-Mediated Allograft Rejection
S. Li¹, M. Song¹, Q. Li², A. Kirk¹, H. Xu¹
¹Surgery, Duke University, Durham, NC, ²Immunology, Duke University, Durham, NC

Cell-Free DNA (cfDNA) is Released by Necroptosis and Promotes Kidney Ischemia Reperfusion Injury
A. C. Dionne
Microbiology and Immunology, Western University, London, ON, Canada
