Cmv Infection Sensitizes Transplant Recipients by Promoting Alloreactive T Cell Response
S. Yu, A. Dangi, X. Luo
Nephrology/Medicine, Duke University, Durham, NC
*Purpose: Cytomegalovirus (CMV) infection has been associated with allograft rejection in immunosuppressed transplant recipients. We have previously shown that acute CMV infection impairs the induction…

Sensitization via Pregnancy Generates Alloantibody and Cross-Reactive Xeno-Antibody in a Non-Human Primate Model
J. Yoon, M. Manook, Z. Fitch, R. Schmitz, A. Choi, A. M. Jackson, S. Knechtle, J. Kwun
Surgery, Duke University, Durham, NC
*Purpose: Women are disproportionately represented among highly sensitized waitlist candidates and within HLA-incompatible transplantation programs. Due to difficulties obtaining compatible donors, sensitized patients are seen…

Kidney Paired Donation Outcomes among High PRA Recipients
A. Thomas¹, A. Shaffer², M. Henderson², D. Segev²
¹University of North Carolina, Chapel Hill, NC, ²Johns Hopkins, Baltimore, MD
*Purpose: Kidney paired donation (KPD) accounts for an increasing amount of living donor transplants in the US. Previous studies have shown equivalent outcomes between transplants…

Possible Mechanism of Sensitization against Angiotensin Type II Receptor after LVAD Implantation
P. Kimball¹, V. Chau², F. McDougan¹, M. Flattery², K. Shah²
¹Surgery, VCUHS, Richmond, VA, ²Cardiology, VCUHS, Richmond, VA
*Purpose: Detection of antibody (Ab) against angiotensin-II receptor (AT1R) following VAD implantation portends poorer outcomes for heart transplantation (HT). However, the cause of this sensitization…
