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…
