Prevention of Ischemia Reperfusion Injury (IRI) & ABMR in HLA Sensitized Patients Treated with C1 Esterase Inhibitor (C1INH): Long-Term Follow Up
A. A. Vo, E. Huang, N. Ammerman, J. Choi, I. Kim, A. Peng, R. Najjar, S. Sethi, K. Lim, S. C. Jordan
Cedars Sinai Medical Ctr, Los Angeles, CA
*Purpose: Delayed graft function (DGF) after kidney transplantation is a consequence of IRI/DGF. IRI/DGF requires intense medical management, is costly and predisposes to risk for…

Graft Dendritic Cell p40 Homodimers Activate Donor-Reactive Endogenous Memory CD8 T Cells within Higher Risk Allografts
H. Tsuda, A. Valujskikh, R. Fairchild.
Immunology, Cleveland Clinic, Cleveland, OH.
Memory T cells with donor-reactivity pose a major barrier to successful allograft transplantation and tolerance induction. Longer cold ischemic storage (CIS) prior to transplantation promotes…
