PD-1+CD3+CD4-CD8- (Double Negative T-cells) Are Early Responders during Kidney Ischemia Reperfusion Injury and Regulated by Non-Classical MHC Molecules
M. Sadasivam, S. Noel, S. Lee, J. Gong, A. Hamad, H. Rabb
Johns Hopkins University and School of Medicine, Baltimore, MD
*Purpose: Unconventional T-cells (e.g. Tregs and γδT-cells) are increasingly recognized for their roles in maintaining homeostasis and protecting non-lymphoid tissues against injury/stress. Double negative (DN)…

Organ Resilience Contributes to Different Impact of Delayed Graft Function (DGF) on Graft Survival in Kidneys Donated by Brain Death (DBD) and Circulatory Death Donors (DCD)
M. J. de Kok, A. F. Schaapherder, L. G. Wijermars, D. K. de Vries, J. L. Lindeman
Transplantation Center, LUMC, Leiden, Netherlands
*Purpose: Despite a tripled higher incidence of DGF in DCD kidney grafts compared to DBD kidney grafts, large studies show equivalent long-term graft survival with…

Distinct Delayed Classical Complement Pathway Activation Highlights Transition of Ischemic Acute Kidney Injury to Chronic Kidney Disease with Interstitial Fibrosis/Tubular Atrophy
S. Kumar, S. Jordan
Comprehensive Transplant Center, Cedars Sinai Medical Ctr, Los Angeles, CA
*Purpose: Ischemia reperfusion Injury (IRI)-induced AKI of the renal allograft frequently leads to delayed graft function (DGF). Patients with DGF suffer from prolonged hospitalization with…
