Differential Impact of Donor and Recipient Age on Post-Lung Transplantation Outcomes
*Purpose: Donor and recipient age at the time of lung transplantation (LTx) have been implicated in poor patient outcomes. The underlying mechanisms driving these effects…2018 American Transplant Congress
Depletion Resistant Effector Memory T Cells Mediate Thymoglobulin Refractory Allograft Rejection in Human Intestinal Transplant Recipients
Medstar Georgetown Transplant Institute, Medstar Georgetown University Hospital, Washington, DC.
A. This study aimed to determine the mechanisms underlying T cell depletion-resistant moderate to severe acute cellular rejection (ACR) in intestinal transplantation (ITx) patients.B. A…2018 American Transplant Congress
Donor Deficiency of RIP3 Phosphokinase Activity Shortens Cardiac Allograft Survival in the Setting of Costimulation Blockade
Surgery, Duke University, Durham, NC.
Receptor-interacting protein kinase 3 (RIP3) is critical for necroptosis in the setting of inflammation. It has been shown that kidney and heart allografts deficient in…2018 American Transplant Congress
Graft Dendritic Cell p40 Homodimers Activate Donor-Reactive Endogenous Memory CD8 T Cells within Higher Risk Allografts
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…2018 American Transplant Congress
VLA-4 Blockade Inhibits Early Endogenous Memory CD8 T Cell Infiltration into Higher Risk Cardiac Allografts and Donor-Reactive T Cell Priming
Endogenous memory CD8 T cells infiltrate MHC-mismatched cardiac allografts within 24 hrs after graft reperfusion in mice. Our recent studies indicate that prolonged cold ischemic…2018 American Transplant Congress
T-bet and STAT6 Double Deficiency Favors IL-17 Immunity after Lung Transplantation
Background: The long-term success of lung transplantation is mainly limited by the development of obliterative bronchiolitis (OB) in which IL-17 plays a critical role. Direct…2018 American Transplant Congress
Single-Cell Analysis of Graft Infiltrating T-Cells in Cardiac Allograft Vasculopathy
Medicine, Columbia University Medical Center, New York, NY.
Background: Cardiac allograft vasculopathy (CAV) remains a leading cause of death after heart transplant.T-cells are thought to play a central role, yet the mechanism by…2018 American Transplant Congress
In Vivo Allograft Exposure to Mitochondrial DAMPs Prior to Organ Procurement Increases Graft Rejection in Mice
Surgery, Duke University, Durham, NC.
Mitochondria released in the setting of tissue injury are a source of damage associated molecular patterns (DAMPs) that initiate innate immune responses. We hypothesized that…2018 American Transplant Congress
p40 Homodimer Induced Proliferation of Endogenous Donor-Reactive Memory CD8 T Cells within High Risk Allografts Requires Memory CD8 T Cell Expression of CD122
Immunology, Cleveland Clinic, Cleveland, OH.
Increasing the duration of cold ischemic storage (CIS) from 0.5 to 8 hrs prior to transplant induces the increased proliferation of endogenous donor-reactive CD4 and…2018 American Transplant Congress
Persistence and Homing of Autologous Donor-Reactive Ex-Vivo Expanded Regulatory T Cells to Heart Allografts in Lymphodepleted Recipient Monkeys
Surgery, Starzl Transplantation Institute, Pittsburgh, PA.
Background:Infusion of ex vivo expanded regulatory T cells (Treg) is a promising therapy to prevent allograft rejection. Trafficking of Treg to allografts and secondary (2ry)…
