IL-6R Blockade with Tocilizumab Increases Tregs and Decreases Early Graft Inflammation in Kidney Transplant Recipients: Results of a Randomized Controlled Trial
*Purpose: IL-6, a proinflammatory cytokine and key regulator of Treg/Th17 balance, is strongly associated with renal graft rejection. We hypothesized that IL-6 blockade with tocilizumab…2019 American Transplant Congress
p40 Homodimer Indirectly Induce Proliferation of Endogenous Donor-Reactive Memory CD8 T Cells within High-Risk Allografts via IL-15 Signaling
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: 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…2019 American Transplant Congress
Treg Suppressor Function within Allografts is Required for Tolerance
Surgery, University of Pittsburgh, Pittsburgh, PA
*Purpose: The role of regulatory CD4+Foxp3+ T cells (Treg) suppressor function within allografts in tolerance remains unclear. Thus, we sought to directly address: 1) whether…2019 American Transplant Congress
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…2019 American Transplant Congress
Inhibition of Autophagy Prolongs Recipients Survival through Accelerating CD8+ T Cell Apoptosis in a Rat Liver Transplantation Model
*Purpose: In liver transplantation (LT), acute rejection (AR) remains a common complication that significantly shortens recipient survival although various immunosuppressors have been used in clinical…2019 American Transplant Congress
Clonal Composition And Single-cell Characterization Of T-cell Infiltrates In Cardiac Allograft Vasculopathy
*Purpose: T-cells are implicated in the pathogenesis of cardiac allograft vasculopathy (CAV), yet their clonal composition and function are incompletely defined. We examined the T-cell…2019 American Transplant Congress
Early T Cell Infiltration is Modulated by PD-1/PD-L1 Interactions in Kidney Graft
Inflammation and Immunity, Lerner Research Institute, Cleveland, OH
*Purpose: Allogeneic transplants elicit dynamic T cell responses that are modulated by positive and negative co-stimulatory receptors. We have investigated the impact of PD-1, a…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…
