The Distance Between Us: The Landscape of Recipient-Specific Loss-of-Function in Solid Organ Transplantation and Association with Rejection-Free Graft Survival.
Purpose: This study aims to comprehensively identify genes that are inactivated in both copies in transplant recipients but not in their respective donors, uncovering a…2016 American Transplant Congress
Tracking of Endogenous Graft-Reactive Tregs Reveals Their Peripheral Enrichment During Transplantation Tolerance.
Purpose: Our goal for this study was to determine the relative fates of endogenous Foxp3- conventional (Tconv) and Foxp3+ regulatory T cells (Tregs) specific for…2016 American Transplant Congress
Role of Regulatory T Cells in Induction of Tolerance in Mouse Vascularized Osteomyocutaneous Allotransplantation Under Combined Costimulation Blockade.
Background: The role of regulatory T cells (Tregs) in allograft tolerance has been studied using various transplant models, but the mechanism in vascularized composite allotransplantation…2016 American Transplant Congress
Profiling Metabolic Differences Between Graft- vs. Pathogen-Elicited CD8+ T Cell Responses.
The challenge of immune modulation in transplantation is to inhibit pathologic alloreactivity while minimizing off-target toxicities and preserving protective immunity. Data have emerged demonstrating the…2016 American Transplant Congress
Aquaporin 4 Blockade Is a Novel Strategy to Prevent T Cell Activation and Effector Functions.
1Cleveland Clinic, Cleveland; 2Aeromics LLC, Cleveland.
Aquaporin 4 (AQP4) belongs to the family of integral transmembrane proteins highly permeable to water. We have previously reported that blocking AQP4 with small molecule…2016 American Transplant Congress
Exosomes with Lung Associated Self-Antigens (Collagen V and K alpha 1 Tubulin): Role in Rejection Following Human Lung Transplantation.
Immune response to HLA and non-HLA antigens play a significant role in the development of chronic and acute rejection (AR), bronchiolitis obliterans syndrome (BOS), following…2015 American Transplant Congress
Rejection of an Allograft Through Non-MHC Antigens Does Not Translate to the Rejection of a Different Allograft from the Same Donor in Mixed Chimeras
We previously showed that tolerance, induced by mixed chimerism in mice, is antigen-specific: tolerance of heart and skin allografts is dependent on Foxp3+ cells that…2015 American Transplant Congress
Pretransplant Antibodies Against Angiotensin II Type 1 Receptor in Renal Transplantation: Preliminary Data from the KNOW-KT Study
BackgroundThe antibodies (Abs) against angiotensin II type 1 receptor (AT1R) have been suggested as a risk factor for graft failure and acute rejection. However, incidence…2015 American Transplant Congress
TIM-4 Identifies IL-17 Expressing Pro-Inflammatory Be-17 Cells That Promote Allograft Rejection
Thomas E. Starzl Transplantation Institute, University of Pittsburgh Medical Center, Pittsburgh, PA.
We identified TIM-1 as an inclusive marker for IL-10+ regulatory B cells (TIM-1+ Bregs), which prolong islet allograft survival (GS). We recently found that TIM-4,…2015 American Transplant Congress
Allogeneic Mature Human Monocyte-Derived Dendritic Cells Generate Superior Alloreactive Regulatory T Cells in an IL-2-Independent Manner
IntroductionExpansion of antigen (Ag)-specific natural occurring regulatory T cells (nTregs) is required to obtain sufficient numbers of cells for cellular immunotherapy. In this study, different…
