Mechanistic Insights into How Targeting of HDAC10 Promotes Foxp3+ Treg Cell Suppressive Activity, Gene Expression and Metabolism, and Enhances Allograft Survival.
1Children's Hospital of Philadelphia, Philadelphia; 2University of Pennsylvania, Philadelphia.
Foxp3+ T-regulatory (Treg) cells are key regulators of immune responses that can result in unwarranted inflammation and promote allograft rejection. From a theoretical perspective, targeting…2016 American Transplant Congress
The Increase of Serum MiR-142-3p Level in Acute Cardiac Rejection as a Reflection of Exosome-Mediated Genetic Exchange Between T Cells and Endothelial Cells.
1Cardiology, Lund University, Lund, Sweden; 2PROOF Center of Excellence, Vancouver, Canada.
IntroductionIn the recent years, microRNAs has emerged as the popular biomarker candidate in the field of solid organ transplantation due to their expression patterns reflect…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
Profiling of T Cell Subsets in a Primate Cardiac Transplant Model.
Surgery, University of Maryland, Baltimore, MD.
Purpose: Costimulation blockade prolongs graft survival but does not induce tolerance in primates, and mechanisms of rejection are incompletely understood. Here we evaluate changes in…2016 American Transplant Congress
Blockade of the ASC Coreceptor Enhances Hematopoietic Stem Cell Engraftment.
Purpose: HSC engraftment is essential for successful bone marrow transplantation, and successful HSC engraftment allows for induction of tolerance to solid organ allografts. Engrafted HSCs…2016 American Transplant Congress
Tissue Priming of Plasmacytoid Dendritic Cells Enhances Their Phagocytosis and Lowers the Threshold for Subsequent Toll-Like Receptor 7/9 Activation.
Plasmacytoid dendritic cells (pDC) have a pivotal role in clearing viral infections, and can regulate tolerance or immunity depending on their activation status. We have…2016 American Transplant Congress
A Single Histone/protein Acetyltransferase, Tip60, Is Absolutely Essential for Treg Survival and Function, and Its Inhibition Abrogates Induction of Treg-Dependent Allograft Tolerance.
1CHOP & UPenn, Philadelphia, PA; 2Boston University, Boston, MA.
Based on in vitro studies and limited in vivo data from patients with mutations in FOXP3 or animals with depletion of circulating Tregs, Tregs are…2016 American Transplant Congress
Complement Receptor C5aR2 Deletion in Kidney Transplantation in Mice Attenuates Renal Damage.
ObjectiveThe complement receptors C5aR1 and C5aR2 serve distinct roles in immune regulation. In kidney transplantation the early post-implant ischemia reperfusion injury (IRI) causes rapid complement…2016 American Transplant Congress
Dendritic Cells and Damage-Associated Molecular Patterns in Aging.
Recently, it has been shown that Dendritic Cells (DCs) of old organs accelerate graft rejection by orchestrating IL-17A-mediated T cell responses. Moreover, cell-free DNA has…2015 American Transplant Congress
Interleukin-1 Receptor Signaling by Graft Stromal Cells Regulates Donor-Reactive CD8 T Cell Responses to Cardiac Allografts
Allograft reperfusion induces inflammation that directs the infiltration of memory T cells into the allograft and their activation to express functions mediating graft injury. The…
