Extracorporeal Photopheresis for Specific Immune Tolerance Responses in Heart Transplant Recipients
*Purpose: Extracorporeal photopheresis (ECP) treatment following heart transplantation (HTx) may induce transplant tolerance. A monitoring tool for successful ECP treatment would allow determination of patient-specific…2019 American Transplant Congress
Rcor1 and Regulation of Foxp3+ T-Regulatory Cells In Vitro and In Vivo
Children's Hospital of Philadelphia, Philadelphia, PA
*Purpose: While Foxp3+ T-regulatory (Treg) cells are well established as central players in regulation of allograft acceptance and tolerance, the contributions of several types of…2019 American Transplant Congress
Graft-Infiltrating Regulatory T Cells Are Associated with Long Term Cardiac Xenograft Survival
*Purpose: Regulatory T (CD4+CD25HiFoxP3+) cells (Treg) are a very small subset of CD4+ T cells that have been shown to play an important role in…2019 American Transplant Congress
Tolerogenic Nanoparticles Targeting the Aryl Hydrocarbon Receptor
*Purpose: The aryl hydrocarbon receptor (AHR) has been shown to have a central role in the ability of dendritic cells (DCs) to direct differentiation of…2019 American Transplant Congress
Central Role of Graft Resident Memory T Cells in Pathogenesis of GVHD after Bowel Transplantation
MedStar Georgetown Transplant Institute, Washington, DC
*Purpose: Graft-versus-host disease (GVHD) is a relatively common and highly morbid complication after intestinal transplantation. Its pathophysiology remains poorly understood. Resident memory T cells (TRM)…2019 American Transplant Congress
Human Adenovirus-Specific T Cell Response in Kidney Transplant Recipients Diagnosed with Adenovirus Infection
*Purpose: Cell-mediated immunity plays an important role in controlling human adenovirus (HAdV) infection after kidney transplantation (KT). We investigated T cell lymphocyte subsets and HAdV-specific…2019 American Transplant Congress
Cd45rb Mediates Cd8+T Cell Persistence In An Allogeneic Heterologous Immune Response
Emory Transplant Center, Atlanta, GA
*Purpose: Memory T cells primed with microbial antigen can cross-react with alloantigen and mediate graft rejection, a process termed allogeneic heterologous immunity. Human and murine…2019 American Transplant Congress
The Frequency of Tissue-Resident Donor T and NK Cells in Peripheral Blood after Lung Transplantation is Modulated by Normothermic Ex Vivo Lung Perfusion
*Purpose: The appearance of passenger donor lymphocytes in recipient blood after double lung transplantation has been described decades ago. However, neither their early kinetics, nor…2019 American Transplant Congress
Intact Lymphatics Are Essential for Costimulation Blockade-Induced Lung Allograft Survival
*Purpose: Blocking lymphangiogenesis is thought to diminish immune responses to donor tissues. However, lung transplantation (Tx), which involves airway and vascular but not lymphatic anastomoses,…2019 American Transplant Congress
Bespoke Immunosuppression: Prolonging Transplant Survival through Enhanced T-cell Activation Induced Cell Death
*Purpose: We aim to develop donor-specific immunosuppression by inhibiting T-cell cellular FLICE like inhibitory protein (c-FLIP). Our current work focuses on clinically relevant pharmacological inhibitors…
