Tissue Resident Memory T Cells in Murine Renal Transplantation
Starzl Transplantation Institute, Pittsburgh, PA
*Purpose: The newly identified tissue resident subset of memory T cells (TRM) provides immune surveillance in the tissue and first response against infections. They are…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
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
Multiplexed Droplet Single-Cell RNA-Sequencing for Cellular Profiling of Transplant Rejection
Department of Surgery, UCSF, San Francisco, CA
*Purpose: Multiplexed droplet single-cell RNA-sequencing (mdscRNA-seq) has been utilized across many tissue types for fast and paralleled transcriptomic profiling. However, maintaining sample identity for differential…2019 American Transplant Congress
The Impact of Biological Behavior of Allograft Infiltrating Lymphocytes during Early Phase
Gastroenterological Surgery I, Hokkaido University, Sapporo, Japan
*Purpose: The graft infiltrating lymphocytes (GILs) build an immunological microenvironment locally. Reportedly the GILs within 72hrs posttransplantation do not attack allograft, but may prevent from…2019 American Transplant Congress
Increased Number of Intragraft FoxP3+ T Cells is Strongly Correlated with Decreased Graft Survival in Chronic Active Antibody Mediated Rejection
1Erasmus MC, Rotterdam, Netherlands, 2Amsterdam UMC, Amsterdam, Netherlands
*Purpose: Chronic-active antibody-mediated rejection (c-aABMR) is the most important cause of late renal allograft failure. However, renal inflammation and rate of loss of renal allograft…2019 American Transplant Congress
Cellular And Molecular Characteristics Of Intra-graft Lymphoid Aggregates In Chronic Lung Allograft Dysfunction
*Purpose: Lymphoid aggregates (LAs) have been identified within lung allografts post lung transplant (LTx). However, it remains controversial whether they represent benign lymphoid tissue or…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
Endoplasmic Reticulum Stress Sensor IRE1α Deficiency Promotes Infiltrating Macrophage Polarization and Induces Long-Term Renal Allograft Acceptance in Mice
Objective: Macrophage is involved in the pathogenesis of I/R injury and allograft rejection. However, the mechanisms underlying this is vastly unknown. This study aims to…2018 American Transplant Congress
Identification of Anti-Inflammatory and Pro-Inflammatory Gut Microbiota That Determine Graft Survival
Introduction: The gut microbiota induce and train the host immune system. Whether microbiota from contrasting environments of colitic or pregnant mice are pro- or anti-inflammatory…
