Integrative Analysis of Immune Repertoire and Gene Expression from RNA-seq in Kidney Organ Transplants
*Purpose: The main problem with kidney transplantation is the possibility of rejection, which is classified as either antibody-mediated rejection (AMR) or T-cell-mediated rejection (TCMR) depending…2019 American Transplant Congress
IE-1 Specific T Cell Receptor Repertoire Diversity and Protection against CMV Reactivation
*Purpose: Cytomegalovirus (CMV) is a major complication for organ transplant recipients. T cells reacting to the CMV antigen immediate-early (IE-1) are key in controlling reactivation…2019 American Transplant Congress
TCR Transgenes to Understand Human Xenotolerance Induction
Columbia Center for Translational Immunology, New York, NY
*Purpose: Swine thymus transplantation is a promising approach to clinical tolerance for pig-to-human xenotransplantation. In humanized mice, a swine thymus graft supports de novo selection…2019 American Transplant Congress
Lymphotoxin Signaling Regulates T Cell Lymphatic Trafficking
*Purpose: Lymphotoxin (LT) α1β2 is crucial for lymphatic organ development and orchestration of immune responses. LTα1β2 is preferentially expressed by regulatory T cells (Treg) for…2018 American Transplant Congress
Altered Function of Cytomegalovirus Specific T Cells in Transplant Recipients
1Stanford U, Stanford, CA; 2U Pennsylvania, Philadelphia, PA; 3VA Palo Alto, Palo Alto, CA.
Background: Cytomegalovirus (CMV) reactivation is associated with increased morbidity and mortality in transplant recipients. CMV establishes latency for the host's lifetime and frequently reactivates. Immunosuppression,…2018 American Transplant Congress
Identifying Specificity Groups in the CMV IE-1 T Cell Receptor Repertoire
Cytomegalovirus (CMV) continues to be a major problem for organ transplant recipients. T cells specific to the CMV antigens immediate-early (IE-1) and pp65 CMV govern…2018 American Transplant Congress
TLR2 with TCR Signaling Mobilizes Treg Lymphatic Migration
Background: Regulatory T cells (Treg) express high levels of lymphotoxin (LT) and bind the LT receptor (LTβR) on lymphatic endothelial cells (LEC). This receptor-ligand interaction…2017 American Transplant Congress
Expression of T-Cell Mediated Rejection (TCMR) Associated Genes in Native and Renal Allograft Renal Biopsies with Inflamed Scars (i-IFTA).
The presence of i-IFTA in allograft kidney biopsies is a bad prognostic parameter. However, despite the presence of T-cell infiltrates in these lesions there is…2017 American Transplant Congress
Contribution of γδ T-Cell Subsets and IL-17A Release to Ischemia Reperfusion Injury (IRI) and Kidney Allograft Rejection in Mice.
Ischemia reperfusion injury (IRI) contributes to acute allograft injury and to delayed graft function (DGF) which is a trigger for acute rejection after kidney transplantation…2017 American Transplant Congress
Evaluation of Function and TCR signaling Profile of CD57+ T Cells in Allo-Specific Immunity.
Our studies have showed that CD57+ cells are resistant to B7 costimulation blockade (CoB). We hypothesize that CD57+ cells are highly sensitive to T cell…
