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…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…2017 American Transplant Congress
BKV Clearance Time Correlates with T-Cell Receptor Repertoire Shape and Exhaustion State of BKV-Specific T-Cells in Renal Transplant Patients with Severe BKV Infection.
Reactivation of the BK polyomavirus is known to lead to severe complications in kidney transplant patients. The current treatment strategy relies on decreasing the immunosuppression…2017 American Transplant Congress
Contribution of Donor versus Recipient T Cells in Face Transplant Rejection.
1Brigham and Women's Hospital, Boston; 2Broad Institute of MIT and Harvard, Cambridge
BackgroundSkin-containing transplants such as facial allografts contain resident populations of donor T cells. Although the role of T cells in acute rejection is well established,…2017 American Transplant Congress
In Depth Characterization of Ex Vivo Expanded Polyclonal Regulatory T Cells Used in a Phase I Clinical Trial Following Kidney Transplantation.
Initial clinical trials have investigated the safety of regulatory T cells (Tregs) as a therapy during aberrant immune activation, like graft-versus-host disease (GVHD) following stem…
