Novel Flow-Based Assay to Detect Allospecific T Cells in Transplantation Study
*Purpose: Identifying and phenotyping donor-reactive T cells in recipients following transplantation may further the understanding of interactions between the recipient’s immune system and donor antigen.…2020 American Transplant Congress
Neonatal Tolerance Induction: Behaviours of Allogeneic Spleen and Bone Marrow Inocula in Neonatal Mice are Largely Determined by the Nature of Their CD8 T Cells
University of Alberta, Edmonton, AB, Canada
*Purpose: Injected adult allo-spleen (SC) and bone marrow cells (BMC) traffic to secondary lymphoid organs, proliferate and spread throughout neonatal mice; allo-SC consistently cause acute…2020 American Transplant Congress
Non-Human Primate B Cells Into Regulatory B Cells by Activation with CpG
*Purpose: We previously generated Toll like receptor (TLR)-activated B cells in rodent settings. These B cells can suppress T cell proliferation via in vitro mixed…2020 American Transplant Congress
Evaluating Preformed Donor HLA Reactive T Cells Using PIRCHE-II Algorithm
*Purpose: De novo donor-specific HLA antibodies (dnDSA) production involves the indirect allorecognition pathway in which recipient CD4+T cells recognize donor-HLA-derived peptide and recipient HLA class…2019 American Transplant Congress
Anti-cmv Antibody (cmv-ab) And Cmv-specific Cytotoxic T Cell (cmv-tc) Positivity Are Essential To Control Severe Viremia In Seronegative (sero[-]) Pediatric Kidney Transplant Recipients (ped Ktx Pts).
Cedars-Sinai Medical Center, Los Angeles, CA
*Purpose: CMV infection represents a significant morbidity factor in KTx Pts, especially CMV sero(-) Ped Pts as infections tend to be more severe and recurrent.…2019 American Transplant Congress
Evaluating Allo-Specific CD57+ T Cells during Memory and Proliferative Responses
Department of Surgery, Duke University, Durham, NC
*Purpose: We have previously identified subsets of CD57+ T cells that are resistant to B7 costimulation blockade (CoB) in kidney transplant recipients. The objective of…2019 American Transplant Congress
High-Throughput Immune Synapse Detection as a Tool for the Measurement of T Cell Alloreactivity
*Purpose: Measurement of T cell alloreactivity may facilitate a more accurate prediction of graft outcome and the selection of patients for immunosuppression optimization. However, current…2019 American Transplant Congress
Microparticle Delivery to Lymph Nodes Induces Specific Suppression to Prolong Islet Survival
1Surgery, U. Maryland, Baltimore, MD, 2U.Maryland, Baltimore, MD, 3U. Maryland, College Park, MD
*Purpose: Microparticles (MP) loaded with peptide antigen plus other immune signals and delivered directly into lymph nodes (LN) can result in either proinflammatory or antiinflammatory…2019 American Transplant Congress
Using a Commercially Available Assay That Measures Cytomegalovirus-Specific CD4+ and CD8+ T-cell Immunity to Predict Clinically Significant Cytomegalovirus Events in Solid Organ Transplant Recipients
*Purpose: To assess the diagnostic performance and clinical utility of the Viracor CMV T-cell Immunity Panel (CMV-TCIP), which measures both CMV-specific Cd4+ and Cd8+ T-cell…2019 American Transplant Congress
Predicted Indirectly Recognizable H L A Epitopes Are Associated with T-cell Mediated Rejection among Kidney Transplant Recipients with Preformed and De Novo Donor-Reactive T-cells
*Purpose: Very recently Predicted Indirectly ReCognizable HLA Epitopes (PIRCHE) have been suggested to demonstrate early and late effects on kidney allograft outcomes. The association between…
