CD14+ Monocytes Play a Critical Role in Initiating Xeno-Recognition, Costimulation and Immune-Responses to Porcine Endothelial Cells
Duke University School of Medicine, Durham, NC
*Purpose: Porcine endothelial cells (PECs) are the first barrier between a pig’s organ and circulating immune system. Unlike allogeneic immune responses, PECs fail to induce…2022 American Transplant Congress
Validation of Shared T Cell Epitope Analysis as a Tool to Detect Preformed Donor-Reactive CD4+ Memory T-helper Cells
*Purpose: Adaptive immunity creates immunological memory after the first response to a specific foreign antigen including HLA. During this response, adaptive immunity memorizes the molecular…2020 American Transplant Congress
Clinical Significance of T Cell and B Cell Epitope Prediction as a Risk Factor of De Novo DSA Production after Kidney Transplantation
*Purpose: Chronic antibody-mediated rejection caused by de novo DSA (dnDSA) is a major cause of graft failure. Risk prediction of dnDSA would be important for…2020 American Transplant Congress
Gal9/Tim-3 Pathway was Required for Endometrial Stem Cells to Induce Peripheral Tolerance of Cardiac Allograft
*Purpose: The existing immunosuppressants seem to have little effect on Cardiac Allograft Vasculopathy but with obvious side effects. ERCs (Endometrial stem Cells), which are mesenchymal-like…2019 American Transplant Congress
Tacrolimus Activated BMP Signaling Acts in Synergy with Stress-Activated FOXO1 to Induce Loss of Beta-Cell Function and Identity
*Purpose: Tacrolimus, the most widely used immunosuppressive drug, is known to be highly diabetogenic. It is thought to trigger β-cell death through inhibition of the…2018 American Transplant Congress
Allogeneic T Follicular and T Conventional Responses Assessed by Proliferation, Cytokine Production, and TCR Clonality
1Thomas E. Starzl Transplantation Institute, Pittsburgh; 2Adaptive Biotechnologies, Seattle.
Background: Human CD4+ T cell allo-immunity plays pivotal roles during cellular and humoral allograft rejection. Our previous analysis showed that allo-reactive precursors were present in…2016 American Transplant Congress
Indirect Allo-Antigen Stimulation Identifies the Presence of Either Regulatory IL-10 or of Effector Cytokines IFN-g, IL-21, IL-17a Production by Human Blood Allo-Reactive Memory TFH and TCONV CD4+ T Cells.
Surgery, Thomas E. Starzl Transplantation Institute, Pittsburgh, PA.
Background: It is well accepted that human CD4+ T cell allo-immunity plays pivotal roles during cellular and humoral allograft rejection. While our previous analysis showed…2015 American Transplant Congress
Dramatic Primary Expansion of Indirect CD4 T Cells to Allogeneic APCs In Vivo
An ongoing question regarding the primary allograft response is the relative contribution of the 'direct' (donor MHC-restricted) versus 'indirect' (host MHC-restricted) pathways of T cell…2015 American Transplant Congress
Effective Control of Anti-Xenogeneic IL-17 Response for Tolerance Induction in Xenogeneic Islet Cell Transplantation
We have previously shown that peri-transplant infusion of donor cells treated with 1-ethyl-3-(3'-dimethylaminopropyl)-carbodiimide (ECDI) in combination with peri-transplant anti-CD20 and rapamycin induce permanent porcine islet…2015 American Transplant Congress
IgM+ Antigen Binding B Cells in Peripheral Blood Regulate IFNγ Production in Response to HLA Proteins
Chronic antibody mediated rejection (CAMR) is a major cause of graft loss in renal transplant recipients. Previous work utilising an IFNγ ELISPOT assay revealed two…
