Noninvasive Imaging of CD122+ T Cells via Immuno-PET for Detection of Acute Cellular Rejection
*Purpose: Acute cellular rejection (ACR) remains a clinically important problem following organ transplantation. Clinically, suspicion of ACR is dependent upon serum laboratory values, and diagnosis…2020 American Transplant Congress
Recipient Expression of C-Type Lectin Receptor Mincle Promotes Rapid T Cell Homeostatic Recovery Following Antibody Mediated Lymphoablation
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: Antibody-mediated lymphocyte depletion is widely used in transplantation. We recently established that T cell recovery in mouse heart allograft recipients treated with anti-thymocyte globulin…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
Utility of dd-cfDNA in TCMR 1A and Borderline Allograft Rejection
*Purpose: The value of donor-derived cell-free DNA (dd-cfDNA, AlloSure) as a molecular marker for the early diagnosis of mild T-cell mediated rejection (Banff TCMR 1A…2020 American Transplant Congress
DEPTOR Expression within CD4+Foxp3+ T Regulatory Cells is Crucial for B Cell Activation Responses and Immunoregulation
1Boston Children's Hospital, Boston, MA, 2Lavel University, Quebec, QC, Canada
*Purpose: We have previously reported that the intracellular protein DEPTOR stabilizes Foxp3 expression, enhances suppressive Treg function and inhibits Treg dedifferentiation. Overexpression of DEPTOR within…2020 American Transplant Congress
High Frequencies of Donor-Derived Memory T and NK Cells in the Blood of Lung Transplant Recipients May Contribute to Protection from Chronic Lung Allograft Dysfunction
*Purpose: After lung transplantation (LuTx), a transient chimerism of donor cells exists in the blood of recipients due to the migration of lymphocytes from the…2020 American Transplant Congress
T Follicular Regulatory Cell Deficiency Enhances Secondary T Follicular Helper Cell Responses after Transplantation
*Purpose: Deleterious alloantibodies result from T follicular helper (Tfh) cell-driven germinal center (GC) reactivity. T follicular regulatory (Tfr) cells are a subset of regulatory T…2020 American Transplant Congress
Influence of Microbial Communities on Transplantation
*Purpose: A diverse microbiome is important in the generation, maintenance, and function of the immune system. Specific bacterial communities may have a relationship with organ…2020 American Transplant Congress
Challenges in Manufacturing Clinically Competent Regulatory T Cells from Obese Renal Transplant Recipients
Surgery, University of Kentucky, Lexington, KY
*Purpose: The obesity epidemic has expanded rapidly over the last decade. Our program is developing a novel clinical protocol using expanded autologous regulatory T cell…2020 American Transplant Congress
IL-10 Signaling in T Cells is Essential for Induction of Transplant Tolerance
Plastic Surgery, Johns Hopkins University, Baltimore, MD
*Purpose: Induction of long term transplant survival by “costimulation blockade” (CoB) is achieved through deletion of abortively activated alloreactive T cells and generation of graft…
