Lymph Node Stromal Laminins Differentially Regulate T Cell Immunity and Tolerance.
University of Maryland, Baltimore, MD.
Background:Our recent work demonstrated that laminins α4β1γ1 and α5β1γ1, components of the lymph node (LN) stroma, are differentially regulated. Tolerance is associated with relatively higher…2016 American Transplant Congress
Rapamycin Prolongs Cardiac Allograft Survival in a Mouse Model by Inducing Myeloid-Derived Suppressor Cells.
Mammalian target of rapamycin (mTOR) inhibitors are the main immunosuppressive drugs for organ transplant recipients. Nevertheless, the mechanisms by which mTOR inhibitors induce immunosuppression is…2016 American Transplant Congress
Acquired Down-Regulation of B Cell Function Induced by Donor Blood Group Antigens After ABO-Incompatible Kidney Transplantation.
Background: The long-term of B cell immunobiology against donor blood group antigen has not been elucidated in ABO incompatible kidney transplantation (ABOi KTx).Methods: The antibody…2016 American Transplant Congress
Erythropoietin (EPO) Mediates Spontaneous Kidney Transplant Tolerance in Mice.
Spontaneous allogeneic kidney transplant tolerance occurs in mice, but the underlying mechanisms are unknown. Building upon recent human data showing that EPO, an erythropoietic hormone…2016 American Transplant Congress
Rapamycin Nanotherapy Delays Heart Transplant Rejection.
Background:In patients, allograft survival requires a cocktail of immunosuppressive drugs, while experimentally antibodies targeting the innate immune system have been shown to induce long-term tolerance,…2016 American Transplant Congress
PD-L1/PD-L2-Expressing B-1a Cells Inhibit Allo-Reactive T Cells in Mice.
Donor lymphocyte infusion (DLI) induces donor-specific hypo responsiveness or immune-tolerance among allo-reactive T cells in different organ transplantation models. However, the optimal cell source or…2016 American Transplant Congress
iNKT Cell Activation Under Co-Stimulatory Blockade Establishes Mixed Chimerism Through Thymic Regulatory T Cell Activation.
Background: Invariant natural killer T (iNKT) cells have recently garnered considerable attention for their potential to induce regulatory T cells (Tregs). We previously reported a…2016 American Transplant Congress
Three-Year Outcome After HSCT with Subsequent KT from the Same Haploidentical Donor without Immunosuppression.
Allogeneic hematopoietic stem cell transplantation (HSCT) can lead to donor-specific tolerance. Patients reported in the literature that underwent kidney transplantation (KT) after a previous HSCT…2016 American Transplant Congress
Designing a Novel Highly Selective Immunoproteasome Inhibitor That Promotes Longterm Heart Allograft Acceptance While Inducing Immune Cell Exhaustion, Treg Induction and Memory Cell Suppression.
The constitutive Proteasomes (c-20S) are ubiquitously expressed cellular proteases that degrade polyubiquitinated proteins and regulate cell functions. However, immunoproteasomes (IP or i-20S) are primarily expressed…2016 American Transplant Congress
Mechanistic Insights into How Targeting of HDAC10 Promotes Foxp3+ Treg Cell Suppressive Activity, Gene Expression and Metabolism, and Enhances Allograft Survival.
1Children's Hospital of Philadelphia, Philadelphia; 2University of Pennsylvania, Philadelphia.
Foxp3+ T-regulatory (Treg) cells are key regulators of immune responses that can result in unwarranted inflammation and promote allograft rejection. From a theoretical perspective, targeting…
