Tolerance Induction by Myeloid Progenitor Cells Modulates T and B Cell Responses
Allergy, Asthma and Immunology, Children's Mercy Hospital, Kansas City, MO
*Purpose: Modulation of the immune system using cellular therapy is an increasingly attractive option to prevent solid organ graft rejection, while at the same time…2019 American Transplant Congress
Engineering Regulatory T Cells With TCR-Signaling-Responsive Interleukin 2 Nanoparticles Provides In Situ Suppression Of Alloimmunity
*Purpose: Adoptive cell transfer of regulatory T cells (TReg) has shown great potential in animal models of auto- and alloimmunity. The translation of TReg therapies…2019 American Transplant Congress
Effect of Chronic Kidney Disease on Allo-Immune Response in Mice
*Purpose: Accumulation of memory T cells bearing markers of sustained antigen stimulation have been described in patients with chronic kidney disease (CKD). However, mouse models…2019 American Transplant Congress
Increasing Expression of B-cell Maturation Antigen during the Development of Recall Antibody Responses: A Prospective Pharmaceutical Target for B-cell Suppression?
Cedars-Sinai Med Ctr, Los Angeles, CA
*Purpose: Our previous study found that B cell maturation antigen (BCMA) is increasingly expressed by B/plasma cells during the development of de novo alloantibody responses.…2018 American Transplant Congress
Donor Bone Marrow CXCR4+ Foxp3+ Treg Cells Are Essential for Costimulation Blockade-Induced Long-Term Survival of Murine Limb Transplants
1CHOP, Philadelphia; 2UPenn, Philadelphia.
Vascularized composite allotransplantation (VCA) would likely be more widely performed if maintenance immunosuppression was not essential for graft acceptance. Accordingly, we used murine models of…2018 American Transplant Congress
Achieving Allograft Tolerance through Antigen-Specific Regulatory B Cells
IntroductionA complete understanding of the role of antigen-specificity in the development of B cell mediated allograft tolerance has remained elusive. Previous work in our lab…2018 American Transplant Congress
LAG-3 Deletion Upregulates Memory in a Dendritic Cell-Dependent Process
Introduction. Cardiac transplantation is critical for management of severe heart failure, but cardiac allografts frequently undergo chronic T-cell-mediated allograft rejection. Our research demonstrates that Lymphocyte…2018 American Transplant Congress
Glycolytic Bias in mTORC2-Deficient Dendritic Cells Potentiates Antigen-Specific Immunity and Accelerates Graft Rejection
The mechanistic target of rapamycin (mTOR) is known to function in two complexes: mTOR complex 1 (mTORC1) and mTORC2. While the function of mTORC1 in…2018 American Transplant Congress
Origin and Traffic of Donor-Derived Extracellular Vesicles during Allo-Sensitization
The idea that donor dendritic cells (DCs) transplanted with the grafts and mobilized to draining lymphoid tissues (dLTs) present donor MHC molecules to allo-reactive naïve…2017 American Transplant Congress
Delayed Tolerance Induction Protocol for Vascularized Composite Allografts in Non-Human Primates: The Immunomodulatory Effect of Donor Bone Marrow Transplantation Does Not Prevent the Development of Chronic Rejection in the Absence of Durable Mixed Chimerism.
Massachusetts General Hospital, Boston, MA
PURPOSE: Donor bone marrow transplantation (DBMT) has been investigated in experimental and clinical vascularized composite allotransplantation (VCA). With longer-term follow-up, reports of chronic VCA rejection…
