Functional Mystacial Pad Allograft Tolerance Induced and Maintained by Vascularized Bone Marrow Transplant.
Background: Accumulating findings indicate that vascularized bone marrow (VBM) transplantation plays a critical role to promote tolerance of vascularized composite allografts (VCA) without life-long immunosuppression.…2017 American Transplant Congress
Generation of Potent Monocytic Myeloid-Derived Suppressor Cells from Rhesus Macaque Bone Marrow.
Surgery (Transplant), University of Pittsburgh, Pittsburgh, PA
Background: Myeloid-derived suppressor cells (MDSC) have shown promise in inhibiting allograft rejection and in promoting transplant tolerance in rodent models. We recently reported that monocytic…2017 American Transplant Congress
Biological Interplay Between Circulating HLA-sp Alloreactive Memory B-Cells and Long-Lived Plasma Cells in Kidney Transplant Patients Undergoing Chronic ABMR.
Alloreactive humoral responses are one of the main causes of immune-mediated allograft injury in kidney transplantation. Different biological compartments are involved in the generation and…2017 American Transplant Congress
In Vivo Administration of Plerixafor in Humans Mobilizes Bone Marrow Resident Plasma Cells That Demonstrate Apoptosis in Both Bone Marrow and Peripheral Blood.
1University of Cincinnati, Cincinnati; 2Cincinnati Children's, Cincinnati; 3Duke, Durham
Plasma-cell (PC) targeted therapies can reduce HLA sensitization. However, bone marrow (BM) niche resident plasma cells (BMNRPC) demonstrate resistance to proteasome inhibitor (PI) therapy. Plerixafor…2017 American Transplant Congress
Vascularized Bone Marrow Mechanisms of Immunomodulation.
University of Maryland School of Medicine, Baltimore, MD
Introduction:Hand and face transplants containing co-transplanted bone may have improved outcomes. We have previously utilized a NHP model to demonstrate that VCA containing VBM have…2017 American Transplant Congress
Transient High Dose Tacrolimus Allows Tolerance of a Vascularized Composite Allograft Tolerance Across a Full MHC Mismatch.
Plastic and Reconstructive Surgery, Johns Hopkins University, Baltimore, MD
Purpose: The achievement of tolerance in Vascularized composite allografts (VCA) could avoid the risks of immunosuppression in this setting. We investigated strategies for tolerance induction…2017 American Transplant Congress
Tolerogenic Potential, Migratory Pathways, Engraftment and Long-Term Survival of Human Hematopoietic Chimeric Cells – A Novel Strategy to Induce Tolerance in Transplantation.
Department of Orthopaedics, University of Illinois at Chicago, Chicago, IL
Background: Cell-based therapies represent a new promising strategy for tolerance induction in transplantation. One of the methods for immune response modulation in solid organ and…2017 American Transplant Congress
Induction of Tolerance to Renal Allografts in Non Human Primates by Concomitant Donor-Matched Vascularized Osteomyocutaneous Allotransplantation.
Introduction: We hypothesized that hematopoietic stem cell (HSC) niches in bone marrow of vascularized osteomyocutaneous allografts (VOMA) will facilitate mixed chimerism (MC) and tolerance to…2016 American Transplant Congress
Impact of CXCR4/CXCL12 Blockade on Normal Plasma Cells In Vivo.
Department of Surgery, Division of Transplant Surgery, Mayo Clinic, Rochester, MN.
Introduction:Plasma cells (PCs) are a major source of alloantibody in transplant patients.They are resistant to current therapy. Since receptor/ligand interactions in the stromal environment are…2016 American Transplant Congress
iNKT Cell Ligands Administered with Bone Marrow Cells Expand Allo-Specific Regulatory T Cells In Vivo and Establish Transplant Tolerance.
Invariant natural killer T(iNKT) cells have the powerful potential to expand regulatory T cells(Tregs), especially when they are presented α-galactosylceramide(aGC) by B cells. We previously…
