Immunologically Tolerant Liver Transplant Recipients Are Characterized by Donor-Specific Hypo Responsiveness of Circulating T-cells
*Purpose: Lifelong treatment with immunosuppressive drugs (IS) to prevent graft rejection in transplant recipients is accompanied by side effects. Some recipients are considered to be…2019 American Transplant Congress
Deficiency of the Transcription Factor Satb1 in T Cells Promotes Solid Organ Allograft Survival
*Purpose: Conventional CD4+ T cells are key effectors of allograft rejection and novel therapies limiting their response may hold promise in the context of organ…2019 American Transplant Congress
Prevention of Diabetes in the NOD Mice Reconstituted with Bone Marrow Cells from Allogeneic CD4 Knockout, CD8 Knockout or B-Cell Knockout B6 Mice
University of Louisville, Louisville, KY
*Purpose: Type 1 diabetes (T1D) is an autoimmune disorder characterized by destruction of the pancreatic beta cells by both humoral- and cell-mediated immune mechanisms. Transplantation…2019 American Transplant Congress
Superiority of Donor-Specifically vs. Polyclonally Expanded Regulatory T Cells in Controlling Graft Rejection in the NSG Mouse Human Skin Graft Model
*Purpose: Naturally occurring CD4+CD25highFOXP3+ Regulatory T cells (Tregs) function as mediators of immune homeostasis. So, they are beginning to be utilized for controlling hyper-immunity and…2019 American Transplant Congress
Comparative Use of Single mTOR vs Dual mTOR/PI3K Inhibition in Regulatory T Cell Expansion for Clinical Application in Transplantation
University of Kentucky, Lexington, KY
*Purpose: Experimental and pre-clinical evidence suggest that adoptive transfer of regulatory T cells (Tregs) could be an appropriate therapeutic strategy to induce tolerance and improve…2019 American Transplant Congress
Dichotomous Role Of Donor T Cells In The Efficacy Of Tolerogenic Therapies For Transplant Rejection
Plastic Surgery, Johns Hopkins University, Baltimore, MD
*Purpose: Costimulation blockade-based regimens are a promising strategy to promote transplant tolerance. However, their efficacy is affected by multiple factors, many of which remain unknown.…2019 American Transplant Congress
Acquired Resistance to Transplantation Tolerance as a Result of Prior Pregnancy Requires B Cells
Departments of Surgery and Medicine, University of Chicago, Chicago, IL
*Purpose: Clinical data suggest allogeneic pregnancy is a sensitizing event; however, data from mouse models suggests it induces fetal-specific regulatory T cell (Treg) expansion and…2019 American Transplant Congress
Chimeric Allografts Induced by Stem Cell Mobilizing Agents in a Mouse Model of Kidney Transplantation: Role of CD133 Stem Cells
Johns Hopkins University School of Medicine, Baltimore, MD
*Purpose: It has been reported that a stem cell mobilizing therapy using a combination of AMD3100 and low dose FK506 (AF) enabled immunosuppressive-free long-term kidney…2019 American Transplant Congress
Allograft Survival is Influenced by Gut Microbiota-Dependent Modulation of Innate Immunity
*Purpose: The gut microbiota driven inflammatory response and the host immune system engage bidirectional regulation of each other. These interactions are poorly characterized in organ…2019 American Transplant Congress
Generation of Human/Pig Hybrid Thymus to Achieve Immune Tolerance to Pig Antigens with Optimal Immune Function
Columbia University, New York, NY
*Purpose: Thymus transplantation is a promising approach to induce T-cell tolerance for xenotransplantation. We have previously shown that humanized mice generated with human hematopoietic stem…
