Targeting Cell Metabolism for Efficient Large-Scale Expansion of Functional Regulatory T Cells
University of Kentucky, Lexington, KY
*Purpose: A growing body of evidence recognizes the balance between graft-reactive effector T cells and graft-protective regulatory T cells (Tregs) as the ultimate determinant of…2019 American Transplant Congress
Regulating T Cell Responses by Forced Transgenic Expression of Decay-Accelerating Factor
1Icahn School of Medicine at Mount Sinai, New York, NY, 2Cleveland Clinic, Cleveland, OH
*Purpose: Decay-accelerating factor (DAF, CD55) is a cell surface expressed, glycophosphatidylinositol-(GPI)-anchored, complement regulator. Previous studies showed that during cognate T cell/antigen presenting cell (APC) interactions…2019 American Transplant Congress
Lymphotoxin Signaling Regulates T Cell Lymphatic Trafficking
*Purpose: Lymphotoxin (LT) α1β2 is crucial for lymphatic organ development and orchestration of immune responses. LTα1β2 is preferentially expressed by regulatory T cells (Treg) for…2019 American Transplant Congress
mTOR Inhibitors Enhance Antitumor Activity of Liver Resident NK Cells
Gastroenterology and transplant Surgery, Hiroshima University, Hiroshima, Japan
*Purpose: The immunosuppressive regimen currently used after organ transplantation reduces adaptive components. Therefore, the innate immune cells play pivotal roles in immune surveillance and defense…2019 American Transplant Congress
Severe Acute Rejection In Human Leukocyte Antigen Identical Renal Transplants: Reviving Mixed Lymphocyte Culture
*Purpose: Human leukocyte antigen-identical renal transplants among siblings account for a minority of all renal transplants, but have excellent long-term outcomes due to very minimal…2019 American Transplant Congress
Cellular And Molecular Characteristics Of Intra-graft Lymphoid Aggregates In Chronic Lung Allograft Dysfunction
*Purpose: Lymphoid aggregates (LAs) have been identified within lung allografts post lung transplant (LTx). However, it remains controversial whether they represent benign lymphoid tissue or…2019 American Transplant Congress
Redox State of HMGB1 Drives Ischemia-Reperfusion Injury in Human Liver Transplantation
1Pathology & Laboratory Medicine, UCLA, Los Angeles, CA, 2Surgery, UCLA, Los Angeles, CA
*Purpose: Ischemia-reperfusion injury (IRI) is a major risk factor of acute and chronic graft rejection in orthotopic liver transplantation (OLT) involving a complex interplay between…2018 American Transplant Congress
Biomaterial-Based Localized and Controlled Delivery of Tofacitinib to Actuate Enhanced Costimulation Blockade and Promote Long-Term Transplant Survival
Complications from long-term use of calcineurin inhibitors remain a major issue for transplant patients and alternative therapies are highly needed. We investigated two innovative drug…2018 American Transplant Congress
Prolongation of Skin Allograft Survival through Dietary Supplementation of Ayrl Hydrocarbon Receptor Ligands
Transplant Surgery, University of Wisconsin, Madison, WI.
The Aryl Hydrocarbon Receptor (AHR) is a cytosolic transcription factor with numerous endogenous and xenobiotic ligands playing a key role in a number of cellular…2018 American Transplant Congress
TLR-Activated Bregs Promote Islet Allograft Tolerance in an IL-10-Independent and TGF-β-Dependent Manner
Center for Transplantation Sciences, Massachusetts General Hospital, Boston, MA.
Background: We previously demonstrated the potent capacity of regulatory B cells (Bregs) to mitigate allograft immunity. Recently, we produced TLR-activated B cells in vitro that…
