Potential Mechanism Involving Regulatory T Cells in Induction of Tolerance in Mouse Vascularized Composite Allotransplantation Under Combined Costimulation Blockade.
Background: Role of Regulatory T cells in vascularized composite allotransplantation (VCA) remains to be elucidated. In this study, we investigate potential mechanism involved in Tregs…2017 American Transplant Congress
Rapamycin Directly Alters Human Endothelial Cell Alloimmunogenicity.
The mTOR inhibitor rapamycin (Rapa) is known to suppress T cell function. However, many of its in vivo effects, particularly its synergistic effects with costimulation…2017 American Transplant Congress
Applicability and Safety of a Regulatory T Cell Therapy in Adult Liver Transplantation: The “ThRIL” Phase I First-in-Human Trial.
MRC Centre for Transplantation, King's College London, London, United Kingdom
Aim“ThRIL” is a multiple site, open-label, uncontrolled, phase I clinical trial assessing the safety and applicability of a CD4+CD25+FOXP3+ regulatory T cell (Treg) immunotherapy in…2016 American Transplant Congress
The mTORC2 Activation Is Critical for Hepato-Cytoprotection Against Ischemia and Reperfusion Injury.
Background & AimsRapamycin and Everolimus have been used in liver transplant patients, particularly those with calcineurin inhibitor-related nephrotoxicity and hepatocellular carcinoma. Although designed as mTORC1…2016 American Transplant Congress
Peritransplant Costimulation Blockade Combined with a Short-Course of Rapamycin Prevents Rejection of Vascularized Composite Allografts.
[Background] Reconstructive transplantation represents a valid therapeutic option after devastating tissue loss. Routine clinical application, however, is hampered by the toxicity of long-term maintenance immunosuppression.…2016 American Transplant Congress
Heterologous Persistent and Latent Viral Infections Do Not Impact Graft Survival.
1Duke University, Durham; 2Emory University, Atlanta.
Purpose: Infection induces costimulation-resistant memory T cells with heterologous alloreactivity. Rapamycin has been shown to mitigate the effect of these cells in transplant rejection. Previous…2016 American Transplant Congress
The Impact of a Novel Dual Adenosine Triphosphate-Competitive mTOR Inhibitor (TORKinib) on Alloimmunity and Transplant Survival.
Background: Rapamycin (RAPA), an immunosuppressive agent, inhibits the mechanistic target of Rapamycin (mTOR), the kinase subunit of two mTOR- containing complexes (mTORC1 and mTORC2). While…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
Only 13% of Liver Transplant (LT) Recipients with Moderate to Severe Kidney Disease (KD) Tolerate Conversion to Everolimus and Reduced Tacrolimus (EVR/rTac).
Liver Transplant, Cedars-Sinai Medical Center, Los Angeles, CA.
EVR/rTac has been reported to improve renal function in LT recipients with adequate kidney function (eGFR > 80ml/min); however, this strategy in LT patients with…2016 American Transplant Congress
Monocyte Recruitment to HLA Class I Antibody-Activated Endothelial Cells Is Dependent Upon mTOR.
Pathology & Laboratory Medicine, UCLA, Los Angeles, CA.
Aim: Antibody-mediated rejection (AMR) is a major issue affecting solid organ transplants, manifesting with recruitment of monocytes to the endothelium of the allograft. The purpose…
