TGF-b Plus Rapamycin Induce Foxp3 and Promote iTreg Development and Suppressive Function, Leading to Long-Term Allograft Survival
Path & Lab Med, CHOP & UPenn, Philadelphia, PA.
Given the major roadblocks to development of Treg-based cell therapy, pharmacologic approaches to expand endogenous Tregs warrant attention, including approaches with more sustained effects than…2018 American Transplant Congress
Sirolimus Use Improves Cancer-Free Survival Following Transplantation: A Single Center 10-Year Analysis
Introduction:In previous published results, we showed that the use of Sirolimus-based immunosuppression regimens had equivalent patient and graft 10-year survival compared to historical controls maintained…2018 American Transplant Congress
Belatacept-Refractory CD8+CD28–CD38hi Effector/Memory T Cells Are Targeted by mTOR Inhibition Leading to a Preferential Loss of CD40L
Calcineurin inhibitors (CNIs) and corticosteroids (CSS) have substantial untoward side effects, most notably nephrotoxicity. Consequently, the FDA approved belatacept for maintenance immunosuppression. We recently completed…2017 American Transplant Congress
IL-7 Receptor Heterogeneity as a Mechanism for Repertoire Change During Post-Depletional Homeostatic Proliferation and Its Relation to Costimulation Blockade Resistant Rejection.
Department of Surgery, Duke University School of Medicine, Durham, NC
Transplant patients treated with belatacept without depletional induction show high rates of costimulation blockade resistant rejection (CoBRR); this has been associated with CD57+ T cells.…2017 American Transplant Congress
The mTOR Signal Regulates Myeloid Derived Suppressor Cells Differentiation and Immunosuppressive Function in Acute Kidney Injury.
Urology, Zhongshan Hospital, Fudan University, Shanghai, China
The mammalian target of rapamycin (mTOR) is a serine–threonine kinase that senses various environmental stimuli. The mTOR signal controls innate and adaptive immune response in…2017 American Transplant Congress
Inhibition of Multiple Nodes in the PI3K/Akt/mTOR Pathway Synergistically Suppresses Epstein-Barr Virus B Cell Lymphomas.
Division of Abdominal Transplantation, Stanford School of Medicine, Palo Alto, CA
Treating post-transplant lymphoproliferative disorders (PTLD) remains a clinical challenge due to adverse effects such as graft rejection. mTOR inhibitors, including rapamycin (RAPA), have shown both…2017 American Transplant Congress
Timing of Mesenchymal Stem Cell Infusions Affects Rejection Free and Overall Islet Allograft Survival.
We recently demonstrated that autologous, bone marrow-derived mesenchymal stem cells (MSC) promote allogeneic islet engraftment and survival in a streptozotocin induced, cynomolgus monkey model of…2017 American Transplant Congress
CD4+IFN-γ+IL-10+ Regulatory Type 1 Cells Facilitate Prolongation of Graft Survival in Old Recipient Mice Treated with Rapamycin.
Although the elderly represent a rapidly growing population among transplant recipients, age-specific aspects have not been considered sufficiently in clinical trials. Moreover, age-specific effects of…2017 American Transplant Congress
Conversion from Calcineurin Inhibitor to Sirolimus in Kidney Transplantation Recipients with Malignancy.
Nephrology, Asan Medical Center, Seoul, Republic of Korea
Background: Kidney transplant recipients are at an increased risk of malignancy for various reasons, such as the chronic use of calcineurin inhibitor (CNI). Sirolimus (SRL),…2017 American Transplant Congress
Efficacy of Calcineurin Inhibitors Transferring to Rapamycin in Live Kidney Transplantation from Old Donors to Young Recipients.
Organ Transplant Center, The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China
Background Calcineurin inhibitor(CNI) nephrotoxicity is one of the major reasons for chronic allograft injury in live kidney transplantation from old donors to young recipients. Therefore…
