Acute Rejection in Non-Human Primates Treated with Belatacept Is Mediated by a Unique CD8 Memory Subset.
Belatacept is a high affinity version of the fusion protein CTLA4-Ig that blocks CD28 mediated T cell costimulation, providing a more targeted/less toxic form of…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.…2015 American Transplant Congress
VLA-4 Blockade Inhibits Endogenous Memory CD8 T Cell-Mediated Rejection of Cardiac Allografts
Endogenous memory CD8 T cells infiltrate cardiac allografts within 24 hours of reperfusion and are activated to proliferate and produce IFN-γ in response to donor…2015 American Transplant Congress
Allograft Class II MHC and CD40 Expression Are Required for Endogenous Memory CD8 T Cell Proliferation in Cardiac Allografts Subjected to Prolonged Cold Ischemic Storage
Endogenous memory CD8 T cells infiltrate MHC-mismatched cardiac allografts and produce IFN-γ in response to donor class І MHC within 24 hrs after graft reperfusion…2015 American Transplant Congress
CD4 T Cell Mediated Help Is Required for Endogenous Memory CD8 T Cell Proliferation in Cardiac Allografts Subjected to Prolonged Cold Ischemic Storage
Endogenous memory CD8 T cells infiltrate MHC-mismatched cardiac allografts and produce IFN-γ in response to donor class І MHC within 24 hrs after graft reperfusion…2015 American Transplant Congress
Aquaporin 4 Blockade Is a Novel Strategy Targeting Ischemia/Reperfusion Injury in Heart Transplantation
1Immunology, Cleveland Clinic, Cleveland, OH; 2Aeromics, LLC, Cleveland, OH.
Aquaporin 4 (AQP4) belongs to the family of small integrin transmembrane proteins that are highly permeable to water. It was recently shown that human and…2015 American Transplant Congress
IL-21 Regulates Creation of Tertiary Lymphoid Organs in Chronic Allograft Rejection
BACKGROUND: IL-21 is a cytokine expressed almost exclusively by cells of the adaptive immune system. This makes it an attractive target for reducing chronic allograft…2015 American Transplant Congress
CD3+CD4+ROR gamma t+ TH17 Cells Do Not Play a Critical Role in Islet Allograft Rejection
Medicine, The Transplant Institute, Beth Israel Deaconess Medical Center, Boston, MA.
We have developed a “color-coded” adoptive transfer model for T cell subset identification that enables serial analysis of islet allograft infiltrating yellow induced regulatory T…2015 American Transplant Congress
Effector T Cell Migration to Pancreatic Islet Allografts Is Dependent On Donor Antigen Recognition and Not Gαi Chemokine Signaling
Thomas E. Starzl Transplantation Institute, UPMC, Pittsburgh, PA.
Infiltration of the graft with host effector T cells after transplantation is a key step in the pathogenesis of both acute and chronic rejection. Recent…2015 American Transplant Congress
Immunological Aspects of Iron Overload in Heart and Kidney Transplantation
Background: Clinical data suggest that iron (Fe) overload deleteriously affects graft survival after heart (HTX) and kidney transplantation (KTX) but possible immunologic mechanisms underlying this…
