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
Th17 Mediates Inflammatory Responses After Lung Transplantation
Background: Long-term outcomes after lung transplantation are markedly worse than for other organs. The mechanisms that determine lung transplant rejection are not clear. The role…2015 American Transplant Congress
Cytotoxic CD8 T Cell Recognition of Acquired, Intact MHC Alloantigen On Host Dendritic Cells Promotes Acute Allograft Rejection
University of Cambridge, Cambridge, United Kingdom.
IntroductionAlthough there is increasing evidence that recipient DCs can acquire intact MHC class I by trogocytosis from parenchymal cells, the functional relevance of the 'semi-direct'…2015 American Transplant Congress
Rejection of an Allograft Through Non-MHC Antigens Does Not Translate to the Rejection of a Different Allograft from the Same Donor in Mixed Chimeras
We previously showed that tolerance, induced by mixed chimerism in mice, is antigen-specific: tolerance of heart and skin allografts is dependent on Foxp3+ cells that…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
CHBP Suppresses Acute Rejection by Inhibition Maturation of Dendritic Cells though Jak-2/STAT3/SOCS1 Signal in Rat Kidney Transplantation
Background. Renal acute rejection (AR) affects both allografts and recipients survival. We recently synthesized a novel proteolysis-resistant cyclic helix B peptide (CHBP), which exerts promising…2015 American Transplant Congress
Plasma Levels of Donor-Derived Cell-Free DNA Increase With Rejection and Often Decrease After Treatment in Organ Transplant Recipients
1CareDx, Inc, Brisbane, CA; 2Cedars-Sinai Medical Center, Los Angeles, CA.
Purpose: Donor-derived cell-free DNA (dd-cfDNA) is a potential biomarker of acute cellular rejection (ACR) in organ transplant recipients. dd-cfDNA levels in longitudinal plasma samples from…2015 American Transplant Congress
Induction With ATG Is Not Associated With Increased Infections After Kidney Transplant Among HIV Positive Patients: Results of a National Study
1JHU, Baltimore; 2UAB, Birmingham.
Anti-thymocyte globulin (ATG) is widely used for induction, particularly for those at high risk for rejection. HIV+ kidney transplant (KT) recipients have 3 fold higher…2015 American Transplant Congress
Hepatocyte-Related miR-193a-3p Is Over-Expressed in Allograft Biopsy from Liver Tolerant Recipients
While liver transplantation is the treatment of choice for end-stage liver diseases, its success is compromised by the need to administer life-long immunosuppression, which negatively…2015 American Transplant Congress
Deceased Donor and Class II Donor Specific Antibody Predict Interface Activity While Increased Age at Time of Biopsy Predicts Fibrosis in Long-Term Pediatric Liver Allografts With Normal Liver Tests: iWITH Clinical Trial
Background: Although multiple single centers have reported deterioration of pediatric liver grafts in the face of normal liver tests, neither risk nor mechanism is understood.Methods:…
