In Vitro Evidence That CTLA4Ig Attenuates Recall Alloantibody Responses
Background: CTLA4Ig is an agonist that blocks CD28-B7 costimulation, downregulating T cell immunity, but also appears to negate T cell-dependent B cell activation, thus inhibiting…2015 American Transplant Congress
NK-Cell Subset Distribution, Renal Function and Biopsy Findings in Kidney Transplant Recipients With HLA Donor-Specific Antibodies
Background: Detection of post-transplant donor-specific anti-HLA antibodies(DSA) constitutes a risk factor for kidney transplant (KT) loss. NK-cell antibody-dependent cell mediated cytotoxicity(ADCC) has been proposed to…2015 American Transplant Congress
Endosome-Based Activation of Non-Canonical NF-kB Signaling By Membrane Attack Complexes
Using sera from transplant patients with high-titer panel reactive antibody (PRA), we previously described a model for studying the effects of alloantibody binding and complement…2015 American Transplant Congress
CN Inhibition (But Not mTOR Inhibition) of a Novel CD8+ T Cell Regulatory Mechanism Results in Higher Alloantibody Posttransplant
Department of Surgery, CTC, The Ohio State University Wexner Medical Center, Columbus, OH.
MTOR inhibitors [mTORi; Rapamycin, (Rapa)] and calcineurin inhibitors [CNi; Tacrolimus (Tac)] are immunosuppressive drugs commonly used to suppress the rejection of transplanted organs and tissues.…2015 American Transplant Congress
Immunological Characterization of Full Facial Transplant Recipients
Background: Despite the skin being considered the most immunogenic of all human tissues, full facial transplantation (FFT) has become a life transforming procedure with encouraging…2015 American Transplant Congress
Does the C1q Assay Predict the Result of Lymphocyte Flow Cross-Match (FCxM) in Potential Renal Transplant Recipients With HLA-DSA and AHG-CDC CxM negative?
Background. The presence of pre-transplant HLA donor specific antibodies (DSA) is a recognized risk factor for acute rejection. However, due to the test's (LUMINEX) high…2015 American Transplant Congress
Characterization of a Nude Mouse Model of Allosensitization Conditioned by Adoptive Transfer of Follicular T Helper Cells
Comprehensive Transplant Center, Cedars-Sinai Medical Center, Los Angeles, CA.
Background Follicular T helper (Tfh) cells play a critical role in follicular B cell activation and maturation during antibody responses to allograft. Here we report…2015 American Transplant Congress
Marked Suppression of Posttransplant Alloantibody Production and Primed B cell Function In Vivo by mTOR Inhibition Compared to Calcineurin Inhibition
Department of Surgery, CTC, The Ohio State University, Columbus, OH.
mTOR inhibitors [mTORi; Rapamycin, (Rapa)] and calcineurin inhibitors [CNi; Tacrolimus (Tac)] are immunosuppressives commonly used to suppress rejection of transplants. Despite widespread use following transplantation…2015 American Transplant Congress
Combination of Non-HLA and HLA-DSA Antibodies Identifies Liver Transplants Recipients With Highest Risk for Fibrosis Progression and Mortality
Recent data has shown an increased risk of fibrosis progression in HCV viremic liver transplant (LT) recipients with HLA DSA in serum. However, the role…2015 American Transplant Congress
Preformed Anti-HLA DP Donor Specific Antibodies Are Clinically Significant in Renal Transplantation
Renal and Transplant Medicine, Imperial Healthcare NHS Trust, London, United Kingdom.
Background: Whilst preformed [PF] anti-HLA A, B, DR and DQ donor specific antibodies [DSAbs] are associated with poorer allograft outcomes secondary to antibody mediated injury,…
