Determining the Relative Immunogenicity of HLA Mismatches with Calcineurin Inhibitor Immunosuppression: An Analysis of the BENEFIT and BENEFIT-EXT Renal Transplant Cohort
We studied the relative immunogenicity of HLA-A, -B, -C, -DR and -DQ MM (serological) in a cohort of 291 kidney transplant patients from the BENEFIT…2018 American Transplant Congress
Circulating Exosomes with Lung Self-Antigens, Kα1Tubulin and Collagen V, and Immune Regulatory Proteins in Lung Transplant Recipient with Primary Graft Dysfunction
Norton Thoracic Institute, St. Joseph's Hospital & Medical Center, Phoenix.
Background: Circulating exosomes isolated from lung transplant recipients (LTxRs) with acute or chronic rejection contains lung self-antigens (SAgs), K alpha 1 tubulin (Kα1T) and collagen…2018 American Transplant Congress
Antibody-Verified Eplet Mismatches as Determinants of Premature Kidney Transplant Loss
Introduction: HLA matching at the epitope level offers new opportunities to identify compatible donors for transplant candidates. HLAMatchmaker deduces B-cell epitope ('eplets' in HLAMatchmaker) mismatches…2018 American Transplant Congress
Novel Function of TIE2 in Immunoregulation
Transplant Research Program, Boston Children's Hospital, Boston, MA.
The immunogenicity of graft microvascular endothelial cells (ECs) has immense biological significance in the modulation of the local intragraft microenvironment. EC may either support Teffector…2018 American Transplant Congress
Rapamycin Impairs Human Endothelial Cell Alloimmunogenicity Independent of PD-1/PD-1 Ligand Inhibitory Signaling
Department of Surgery, Duke University Medical Center, Durham, NC.
Rapamycin prevents costimulation blockade (CoB)-resistant rejection in mice and primates, and early human data suggests a similar salutary effect. We have hypothesized that one mechanism…2018 American Transplant Congress
Genome Wide Non-HLA Alloimmunity Contributes to Graft Loss after Kidney Transplantation
BackgroundChronic rejection is the main cause of renal transplant loss after the first year and has mostly been attributed to alloimmune responses against human leukocyte…2018 American Transplant Congress
Not All HLA Mismatches Are Equal: Determining the Relative De Novo DSA Induction Capacity of HLA Mismatches
We studied the immunogenicity, defined as the development of de novo DSA (dnDSA), of HLA-A, -B, -DR and -DQ MM (serological) in a cohort of…2018 American Transplant Congress
Anti-IdeS Antibodies in IVIg and Its Effect on IdeS Activity
ObjectiveEvaluate how and why intravenous gamma globulin (IVIg) affects IdeS-cleavage of IgG.IntroductionIgG degrading enzyme of Streptococcus pyogenes (IdeS) cleaves human IgG in two steps, first…2018 American Transplant Congress
The Relative Immunogenicity of HLA Mismatches in Adult Liver Transplant Recipients
Determining the immunogenicity of HLA mismatches (MM) may help preventing the appearance of de novo DSA (dnDSA) and avoiding antibody-mediated injuries.We studied the development of…2018 American Transplant Congress
Ex-Vivo Pretreatment of Islets with Mitomycin-C Have a Potential to Induce Specific Immune Response for Peripheral Tolerance
Hepato-Biliary-Pancreatic and Transplant Sugery, Fukushima Medical University, Fukushima, Japan.
Background.Our previous study demonstrated that ex-vivo Mitomycin-C(MMC) pretreatment of islets reduced immunogenicity, enhancing graft survival without immunosuppression(IS). However, it is still unclear whether donor specific…
