Selection and Stratification of Anti-HLA-A and HLA-B Sensitized Patients in Pig-to-Human Xenotransplantation
Introduction: Patients with anti-HLA-A and –B antibodies are difficult to match and represent a possible population for inclusion in pig-to-human xenotransplantation clinical trials. Donor specific…2018 American Transplant Congress
Stress-Related Exosomal MicroRNA Biomarkers Released by Human Islets during Transplantation
1Baylor Scott & White Research Institute, Dallas; 2Baylor Simmons Transplant Institute, Dallas.
Purpose: Pancreatic islets release noncoding microRNAs (miRNAs) upon damage and stress during islet transplant procedures. In this study, we sought to identify miRNAs released by…2018 American Transplant Congress
CD4+CD25bright Regulatory T Cells Prevent Acute Xenogeneic GVHD
Institute for Cellular Therapeutics, University of Louisville, Louisville, KY.
Graft-versus-host disease (GVHD) is a major complication and limitation to the broad application of hematopoietic stem cell transplantation. Cell therapy has emerged as a promising…2018 American Transplant Congress
Pancreas Decellularization Protocol – Comparison of Methods
Foundation of Research and Science Development, Otwock, Poland.
Background: Whole organ decellularization is gaining a lot of popularity since its development in tissue engineering. It is a process which allows to create complex…2018 American Transplant Congress
Biochemistry Profiles Following Pig-to-Nonhuman Primate Liver Xenotransplantation
Center for Transplantation Sciences, Massachusetts General Hospital, Boston, MA.
Objectives:Clinical progress in liver transplantation has increased the demand for organs, however, supply remains stagnant. Porcine liver xenotransplantation (LXT) would help address this imbalance. Here…2018 American Transplant Congress
Rhesus Monkey Have natural Antibody toward Swine That is Not Influenced by Allosensitization nor by Carfilzomib/tocilizumab
Surgery, Duke University, Durham, NC.
[Background] Pre-formed antibody is a substantial immunological barrier in organ transplantion. Antibodies to xenoantigens can lead to rapid antibody-mediated rejection (AMR) in xenotransplantation. We previously…2018 American Transplant Congress
Re-Endothelialization of Liver Xenografts Utilizing Human Endothelial Cells
1Surgery, University of Maryland, Baltimore, MD; 2Pathology, University of Maryland, Baltimore, MD.
Introduction:Acute antibody mediated rejection due to preformed antibodies present in human serum remains a hurdle to successful xenotransplantation. Xenograft vascular endothelium represents the initial site…2018 American Transplant Congress
The Effect of Intravenous Immunoglobulin on In Vitro Human Antibody Binding to Genetically-Engineered Pig Cells – Relevance to Clinical Xenotransplantation –
Background: Xenoreactive antibodies play an important role in xenograft rejection. Intravenous immunoglobulin (IVIG), which has anti-complement activity and contains anti-idiotypic antibodies, is widely used for…2018 American Transplant Congress
Successful Patency in Blood Conduits for an Artificial Kidney Membrane with Biocompatible Coatings
1VUMC, Nashville; 2UCSF, San Francisco.
BACKGROUND: An implantable artificial kidney may address the growing organ shortage and improve outcomes and quality of life for those with end stage renal disease.…2017 American Transplant Congress
