MHC Molecule-Ablated Human Endothelial Cells Form Alloimmune-Evasive Microvessels
*Purpose: “Off the shelf” tissue-engineered organs will require use of allogeneic cell sources. Allogeneic human endothelial cells (ECs), necessary for organ perfusion, can initiate graft…2019 American Transplant Congress
In Vitro Model to Study the Effect of Irradiation Preconditioning on Alloimmune Responses: Development of Potential Predictive Markers
Radiation Oncology, Dana-Farber Cancer Institute, Boston, MA
*Purpose: Pre-conditioning using total body irradiation prior to HSCT is a well-established regimen for patients with hematological malignancy. However, irradiation (IR) elicits not only immunosuppressive…2019 American Transplant Congress
Next Gen ABO Antibody Assessment: Development of a Bead-Based ABO Antibody Detection Assay
*Purpose: Accurate characterization of ABO antibodies (ABO-Ab) is critical to assess their impact in ABO incompatible (ABOi) transplantation. The current ABO-Ab detection method using erythrocyte…2019 American Transplant Congress
Intra-Operative Kinetics of Anti-HLA Antibodies in Simultaneous Liver-Kidney Transplantation
Baylor College of Medicine, Houston, TX
*Purpose: In simultaneous liver-kidney transplantation (SLKT) in highly-sensitized patients, donor specific anti-HLA antibodies (DSA) can be present prior to transplant leading to positive crossmatch, yet…2019 American Transplant Congress
Report of 20 HLAMatchmaker Eplets Present on Denatured Class I HLA Molecules
*Purpose: The purpose of this report is to describe 20 class I HLA eplets, herein called FakEplets, present on denatured HLA molecules.*Methods: The study included…2018 American Transplant Congress
Temporal Variability of IgG Subclasses
Northwestern University, Chicago; Lurie Children's Hospital, Chicago.
The temporal model of IgG subclass switching supports sequential IgG conversion; however, the diversity of previously stimulated B cells is known to shape responses in…2018 American Transplant Congress
Anti-Thymocyte Globulin Directly Binds and Functionally Inhibits Allo-Regulatory Myeloid Derived Suppressor Cells
Surgery and Immunology, University of Maryland, Baltimore, MD.
BACKGROUND: Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of naturally occurring, immunosuppressive cells that may be exploitable in transplantation.There are only a few incomplete…2018 American Transplant Congress
Regulatory Dendritic Cell (DCreg) Cell Infusion in Living Donor Liver Transplantation
Starzl Transplantation Institute, University of Pittsburgh School of Medicine, Pittsburgh, PA.
Purpose: We have embarked on a first-in-human phase I/II safety and preliminary efficacy trial of donor-derived regulatory dendritic cells (DCreg) in living donor liver transplantation…2018 American Transplant Congress
MICA/B Polymorphisms and the Relationship of the Matching Degree between MICA/B and HLA of Related Donor-Recipient Pairs in Allo-HSCT
Beijing 307 Hospital, Beijing, China.
Objective: To explore the distribution characteristics of MICA/B gene polymorphism in the Han Chinese and the relationship of the matching degree between MICA/MICB and HLA…2018 American Transplant Congress
Increase on Regulatory Cells in Kidney Transplanted Patients Presenting Donor-Specific Antibodies
The role of anti-HLA donor specific antibodies (DSA) in increasing the risk of graft rejection is known. Nevertheless, not all patients with DSA develop rejection…
