Late Renal Xenograft Failure Is Antibody-Mediated: Description of the Longest-Reported Survival in Pig-to-Primate Renal Xenotransplantation.
Introduction. Xenotransplantation has the potential to alleviate the organ supply shortage, yet pig-to-primate renal xenotransplant has met limited success due to natural preformed anti-pig antibody.…2016 American Transplant Congress
IFN-γ and Contact-Dependent Cytotoxicity Are Rate-Limiting for NK Cells in a Model of Antibody-Mediated Chronic Rejection.
BACKGROUND. Natural killer (NK) cells are key components of the innate immune that contribute to acute and chronic graft rejection. After engagement with antibody, NK…2016 American Transplant Congress
Ibrutinib Suppresses Alloantibody Responses in A Mouse Model of Allosensitization: A Preliminary Report.
CTC/Surgery, Cedars-Sinai Medical Center, Los Angeles, CA.
Background Ibrutinib is a Bruton tyrosine Kinase (BTK) antagonist that inhibits B cell receptor (BCR) signaling, therefore blocking B cell activation. Ibrutinib is approved by…2016 American Transplant Congress
Renal Fibroblast Activation and Survival by Anti-MHC Class I Antibody: The Role of mTOR Signaling Pathway.
Medicine/Surgery, University of Alabama at Birmingham, Birmingham, AL.
Background: Antibody-mediated injury (AMI) is an important contributor to late kidney allograft loss, and is accompanied by interstitial fibrosis (IF) and tubular atrophy (TA). However,…2016 American Transplant Congress
The Role of B Cells in Liver Transplant Tolerance.
Scarcely one would argue that donor-specific B cells and antibodies contribute to rejection of transplants. However, studies published in the past few years have provided…2016 American Transplant Congress
Recall Alloantibody Production Is Driven by CD138+ Cells Proliferating in the Spleens: An Indication for Long-Lived Plasma Cell Activities and Potential Therapeutic Target.
Comprehensive Transplantation Center/Surgery, Cedars-Sinai Medical Center, Los Angeles, CA.
Background Donor-specific antibodies (DSA) generated in recall responses are produced by long-lived plasma cells (L-PC) residing in the bone marrows (BM). Mechanisms of L-PC activation,…2016 American Transplant Congress
Alloantibody Suppression by Bruton Tyrosine Kinase Antagonist Ibrutinib Is Associated with a Moderate Splenic B-Cell Reduction.
Comprehensive Transplantation Center/Surgery, Cedars-Sinai Medical Center, Los Angeles, CA.
Background Bruton tyrosine kinase (Btk) is specifically required for activation of the B-cell antigen receptor signaling pathway that contributes to the initiation and maintenance of…2016 American Transplant Congress
The Role of HLA Class II Antibody in Endothelial Cell Activation and Allograft Rejection.
Background: Antibody-mediated rejection is one of the major causes of chronic rejection. This is mediated by endothelial cell activation, a process of endothelium microvascular inflammation…2016 American Transplant Congress
Interaction Between Kidney Tissue Proteome and Humoral Immunity in Antibody Mediated Rejection.
PURPOSE: Antibody-mediated rejection (AMR) is caused by antibodies against human leukocyte antigens (HLA) on graft endothelium, and non-HLA antibodies that target endothelial and epithelial proteins.…2016 American Transplant Congress
Impact of CXCR4/CXCL12 Blockade on Normal Plasma Cells In Vivo.
Department of Surgery, Division of Transplant Surgery, Mayo Clinic, Rochester, MN.
Introduction:Plasma cells (PCs) are a major source of alloantibody in transplant patients.They are resistant to current therapy. Since receptor/ligand interactions in the stromal environment are…
