NK Cells Play a Critical Role in Mediating Inflammation and Graft Failure During Antibody-Mediated Rejection of Kidney Allografts.
While the incidence of antibody-mediated kidney graft rejection has increased, the key cellular and molecular participants underlying this graft injury remain unclear. We have previously…2016 American Transplant Congress
Early Alloantibody Responses Against Donor MHC Class I and Class II Molecules Are Differentially Affected by Prolonged Cold Ischemia Storage of Renal Allografts.
Immunology, Cleveland Clinic Foundation, Cleveland, OH.
Prolonged cold ischemia storage (CIS) of donor transplants is a major risk factor for acute and chronic graft tissue injury. Despite strong clinical correlations between…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
The Fine-Tuning of CXCL8 Protects Kidney Against Ischemia-Reperfusion Injury in Mice Lacking MicroRNA-146a.
Acute kidney injury leads to the development of tubular injury and interstitial inflammation that need to be controlled to avoid fibrosis development. We hypothesized that…2016 American Transplant Congress
Fate of Endogenous Alloreactive B Cells in Transplant Tolerance.
The conceptual underpinning of our studies is that robust tolerance requires multiple mechanisms to enforce functional quiescence of alloreactive T and B cells. While much…2016 American Transplant Congress
Administration of IL-33 Before Allogeneic Stem Cell Transplantation Expands Recipient Treg That Prevent Graft- vs. Host Disease.
Background: During allogeneic hematopoietic cell transplantation (alloHCT), non-hematopoietic cell IL-33 is augmented and released by recipient conditioning to promote Type 1 alloimmunity and lethal acute…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
Tissue Inhibitor of Metalloproteinase-3 (TIMP-3) Protects Against Loss of Hepatic Integrity After Ischemia-Reperfusion Injury.
Surgery, The Dumont-UCLA Transplant Center, Los Angeles, CA.
Liver ischemia-reperfusion injury (IRI) remains a challenging problem in clinical orthotopic liver transplantation (OLT). Tissue inhibitor of metalloproteinases-3 (TIMP-3) is an extracellular matrix (ECM)-associated protein…2016 American Transplant Congress
B Lymphocytes Prevent Transplantation Tolerance in NOD Mice by Limiting CD4 Treg Function.
Pediatrics, Vanderbilt University, Nashville, TN.
IntroductionType 1 Diabetes is a significant barrier to islet transplant as grafts are subject to both alloimmunity and recurrent autoimmunity. No better is this clinical…2016 American Transplant Congress
Novel Function of CD4+ T Cell DEPTOR in Treg Homeostasis and Alloimmunity.
DEPTOR, a recently described modulator of PI-3K/mTOR signaling, is expressed by CD4+ T cells, and functions to modulate CD4+ Teff cell differentiation. Upon CD4+ T…
