Operational Tolerance in Intestinal Transplantation: A Proven Possibility.
A The purpose of this study is to immunologically characterize the first operationally tolerant intestinal transplant (ITx) patient known to date.B Flow cytometry and rtPCR…2017 American Transplant Congress
Innate Lymphoid Cells Play a Critical Role in Regulating Allograft Homeostasis in Human Intestinal Transplantation.
Transplant, MedStar Georgetown Transplant Institute, Washington, DC
A. The role of recently discovered innate lymphoid cells (ILCs) in intestinal transplant (ITx) patients is poorly understood. Here, we postulate that intestinal ILC subsets…2017 American Transplant Congress
CD16a-Activated NK Cells in ABMR Are Highly Similar to CD3-Activated Effector T Cells in TCMR.
University of Alberta, Edmonton, Canada
BACKGROUND: NK cell CD16a and T cell CD3 activate shared pathways. Since NK cell CD16a activation occurs in antibody-mediated rejection (ABMR) and T cell CD3…2017 American Transplant Congress
The Role of Natural Killer Cells in Recognition and Killing of Stem Cells and Stem Cell-Derived Hepatoblasts.
Surgery, Stanford University School of Medicine, Stanford, CA
The generation of stem cell-derived hepatocytes holds promise as a cell-based treatment for liver disease. However, the immune response to stem cell-derived grafts is poorly…2017 American Transplant Congress
Endocapillary NK Cells Are Increased in Indication Renal Transplant Biopsies with Antibody and T Cell Mediated Rejection.
Pathology, University of Michigan Medical School, Ann Arbor, MI
Detection of NK cell transcripts in renal transplant biopsies is associated with antibody mediated rejection (AMR). Similarly, quantification of endocapillary NK cells in paraffin tissue…2017 American Transplant Congress
The Degree of NK Cell Activation Determines the Ability of Donor-Specific Antibodies to Mediate Acute vs. Chronic 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…2017 American Transplant Congress
Adoptive Immunotherapy with Liver Allograft-Derived Lymphocytes Compensate for the Susceptibility to Post-Liver Transplant Blood Stream Infection Associated with FCGR3A SNP.
Gastroenterological and Transplant Surgery, Hiroshima University, Hiroshima, Japan
By studying the single nucleotide polymorphisms (SNPs) of FCGR2A and FCGR3A, genes encoding FcγR, we previously demonstrated the significantly higher incidence of blood stream infections…2017 American Transplant Congress
IVIg+Rituximab Desensitization (DES) Combined with Alemtuzumab (ATZ) Induction Does Not Increase Risk for Viral Infections (VIs) and Associated Complications in HLA-Sensitized (HS) Kidney Transplant Patients (KTx Pts).
Background: VIs represent significant morbidity factors in KTx pts. DES followed by KTx with ATZ induction increased successful Tx rates in HS pts, but may…2017 American Transplant Congress
IdeS, an IgG Endopeptidase, Effectively Cleaves Anti-CMV IgG, Resulting in Inhibition of Antibody (Ab)-Mediated NK Cell Activation in Kidney Transplant Patients (KTX Pts).
Background: Viral infections represent significant morbidity factors for KTx Pts. Ab-dependent cell-mediated cytotoxicity (ADCC) is a major pathway to eliminate virally infected cells and is…2017 American Transplant Congress
NKG2C+ NK Cell Adaptive Response and the Risk of Cytomegalovirus Infection in Kidney Transplant Recipients.
Cytomegalovirus (CMV) infection in kidney transplant recipients (KTR) has been associated with an increased risk of graft loss and reduced host survival. CMV promotes persistent…
