Natural Killer Cells Express Significantly More CD16 during Chronic Active Antibody Mediated Rejection Which is Not Caused by a Single Nucleotide Polymorphism within the CD16 Gene
Erasmus MC, Rotterdam, Netherlands
*Purpose: Chronic-active antibody mediated rejection (c-aABMR) is the leading cause of long-term renal allograft loss. Fc-receptor CD16 bearing natural killer (NK) cells may be involved…2019 American Transplant Congress
Back Signaling of HLA Class I Molecules and NK Cell Receptor Ligands in Renal Epithelial Cells Contributes to the Rejection-Specific Microenvironment
*Purpose: During the last years, diverse harming mechanisms of donor-specific antibodies (DSA) to endothelial cells have been studied accompanied by an emerging evidence of NK…2019 American Transplant Congress
CCR5-Mediated Recruitment of NK Cells to the Kidney is a Critical Step for Host Defense to Candida albicans Infection
*Purpose: Candida albicans infection causes a high rate of mortality in immunocompromised or transplant patients. In this study, we investigated the role of CCR5 that…2019 American Transplant Congress
Broadly Profiling the Activation Status of Circulating Immune Cells in Chronic Active Antibody Mediated Rejetion Reveals Increased CD38 and CD16 Expression on Monocytes and NK Cells
Erasmus MC, Rotterdam, Netherlands
*Purpose: Chronic-active antibody mediated rejection (c-aABMR) contributes significantly to late renal allograft failure. Non-invasive biomarkers of c-aABMR are currently not available but could be valuable…2019 American Transplant Congress
EBV Latent Proteins Encode for Peptides That Prevent Natural Killer Cell Inhibition
*Purpose: Epstein-Barr virus (EBV) infects more than 90% of adults worldwide and is associated with several malignancies, including post-transplant lymphoproliferative disorder (PTLD). Although EBV infection…2018 American Transplant Congress
Th17 and NK Responses Are Differentially Induced in Renal Allografts According to Recipient Murine Cytomegalovirus Dose and Strain
Purpose: To study the impact of cytomegalovirus (CMV) recipient positive (R+) serostatus upon renal allograft injury, murine CMV (MCMV) D+/R+ kidney transplants using recipients infected…2018 American Transplant Congress
Donor-Specific Antibody Mediates Chronic, but Not Acute, Kidney Allograft Rejection in the Absence of Natural Killer Cells
Immunology and Glickman Urological Institute, Cleveland Clinic, Cleveland, OH.
The incidence of antibody-mediated kidney graft rejection continues to increase. We previously reported that dysregulated donor-specific antibody (DSA) responses were induced in B6.CCR5-/- mice transplanted…2018 American Transplant Congress
Peptides Encoded by EBV Latent Cycle Proteins Affect NK Cell Reactivity
Department of Surgery, Stanford University School of Medicine, Stanford, CA.
Introduction: Epstein–Barr virus (EBV) infects more than 90% of adults worldwide and is associated with several malignancies, including post-transplant lymphoproliferative disorder (PTLD). Although EBV infection…2018 American Transplant Congress
NK Cells with a Lung-Resident Phenotype Represent the Most Prominent Donor Passenger Leukocyte Subset after Clinical Lung Transplantation
ObjectivesDonor passenger leukocytes in peripheral blood of recipients after lung transplantation have been described long time ago. However, kinetics, distribution of T vs. NK cells,…2018 American Transplant Congress
The Role of NKT Cell /IL-17 Axis in the Autoimmune Lupus Nephritis
CD1d-restrictive NKT cells may modulate various chronic autoimmunity through secreting multiple cytokines, but the functional relationships between the different subpopulation still are poorly understood. The…
