Multi-Targeting Desensitization Therapy Alters Peripheral B-Cell Homeostasis and Suppresses Recall Alloantibody Responses
CTC/Surgery, Cedars-Sinai Medical Center, Los Angeles, CA.
Purpose: Occurring of donor specific antibodies (DSA) is injurious to organ transplant. Development of immunotherapies to suppress DSA, therefore, has been one of the strategic…2018 American Transplant Congress
Analysis of Circulating CD38+/CD138+ Plasma Cells during Development of De Novo Donor Specific Antibody Responses
CTC/Surgery, Cedars-Sinai Medical Center, Los Angeles, CA.
Purpose: Donor specific antibodies (DSA) that emerge following transplantation are indicative of allogenic sensitization and a predisposing factor for antibody mediated rejection. Though various methods…2017 American Transplant Congress
Human Islet-Derived Extracellular Vesicles Stimulate CD14+ Monocytes Resulting in Proinflammatory Cytokine Production.
Department of Surgery, McGill University Health Centre, Montreal, QC, Canada
Introduction: The cellular events involved in the generation of an auto and allo-reactive immune response in recipients of islet transplantation are not well understood. In…2017 American Transplant Congress
Immunosuppressive Treatment Alters Gut Microbiota and Modified Gut Microbiota Affects Immune Status.
Department of Urology, Beijing Chaoyang Hospital, CCMU, Beijing, China
Objectives: Immunosuppressive therapies could change the host-microbial interactions, especially gut microbiota, which is an important component in systemic immunity. We evaluated the relationship between immunosuppression…2017 American Transplant Congress
BKV Clearance Time Correlates with T-Cell Receptor Repertoire Shape and Exhaustion State of BKV-Specific T-Cells in Renal Transplant Patients with Severe BKV Infection.
Reactivation of the BK polyomavirus is known to lead to severe complications in kidney transplant patients. The current treatment strategy relies on decreasing the immunosuppression…2017 American Transplant Congress
Increased T Cell Exhaustion in Dialysis Patients.
Transplantation Research Center, Brigham and Women's Hospital, Boston, MA
Infection is a major complication post-transplantation. Evaluating the immune system prior to transplant may allow better optimization of immunosuppression dose. T cell exhaustion has been…2017 American Transplant Congress
The Role of Anti-Neu5Gc IgM in Xenograft Antibody Mediated Rejection.
Background:Acute antibody mediated rejection due to preformed antibodies present in human serum remains a hurdle to successful xenotransplantation. Here, we measured anti-Neu5Gc-IgM antibody titers in…2017 American Transplant Congress
Effect of Two Anti-CD20 Abs on B Cell Depletion and Reconstitution in Non-Human Primates.
Background: B lymphocytes play a central role in host immunity, including antibody elaboration and antigen presentation, and B-cell depletion is being explored to modulate alloimmunity.…2017 American Transplant Congress
Reduced Expression of Membrane Complement Regulatory Protein CD59 on Leukocytes Following Lung Transplantation.
BackgroundCellular protection against unwanted complement activation is provided by expression of membrane-bound complement regulatory proteins including CD59. This protein prevents membrane attack complex formation and…2017 American Transplant Congress
In Depth Characterization of the Innate Immune Response in Transplant Recipients with EBV Viremia.
Background:Infection with Epstein-Barr virus (EBV) manifests as a spectrum of disease ranging from asymptomatic viremia to PTLD. Innate immune cells such as monocytes/macrophages, dendritic cells…
