Antibody-Suppressor CD8+ T Cells Ameliorate Antibody-Mediated Rejection Following Kidney Transplant in Mice
1Ohio State University, Columbus, OH, 2Nationwide Children's Hospital, Columbus, OH
*Purpose: We previously reported the novel alloantibody suppressor activity of alloprimed CXCR5+IFN-γ+CD8+ T cells following hepatocellular transplant in mice. We utilized a murine kidney transplant…2020 American Transplant Congress
Formation Of Artificial Blood Vessels Using ECM In 3D Bioprinting
Foundation of Research and Science Development, Warsaw, Poland
*Purpose: Development of fully functional blood vessels in expanding field of artificial tissues and organs for transplantations in regenerative medicine is fundamental to provide proper…2020 American Transplant Congress
Transcriptomic Profiling of Paired Serum and Biopsy Samples from FSGS Patients
*Purpose: Pathogenesis and molecular footprints of focal segmental glomerulosclerosis (FSGS) after kidney transplantation whether it is primary or secondary is unknown. Herein, we studied a…2020 American Transplant Congress
Modulating ITK Signaling Facilitate Allogeneic Skin Engraftment and Clear LCMV Viruses by Regulating IRF-4, JAK STAT and Eomes Expression
*Purpose:Solid organ transplantation is a life-saving procedure to treat end-stage organ failure. However, transplantation of organs between genetically distinct individuals results in acute graft rejection…2020 American Transplant Congress
The Effect of Undernutrition and Immunosuppression on Cytomegalovirus Specific T Cell Responses
1Pediatrics, Duke University, Durham, NC, 2Surgery, Duke University, Durham, NC
*Purpose: Cytomegalovirus (CMV) infection remains a significant issue in transplantation, especially in those who are undernourished. While undernutrition is associated with impaired T cell immunity…2020 American Transplant Congress
Pregnancy Alloimmunization Increases the Clonality of the Endogenous Treg Repertoire
University of Pennsylvania, Philadelphia, PA
*Purpose: Pregnancy is a common immune sensitizing event, which creates an access barrier to organ transplantation and can impact transplant outcomes. While most research has…2020 American Transplant Congress
B Cell Depletion with Anti-CD20 mAb Exacerbates Anti-Donor CD4+ T Cell Responses in Highly Sensitized Transplant Model
Gastroenterological and Transplant Surgery, Hiroshima University, Hiroshima, Japan
*Purpose: Preformed donor-specific anti-human leukocyte antigen antibodies (DSAs) have been associated with detrimental effects in transplant recipients. To eliminate preformed DSAs, we desensitized DSA-positive recipients…2020 American Transplant Congress
Torc1 Inhibition Protects Activated Human Regulatory T Cells from Self-Inflicted Damage via Granzyme B
Transplantation Research Center, Brigham and Women's Hospital, Harvard Medical School, Boston, MA
*Purpose: The use of Regulatory T cells (Tregs) in adoptive cell therapy has been hindered by their short survival following their adoptive transfer. We have…2020 American Transplant Congress
Tissue Resident Memory T Cells in Mouse Renal Transplantation
1Starzl Transplantation Institute, Pittsburgh, PA, 2American University of Beirut, Beirut, Lebanon
*Purpose: The newly identified tissue resident subset of memory T cells (TRM) provides immune surveillance in the tissue and first response against infections. They are…2020 American Transplant Congress
Missing Self Increases the Incidence of Microvascular Inflammation after Kidney Transplantation
*Purpose: Anti-HLA donor-specific antibodies (HLA-DSA) are often absent in serum of kidney allograft recipients with biopsies demonstrating microvascular inflammation (MVI), the histological hallmark of antibody-mediated…
