The Effect of Daratumumab (Dara, Humanized Anti-CD38 Monoclonal Antibody) on Immune Cells In Vitro and in a HLA-Sensitized Kidney Transplant Patient (HS KTx Pt) Desensitized (DES) with Dara
*Purpose: Antibody-Mediated Rejection (ABMR), primarily mediated by B cells, plasma cells (PC) and antibodies (Ab), is an obstacle for successful transplantation in HS KTx Pts.…2021 American Transplant Congress
Selective Bcl-2 Inhibition for Induction of Mixed Chimerism and Renal Allograft Tolerance without Myelosupression
*Purpose: Immunologic tolerance of renal allograft has been achieved by induction of hematopoietic chimerism through donor bone marrow transplantation (DBMT). The myeloablative and genetic toxicity…2021 American Transplant Congress
Intrarenal B-cell Activating Factor (BAFF) Levels are Increased in Transplant Glomerulopathy
University of Wisconsin Madison, Madison, WI
*Purpose: Transplant glomerulopathy (TG), a key feature of chronic active antibody-mediated rejection (caABMR), is associated with allograft failure. B-cell activating factor (BAFF) is a cytokine…2021 American Transplant Congress
Evaluation of Rituximab-abbs in Renal Transplant: A Case Series
*Purpose: Biosimilars are FDA-approved alternatives to cost-prohibitive biologics, with no clinically meaningful differences in safety, purity, and potency. Rituximab-abbs, a biosimilar to rituximab, has labeled…2021 American Transplant Congress
Contribution of T-bet Expressing CD27+ CD21- Activated Memory B Cells Poised for Plasma Cell Differentiation to Antibody-mediated Rejection of Kidney Transplants
*Purpose: Alloimmunity triggered by donor-specific antibodies (DSAs) and ensuing development of antibody-mediated rejection (ABMR) are detrimental to organ transplants. Yet, the cellular states underlying B…2021 American Transplant Congress
TOLS are Novel Regulatory TLOs with A B Cell Signature
1Massachusetts General Hospital, Boston, MA, 2Co-Senior Authors, Boston, MA
*Purpose: Our previous studies suggest that a DBA/2 kidney graft is accepted by a MHC-fully mis-matched C57/BL6 recipient. Accepted renal allografts exhibited lymphoid like structures…2020 American Transplant Congress
Tertiary Lymphoid Organs in Renal Chronic Allograft Rejection
Starzl Transplantation Institute, Pittsburgh, PA
*Purpose: Chronic allograft rejection remains a major obstacle to long-term allograft survival. Tertiary lymphoid organs (TLOs) are ectopic lymphoid structures that arise in non-lymphoid tissues…2020 American Transplant Congress
Transitional B Cell Cytokines for the Early Prediction of Long-Term Renal Allograft Decline
1Starzl Transplantation Institute, UPMC, Pittsburgh, PA, 2UCL, London, London, United Kingdom
*Purpose: Early prediction of allograft loss using potentially modifiable risk factors is vital for conceiving novel therapeutic interventions to improve outcomes.*Methods: In this prospective, multicenter…2020 American Transplant Congress
Erythropoietin Reduces Alloantibody Formation by Inhibiting T Follicular Helper Cells
*Purpose: Donor-specific antibodies (DSA) develop in a significant minority of transplant recipients and are associated with increased morbidity and mortality, underscoring the need to identify…2020 American Transplant Congress
Generation of Insulin-Producing Cells via Multiplex Epigenetic Engineering of Human Somatic Cells in 2 Weeks
*Purpose: Stem cell-derived β-cells not only promise a renewable supply of insulin-producing cells with negligible immunosuppression but may also provide a substrate for the identification…
