Rapid Emergence of CD28null Cells Following Ex Vivo Restimulation Is Associated with Belatacept Resistant Rejection.
Emory Transplant Center, Atlanta, GA.
Numerous studies have implicated donor-reactive memory T cells in mediating costimulation blockade resistant rejection (CoBRR) following treatment with belatacept. In humans, these memory T cells…2016 American Transplant Congress
The Presence of CMV-Specific T-Cells in CMV-Seronegative Kidney Transplant Recipients Predicts Outcome After Kidney Transplantation.
CMV-seronegative kidney transplant recipients (KTRs) from CMV-seropositive donors are at highly increased risk of primary CMV-infection with associated inferior outcomes after kidney transplantation. Presence of…2016 American Transplant Congress
Exposure Analysis for the Composite Efficacy Endpoints in the US92 Phase 3 Kidney Transplantation Trial to Understand Center Effects.
The US92 study determined whether, in de novo renal transplant patients, concentration-controlled everolimus (EVR) with reduced dose tacrolimus (RTAC) is non-inferior compared to CellCept®, (mycophenolate…2016 American Transplant Congress
miR-21 in Chronic Allograft Vasculopathy.
Background. Heart transplantation is the most effective therapy to prolong life expectancy in patients with end-stage heart failure. However, despite much progress in the field,…2016 American Transplant Congress
Urine-Derived Cell Lines as a Novel Tool for Monitoring Allo-Reactivity in Kidney Transplant Patients.
Reactivity of the immune system against donor antigens determines transplant-rejection after transplantation, and analyzing the alloimmune response has been shown to predict acute rejection in…2016 American Transplant Congress
High PD-L1/CD86 MFI Ratio and IL-10 Secretion Characterize Maturation-Resistant Human Regulatory Dendritic Cells (DCregs) Generated for Clinical Testing in Transplantation.
Regulatory dendritic cells (DCregs) have shown considerable potential for safe and effective prolongation of allograft survival in pre-clinical models. In humans, DCregs with purity >84%…2016 American Transplant Congress
Diabetes Mellitus Predicts Outcome in Obesity After Kidney Transplantation.
Obesity has been associated with an increased risk of allograft loss and death from infection in kidney transplant recipients (KTRs). Therefore, previous studies suggested bariatric…2016 American Transplant Congress
Allo-Specific Memory B Cell Recall Responses Are Dependent on B Cell Autophagy.
B cells, and in particular, memory B cells (Bmem) are sources of donor specific antibodies (DSA) that cause allograft injury. Understanding requirements for Bmem function/survival…2016 American Transplant Congress
Activation of Alloreactive T Cells by Allogeneic Exosomes and Cells Cross-Dressed with Allogeneic MHC Molecules.
Our recent studies have documented the presence of high numbers of recipient antigen presenting cells (APCs) displaying donor MHC molecules (cross-dressed) on their surface after…2016 American Transplant Congress
Fate of Endogenous Alloreactive B Cells in Transplant Tolerance.
The conceptual underpinning of our studies is that robust tolerance requires multiple mechanisms to enforce functional quiescence of alloreactive T and B cells. While much…
