Beta2-Adrenergic Receptor Activation Prolongs Survival of Vascularized Composite Tissue Allotransplants in a Murine Model
*Purpose: Transplantation of faces, hands, and limbs using vascularized composite allotransplantation (VCA) has faced significant challenges hindering its routine implementation in the clinic. One critical…2019 American Transplant Congress
ZFYVE21 is a Novel Complement-Induced Rab5 Effector Protein Mediating Cardiac Allograft Vasculopathy
*Purpose: Complement promotes vascular inflammation in transplant organ rejection, a process leading to cardiac allograft vasculopathy. In this study, we identify a new Rab5 effector…2019 American Transplant Congress
High Urinary Neutrophil Gelatinase Lipocalins (NGAL) Levels in Kidney Perfusates as Predictor of a Better Renal Function
DIMES, S.Orsola-Malpighi Hospital, Bologna University, Bologna, Italy
*Purpose: Neutrophil gelatinase-associated lipocalin (NGAL) has recently emerged as a biomarker of different conditions, but the biological role remains unclear. We hypnotized that NGAL has…2019 American Transplant Congress
Senescent Cell Clearance with Senolytic Drugs Improves Cardiac Allograft Survival by Targeting mt-DNA Mediated Immune Responses
*Purpose: Older organs represent an underutilized potential. We dissected alloimmune responses when transplanting older organs and tested if the depletion of senescent cells in older…2019 American Transplant Congress
Pre-Transplant Donor-Specific IFN-γ ELISPOT as a Predictor of Allograft Rejection: A Diagnostic Test Accuracy Meta-Analysis
*Purpose: Pre-transplant interferon-γ (IFN-γ) enzyme-linked immunospot (IFN- γ ELISPOT) has been proposed as a tool to quantify alloreactivity of memory T cells and estimate the…2018 American Transplant Congress
The Inhibitory Effect of Plasma on Activation of Lymphocytes from Kidney Transplants is Significantly More Severe in Tacrolimus Based Regimen: What Implications for Plasma Exchange Role in Anti-Rejection Therapy?
Background:Reduction of lymphocyte proliferation by human plasma has been previously reported. Reduced activation of lymphocytes of patients on immunosuppressive drugs is well documented. However, trial…2018 American Transplant Congress
Sensing T Cell Killing Activity with Granzyme B Activity Probes
Purpose: We developed activity-based probes that sense Granzyme B (GzmB) activity during alloreactive T cell killing of donor cellsMethods: FITC-labelled GzmB substrate (IEFDSG) was synthesized…2018 American Transplant Congress
B-Cell Depletion with Rituximab Exacerbates Anti-Donor CD4+ T-Cell Responses in Patients with Donor-Specific Anti-Human Leukocyte Antigen Antibodies
Gastroenterological and Transplant Surgery, Hiroshima University, Hiroshima, Japan.
Background: It has been reported that preformed donor-specific anti-human leukocyte antigen antibodies (DSAs) were associated with poor graft outcomes in kidney transplant recipients. To eliminate…2018 American Transplant Congress
Donor T Cells Undermine the Graft-Protective Effect of DST Plus Anti-CD154
Plastic Surgery, Johns Hopkins University, Baltimore, MD.
Costimulation blockade (CoB) regimens are a promising immunomodulatory strategy to prevent transplant rejection. However, their efficacy is affected by multiple factors, including still unknown ones.…2018 American Transplant Congress
Galangin Promotes Treg Development and Function
Introduction: FoxP3+ Treg cells are central in controlling immune responses and transplant tolerance. CD73 (ecto-5'-nucleotidase), which serves to convert AMP to adenosine, is essential for…
