Screening of RhoA/ROCK Inhibitors for the Ability to Prevent Chronic Rejection of Mouse Cardiac Allografts
Objectives. Chronic rejection of transplanted organs is a major obstacle in human organ transplantation. Although the mechanisms of chronic rejection are poorly understood it is…2018 American Transplant Congress
Mitochondrial Autophagy Proteins Bnip3 and Nix Maintain Memory B Cell Survival
Despite the use of immunosuppressive drugs, allograft rejection remains a major hurdle for the long-term success of organ transplants. Burgeoning evidence implicates memory B cells…2018 American Transplant Congress
Lymph Node Stromal Laminins Affect Graft Survival through Regulation of CD4 T Cell Proliferation and Migration
University of Maryland, Baltimore, MD.
Background: Our prior studies demonstrated that tolerance and immunity are associated with differential expression of lymph node (LN) stromal laminins α4β1γ1 (411) and α5β1γ1 (511),…2018 American Transplant Congress
Lymphotoxin Beta Receptor Modulation in Lymphatic Endothelial Cells Alters Regulatory T Cell Dynamics
Background:Lymphotoxin beta receptor (LTβR) mediated signaling in lymphatic endothelium cells (LEC) is important for migration of regulatory T cells (Treg) to afferent lymphatic vessels (LV)…2018 American Transplant Congress
Mechanisms of DEPTOR Function in CD4+ T Cell Subsets
We have previously observed that the cell intrinsic modulatory protein DEPTOR (DEP) stabilizes Foxp3 expression, enhances Treg function and inhibits Treg dedifferentiation. In vivo, sustained…2018 American Transplant Congress
T cell Phenotypes Predict Infectious Risk in Transplanted Children
AIM: Current monitoring strategies do not adequately differentiate infection from complications such as allograft rejection (AR). We aimed to identify peripheral T cell phenotypes that…2018 American Transplant Congress
Immune Phenotyping in a Pediatric Multicenter Transplant Study: Suitability of a Pre-Formulated Dry Antibody Panel System
Background:Flow cytometric immune-phenotyping is influenced by cryopreservation and inter-laboratory variability limiting comparability in multi center studies. The Duraclone™ system (DC) provides optimized pre-mixed dry antibody…2018 American Transplant Congress
DNA Methylation Age and Differential Patterns of DNA Methylation in Older Compared with Younger Kidney Transplant Recipients
David Geffen School of Medicine at UCLA, Los Angeles, CA.
Introduction: Older transplant recipients experience increased rates of infection and death, but decreased rates of rejection, suggesting a role of immune dysfunction. Analysis of DNA…2018 American Transplant Congress
Patients Converted to Belatacept Show Different Immunophenotyping Compared with De Novo Belatacept-Treated Patients
The incidence of adverse clinical events mainly in early, but not late post-transplantation such as an increased rate of acute rejection precludes the use of…2018 American Transplant Congress
The Neutrophil to Lymphocyte Ratio is Confounded by MELD in Hepatocellular Carcinoma Patients Undergoing Liver Transplantation
Department of General Surgery Digestive Disease Institute, Cleveland Clinic, Cleveland, OH.
Background: Biological markers such as the pre-operative neutrophil to lymphocyte ratio (NLR) have been suggested to be valuable indicators of recurrence and overall survival after…
