Transplantation of Chimeric Cells of Myoblast and Mesenchymal Stem Cell Origin for Restoration of Muscle Function.
University of Illinois at Chicago, Chicago
Background: Allogeneic stem cell therapies aim to restore muscle tissue after traumatic loss or muscular dystrophies. Limited engraftment due to rejection is a major challenge.…2017 American Transplant Congress
Assessment of Donor-Reactive T-Cell Immunity by the Novel Urine Cell-Derived Alloantigen Assay Allows Prediction of Acute Rejection in Renal Transplant Patients.
Presensitization and donor-specific immunity play a major role in acute and chronic rejection of kidney transplant patients. While assessment of humoral sensitization is well standardised…2017 American Transplant Congress
CD4 T Cell Depletion Mitigates Ischemic Hepatocellular Damage and Promotes Immune Regulation in Mouse Liver Allografts.
Background: Extended cold preservation contributes to organ ischemia-reperfusion injury (IRI), which stimulates host allo-reactivity, leading to inferior clinical outcomes. We have shown that CD4+ T…2017 American Transplant Congress
Type-1 Interferon Impairs the Immunoregulatory Activity of IL-10: A Mechanism in the Abrogation of Transplant Tolerance.
Plastic Surgery, Johns Hopkins University. School of Medicine, Baltimore, MD
PurposeA growing body of experimental evidence shows that engagement of toll like receptors (TLR) can abrogate or revert the tolerogenic effect of “costimulation blockade” in…2017 American Transplant Congress
Phenotypic and Functional Assessment of T Cell Alloimmunity After Liver Transplantation.
In addition to its metabolic functions, the liver is also an immunologically active organ. Liver transplant recipients are often maintained on less immunosuppression when compared…2017 American Transplant Congress
Does an Indeterminate Result on Pre-Transplantation Tuberculosis Interferon Gamma Release Assay Predict Risk for Post-Transplantation Infection or Rejection?
Purpose: Most centers use interferon gamma release assays (IGRA) to screen for latent TB in transplant candidates. Some of them have an indeterminate result due…2017 American Transplant Congress
Loss of Bat3 Could Promote Transplant Tolerance by Regulating CD4 + T Cells Function.
Objective: To explore the effect of Bat3 on T cells and its function in transplant tolerance inductionMethodsWe generated Bat3flox/flox CD4-Cre + mice, sorted WT and…2017 American Transplant Congress
CD4+CD28null T Cells Require IL-15 & IL-21 to Become Alloresponsive.
IntroductionAgeing and a pro-inflammatory milieu, such as present in patients with end-stage renal disease, are important drivers of increased T-cell differentiation, which is accompanied by…2017 American Transplant Congress
A Prospective Observational Study to Evaluate Use of a Panel of Reactive T Cell (PRT) Assay as a Pre-Transplant Marker of Rejection in Kidney Transplant Recipients.
Background:To assess risk of T cell mediated acute rejection a recently developed assay uses a panel of reactive T cell lines (PRT) to measure recipient…2017 American Transplant Congress
Prospective Randomized Trial for Predicting CMV Infection According to Baseline CMV-Specific T-Cell Immunity in Kidney Transplant Patients.
Background: Despite the use of either anti-viral prophylaxis (PF) or preemptive (PE) therapy given based on donor/recipient IgG-serostatus, Cytomegalovirus (CMV) reactivation persists after kidney transplantation…
