Effects of Toll Like Receptor (TLR) Signaling on Murine Alloimmunity Are Modulated by Immune Cell Derived Complement
TLR signals prevent CD40L-blockade (MR1) induced murine transplant tolerance but mechanisms are incompletely understood. Based on previous findings that immune cell derived complement activation products…2015 American Transplant Congress
A Primary Cytomegalovirus Infection Post-Transplantation Has a Significant Impact on Circulating T Cells and Renal Allograft Function
Study's purpose: Cytomegalovirus (CMV)-infection may profoundly affect the peripheral T-cell compartment and is associated with T-cell ageing and generation of cytotoxic CD4+CD28null T cells. We…2015 American Transplant Congress
Absence of Nucleotide-Binding Oligomerization Domain-Containing Protein 1 and 2 Modifies Adaptive Immune Responses
Background:The NOD family of intracellular pattern recognition receptors (PRRs) plays a key role in immune responses to microbial and danger signals. This family of proteins…2015 American Transplant Congress
Tracking T Cell Fate After Antithymocyte Globulin (ATG) Immunotherapy in Infant Heart Transplant (HTx) Patients
Polyclonal T cell depletion with ATG is a common induction therapy in adult and pediatric transplantation. In adults, T cell recovery post-ATG involves homeostatic proliferation…2015 American Transplant Congress
Th17-Mediated Alloimmune Responses Play a Key Role in Intestinal Allograft Rejection in Humans
The Georgetown Transplant Institute, Washington, DC.
The majority of transplanted intestines still falls victim to allograft enteropathy, the underlying mechanisms of which are poorly understood. The purpose of this study was…2015 American Transplant Congress
Donor Lung Preservation With the Organ Care System® Promotes a Tissue Protective and Anti-Inflammatory Response During Transplantation
ObjectivesWithin INSPIRE trial standard cold storage (SOC) is compared to normothermic, ventilated donor lung preservation (Organ-Care-System®, OCS). As lung preservation may influence immune mediators (IM),…2015 American Transplant Congress
Diabetes Mellitus Predicts Outcome in Obesity After Kidney Transplantation
Obesity has been associated with an increased risk of graft loss and death after kidney transplantation. The role of cellular immunity in obese kidney transplant…2015 American Transplant Congress
DEPTOR Is Expressed in CD4+ T Cells and Modulates Effector Responses and Allograft Rejection
Transplant Research Program, Boston Children's Hospital, Boston, MA.
DEPTOR is an evolutionarily conserved, first-in-kind cell intrinsic factor with potential to regulate the activity of multiple intracellular signaling pathways. However, its biology in T…2015 American Transplant Congress
Clinical Utility of Allospecific CD154+T-Cells in Children With Liver Or Intestine Transplantation (LTx, ITx)
Background: Allospecific CD154+T-cytotoxic memory (CD154+TcM) have completed investigational evaluation as predictors of acute cellular rejection in children with LTx or ITx.Purpose: To evaluate CD154+TcM** as…2015 American Transplant Congress
Molecular and Functional Immune Assays as Non-Invasive Diagnostic Tools to Assess the Risk of Acute Subclinical Rejection After Kidney Transplantation
Subclinical allograft rejection (sc-AR) is still a main cause of allograft loss that can only be assessed through invasive surveillance biopsies. We sought to investigate…
