Alloimmune Regulation and Long-Term Allograft Survival Induced by Short-Term Administration of Chinese Medicine Cornus Officinalis and Cuscuta Sinensis Lam
Guangdong Provincial Academy of Chinese Medical Sciences, Guangzhou, Guangdong, China.
Achieving long-term allograft survival or tolerance without continuously global immunosuppression is a highly desirable goal. This study is to induce long-term allograft survival without long-term…2015 American Transplant Congress
Comprehensive Study of 3 Nomenclatures to Discriminate CD8 Subsets in Healthy Volunteers and in Kidney Transplant Recipients
Objective. Historical classification to distinguish central memory (CM), naïve, effector memory (EM), and terminally-differentiated effector memory (TEMRA) CD8 T cells is based on CD45RA and…2015 American Transplant Congress
Lymphatic Endothelium Uniquely Enhances T Cell Migration to S1P
University of Maryland, Baltimore, MD.
Introduction: Sphingosine-1-phosphate (S1P) is a signaling sphingolipid that regulates cell egress from lymphoid and non-lymphoid tissues. While S1P has been described as a chemoattractant, its…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
Mechanisms Underlying Treg Dysfunction in DAIH- Role for PD-L1?
Background: we have previously shown that ex vivo Tregs from patients with DAIH demonstrate differentiation plasticity towards TH17. To understand the mechanisms underlying this we…2015 American Transplant Congress
CTLA4Ig Administered During T-Cell Priming Negates de novo Alloantibody Responses and Modulates Recall Antibody Production
Comprehensive Transplant Center, Cedars-Sinai Medical Center, Arcadia, CA.
Background CTLA4Ig (Belatacept) is a novel anti-rejection therapy aimed at costimulatory blockade. Clinical data suggest that post-transplant alloantibody formation is also reduced in patients treated…2015 American Transplant Congress
Characterization of a Nude Mouse Model of Allosensitization Conditioned by Adoptive Transfer of Follicular T Helper Cells
Comprehensive Transplant Center, Cedars-Sinai Medical Center, Los Angeles, CA.
Background Follicular T helper (Tfh) cells play a critical role in follicular B cell activation and maturation during antibody responses to allograft. Here we report…2015 American Transplant Congress
The Onset of Post-Transplant Malignancies Is Related to a Change in Gene Expression Profiles in Peripheral Blood Mononuclear Cells
Malignancies are the third leading cause of death in renal transplant recipients and their incidence is increasing. Although the role of the immune system in…2015 American Transplant Congress
Cross-Linking of MHC Class I Induces Unique Transcriptional Profiles Associated With Regulation of Both T and B Cells That Precedes Induction of Allo- and Auto-Immunity Leading to Obliterative Airway Disease
Surgery, Washington Univ Sch of Med, St. Louis, MO.
Background: Incidences of chronic rejection, bronchiolitis obliterans syndrome (BOS), remain a major challenge to lung transplantation and development of allo- and auto-immunity has been proposed…2015 American Transplant Congress
Characterization of Peripheral Blood T and B Cells of Sensitized Kidney Transplant Recipients With Long Term Stable Graft Function
We examined the phenotype of T and B cells of peripheral blood of sensitized kidney transplant recipients with stable graft function (GFR > 29mL/min) enrolled…
