Increased Ratio of Circulating Tfh for Tfr Cells in Chronic Renal Allograft Dysfunction: A Pilot Study
West China Hospital OF Sichuan University, Chengdu, China
*Purpose: T follicular helper (Tfh) cells play a central role in contribution of B cell differentiation and antibody production. T follicular regulatory (Tfr) cells inhibit…2019 American Transplant Congress
ICOS+PD-1+ Circulating T Follicular Helper Cells Are a Biomarker of Humoral Alloreactivity and Predict Donor-Specific Antibody Generation Following Transplantation
Emory Transplant Center, Atlanta, GA
*Purpose: Mounting evidence in kidney transplantation suggests that donor-specific antibodies (DSA) significantly contribute to renal allograft loss. However, biomarkers to guide clinical management of DSA…2019 American Transplant Congress
Resistance of T Follicular Helper Cells to Depletion by Anti-Thymocyte Globulin
*Purpose: T follicular helper (Tfh) cells are a subset of CD4+ T cells that specializes in providing help for germinal center (GC) reactions where B…2019 American Transplant Congress
Inhibition of Th1 and Th17 Cell Differentiation and Prolonged Graft Survival through NFAT Pathway Downregulation
*Purpose: Extracts Aglaia (family Meliaceae) plants, specially Rocaglamide are used treatment strategy of autoimmune Inflammatory disease and allergic disease in traditional medicine in many Asia…2019 American Transplant Congress
CD4 T Cell is Essential in an Innate-Immune Driven Ischemia-Reperfusion Injury in Mouse and Human
*Purpose: Although CD4 T cells are critical in the mechanism of allograft rejection, little is known about their role in the innate immune-driven ischemia-reperfusion injury…2019 American Transplant Congress
Impact of Everolimus Therapy on HIV Persistence and Gene Expression in Transplant Patients
1UC San Francisco, San Francisco, CA, 2Case Western Reserve University, Cleveland, OH
*Purpose: mTOR is a key regulatory kinase that controls cell-cycle progression. mTOR inhibitors have been shown to reduce expression of CCR5 and promote viral transcriptional…2019 American Transplant Congress
T Cell-Intrinsic Dysfunction in Donor-Specific Transplantation Tolerance
*Purpose: Donor-specific tolerance offers many advantages over current lifelong non-specific immunosuppression strategies, but the mechanisms by which it may be durably maintained remain to be…2019 American Transplant Congress
Costimulation Blockade Modulates Humoral Responses in Highly Sensitized Transplant Recipients
Surgery, Duke Transplant Center, Durham, NC
*Purpose: Broad human leukocyte antigen sensitization is a significant barrier to successful solid organ transplantation. Sensitized patients have poor access to donor organs, high wait…2019 American Transplant Congress
Xenorejection of Porcine Islets in Humanized Mice is Dominated by a Human Th17 Cytokine Immune Response
*Purpose: We have previously shown that interleukin(IL)-17 producing CD4 T cells (Th17 response) dominate in the early anti-donor immune responses of a pig-to-mouse xenogeneic model…2018 American Transplant Congress
IL-17 is Critical for Airway Epithelial Injury after Transplantation
Background: Obliterative bronchiolitis is the major obstacle limiting long-term allograft survival of lung transplantation. Airway epithelium is the primary target in obliterative airway diseases. Th17…
