Impact of PD1, PDL1 Gene Polymorphisms on Allo-Immune Responses after Kidney Transplantation
Hiroshima University, Hiroshima, Japan
*Purpose: The programmed death (PD)-1/PD-1 ligands (PD-Ls) pathway, a member of the B7/CD28 family, triggers an immune checkpoint resulting in inhibition of T cells. Several…2020 American Transplant Congress
Pretransplant BKV-IgG Serostatus and BKV-Specific ELISPOT Assays for the Prediction of BKV Infection
*Purpose: BK Polyomavirus (BK) can lead to major infectious complications and damage to the graft in kidney transplantation (KT). We investigated whether pretransplant BK serostatus…2020 American Transplant Congress
Neuropilin 2 is a Novel Coinhibitory Molecule That Suppresses Alloimmune Responses Following Transplantation
Boston Children's Hospital, Boston, MA
*Purpose: We have previously reported that signaling via the transmembrane receptor neuropilin 2 (NRP2) regulates PI3K/mTOR/Akt activity in several human cell lines. Furthermore, it is…2020 American Transplant Congress
Th17 Cell Inhibition in a Costimulation Blockade Based Regimen for Vascularized Composite Allotransplantation Using A Non-Human Primate Model
*Purpose: Vascularized composite allotransplantation (VCA) is challenged by the morbidity of non-specific immunosuppression required to prevent rejection. The use of highly specific biologics has not…2020 American Transplant Congress
Modulating ITK Signaling Facilitate Allogeneic Skin Engraftment and Clear LCMV Viruses by Regulating IRF-4, JAK STAT and Eomes Expression
*Purpose:Solid organ transplantation is a life-saving procedure to treat end-stage organ failure. However, transplantation of organs between genetically distinct individuals results in acute graft rejection…2020 American Transplant Congress
Can Cxcr3+Cd62l–Cd4+ T Cells Serve as Early Warning Sentinels for Subclinical Rejections after Vascularized Composite Allotransplantation (vca)?
*Purpose: New microsurgical techniques and powerful immunosuppressive drugs have made it possible for severely injured patients to receive VCA to replace limbs, hands, or faces,…2020 American Transplant Congress
Chronic Kidney Disease Alters the T Cell Response to Murine Cytomegalovirus
*Purpose: We have previously reported that patients with chronic kidney disease (CKD) accumulate memory T cells bearing markers of sustained antigen stimulation and enhanced pro-inflammatory…2020 American Transplant Congress
Regulatory T Cells Engineered with TCR-Signaling-Responsive Il-2 Nanogels Suppress Alloimmunity in Sites of Antigen Encounter
*Purpose:2020 American Transplant Congress
B Cell Depletion with Anti-CD20 mAb Exacerbates Anti-Donor CD4+ T Cell Responses in Highly Sensitized Transplant Model
Gastroenterological and Transplant Surgery, Hiroshima University, Hiroshima, Japan
*Purpose: Preformed donor-specific anti-human leukocyte antigen antibodies (DSAs) have been associated with detrimental effects in transplant recipients. To eliminate preformed DSAs, we desensitized DSA-positive recipients…2020 American Transplant Congress
CD11b is a Novel Alternate Receptor for CD154 During Alloimmunity
*Purpose: For decades, blockade of CD40-CD154 has been shown to be a highly effective means of inhibiting alloreactive T cell responses and inducing long-term graft…
