Allograft TLR9 is Required for Endogenous Donor-Reactive Memory CD8 T Cell Activation in High-Risk Cardiac Allografts to Mediate CTLA-4Ig Resistant Graft Rejection
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: Prolonged allograft cold ischemic storage (CIS) and subsequent increased ischemia-reperfusion injury (IRI) following solid organ transplant act through innate immune pathways that promote early…2022 American Transplant Congress
PSGL-1-mTOR-TIM3 Signaling in a Murine Model of Hindlimb Transplantation
*Purpose: Peri-transplant tissue damage driven by innate-adaptive immune cascades resulting from ischemia-reperfusion injury (IRI) is a major concern in vascularized composite allotransplantation (VCA). Here, we…2022 American Transplant Congress
Toll-Like Receptor-4 Inhibitor, Resatorvid, Attenuates Allogenic T Cell Activation Against Human Pancreatic Islets by Decreasing CD69 Expression
1Baylor University, Waco, TX, 2Baylor University Medical Ctr, Dallas, TX
*Purpose: Allogenic and autoimmune response against islets remain major obstacles to improve long term function of islet transplants. Inhibition of toll-like receptor 4 (TLR4) using…2022 American Transplant Congress
A Low Immuknow Level but Behold….pAMR1(H+) Rejection
Tampa General Hospital, Tampa, FL
*Purpose: PURPOSE: The purpose of this study is to evaluate the mechanism of pAMR1(H+) rejection in heart transplant recipients with low ImmuKnow levels (ATP2022 American Transplant Congress
Antibody Response and Cellular Phenotyping in Kidney Transplant Recipients Following Sars-CoV-2 Vaccination
*Purpose: Correlates of protection for SARS-CoV-2 vaccines are not well-established in kidney transplant recipients(KTRs). Studies have highlighted the importance of neutralizing antibodies(Abs), however data suggests…2022 American Transplant Congress
Assessment of Humoral and Cellular Immune Responses to Sars Cov-2 Vaccination in Immunocompromised Renal Allograft Recipients
Cedars-Sinai Medical Center, Los Angeles, CA
*Purpose: SARS CoV-2 vaccination elicits both robust humoral and T-cell immune responses in healthy individuals. However, a comprehensive assessment of immune responses to SARS-CoV-2 vaccination…2022 American Transplant Congress
Novel Immune Checkpoint Molecule TIGIT Mediates Experimental Kidney Ischemia Reperfusion Injury
Medicine, Johns Hopkins University, Baltimore, MD
*Purpose: T cells play both pathogenic and reparative roles in kidney ischemia reperfusion injury (IRI) but the molecular mechanisms regulating kidney T cell functions are…2022 American Transplant Congress
Neuropilin-2 is a Novel Checkpoint Inhibitor That is Required for Long-Term Allograft Survival
Boston Children's Hospital, Boston, MA
*Purpose: We have previously reported that Neuropilin (NRP) 2-associated signaling events modulate PI3K/mTOR/Akt activity in several human cell lines. While intrinsic NRP1 activity has been…2022 American Transplant Congress
T Cell Overexpression of PD-1 Increases Treg Suppressive Function via an ICOS-Dependent Mechanism
*Purpose: The PD-1: PD-L1 signaling has inhibitory properties and is a potential therapeutic target in transplantation. We have previously demonstrated that overexpression of PD-1 on…2022 American Transplant Congress
Optimal Development and Effector Function of Antibody-Suppressor CXCR5+CD8+ T Cells Requires Host IFN-γ and CD4+ T Cells
*Purpose: We reported the discovery of a novel subset of CXCR5+IFNγ+CD8+ T cells that suppresses antibody production (CD8+ TAb-supp cells). Alloprimed CD8+ TAb-supp cells significantly…
