Filgrastim Utilization Evaluation in Solid Organ Transplant Recipients
The Ohio State University Wexner Medical Center, Columbus, OH
*Purpose: Neutropenia occurs in up to 40% of kidney and liver transplant (txp) recipients and has been associated with higher mortality rates in liver txp.…2020 American Transplant Congress
Recipient Myeloid Cell Myeloperoxidase is Required for Nk Cell Activation During Antibody-Mediated Allograft Rejection
Immunology, Cleveland Clinic Lerner Research Institute, Cleveland, OH
*Purpose: Dysregulated donor-specific antibody (DSA) responses are induced in B6.CCR5-/- mice transplanted with complete MHC mismatched A/J kidney allografts and are required for rejection of…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
Outcomes in Liver Transplantation with Use of Granulocyte-Colony Stimulating Factor
The Ohio State Wexner Medical Center, Columbus, OH
*Purpose: Questions remain if treatment with a granulocyte-colony stimulating factor (G-CSF) impacts clinical outcomes after liver transplant. The purpose of this study was to compare…2020 American Transplant Congress
IL-33 is a Potent Injury Signal That Programs Graft Macrophage Metabolism Toward That Required for Reparative and Regulatory Functions
*Purpose: Sequestered self-molecules, such as HMGB1 or haptoglobin, are appreciated to stimulate the pro-inflammatory response of infiltrating innate immune cells by targeting TLR4 after their…2020 American Transplant Congress
Sialoadhesin Mediates the Adhesion of Human RBC to Porcine Macrophages from Genetically Engineered Pigs
*Purpose: The sequestration of human RBC is prominent after liver and lung xenotransplantation. Rees et al previously implicated porcine sialoadhesin in adhesion of human RBC…2019 American Transplant Congress
Recipient Myeloid Notch1 Disruption Shifts Neutrophil towards Anti-Inflammatory Phenotype and Protects Liver Grafts from Ischemia-Reperfusion Injury
*Purpose: Liver ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and predisposes to rejection crises in orthotopic liver transplantation (OLT). We…2019 American Transplant Congress
Donor Derived Cell Free DNA Initiates De-Novo Donor Specific Antibody (DSA) Responses
*Purpose: We hypothesize that subclinical inflammation, resulting in molecular injury, may contribute to sensitization of the recipients’ immune system. Antigenic presentation of donor-derived nucleic acids,…2019 American Transplant Congress
Local IL-33 Regulates Heart Transplant Infiltrating Myeloid Cells Metabolism and Differentiation to Protect against Chronic Rejection
*Purpose: Self-molecules containing damage-associated molecular patterns stimulate the pro-inflammatory response of infiltrating innate immune cells after their release during tissue injury. Yet, if local endogenous…2019 American Transplant Congress
Timing and Donor-Specific Antibodies, but Not C4d Deposition, Determine Leukocyte Infiltration in Renal Allograft Biopsies with the Histological Picture of Antibody-Mediated Rejection
*Purpose: Diagnosis of antibody-mediated rejection following kidney transplantation can be challenging, given the limited specificity of individual histological parameters and time-dependent occurrence of histological confounders.…
