Early Mortality After Liver Transplant is Associated with Pre-Transplant Alterations in Monocyte Phenotype and Gene Expression
*Purpose: Persistence of pre-liver transplant (LT) immune dysfunction (immune frailty) significantly increases post-LT morbidity and mortality. We have identified a pre-LT biomarker panel, the liver…2022 American Transplant Congress
Degree of Pre-Liver Transplant Immune Dysfunction Correlates with Post-Transplant Cancer Recurrence
1Rutgers New Jersey Medical School, Newark, NJ, 2Houston Methodist Hospital, Houston, TX
*Purpose: Despite stringent selection criteria for liver transplant (LT) in patients with liver-limited malignancy, post-transplant cancer recurrence remains problematic. We have previously identified a pre-LT…2022 American Transplant Congress
Alloimmune Recognition Blocks Recipient Macrophage Differentiation into Reparative Subsets
*Purpose: Monocytes differentiate into macrophage subsets that orchestrate tissue repair in response to damage signals and local cytokines. After heart transplant (Tx), graft IL-33 acts…2022 American Transplant Congress
Internal Validation of a Pre-Transplant Biomarker Panel to Predict Post-Transplant Mortality: The Liver Immune Frailty Index
1Rutgers New Jersey Medical School, Newark, NJ, 2Houston Methodist Hospital, Houston, TX
*Purpose: Infection and sepsis are the greatest contributors to early post-liver transplant (LT) mortality. These often result from ongoing immune dysfunction, or “Immune Frailty”. We…2021 American Transplant Congress
Hypothermic Oxygenated Machine Perfusion Protects Against Cholangiocyte and Hepatocyte Injury and Mitigates Inflammation vs Static Cold Storage: Preliminary Results from a Single Center
Transplant Surgery, Rutgers NJMS, Newark, NJ
*Purpose: Hypothermic-oxygenated machine perfusion (HMP-O2) is a promising preservation technique with potential to mitigate ischemia/reperfusion injury and improve graft and patient outcomes. Here we present…2021 American Transplant Congress
The Gut Microbiotainduces Local and Systemic Immune Modulation
*Purpose: We previously demonstrated that gut microbiome alterations, through fecal microbiota transfer (FMT) or single bacteria transfer, had specific immune effects for cardiac allograft outcome.…2021 American Transplant Congress
Human Liver-derived Mesenchymal Stromal Cells (MSC) are Superior Inhibitors of Natural Killer Cells Compared to Bone Marrow or Adipose Tissue-derived MSC
*Purpose: Guided by the liver allografts’ unique tolerogenic microenvironment and the immunoprotective impact on simultaneously transplanted organs, we recently isolated liver mesenchymal stromal cells (L-MSC)…2021 American Transplant Congress
Laminins Differentially Regulate Tolerogenic T Cell Migration and Homing to Lymph Nodes
1Surgery, UMB, Baltimore, MD, 2CVID, UMB, Baltimore, MD, 3Harvard University, Boston, MA
*Purpose: Laminin α5 (Lama5) and α4 (Lama4), which are produced by lymph node (LN) stromal cells, influence CD4 T cell migration and stimulation. We hypothesized…2021 American Transplant Congress
Dysregulation of Immune Cell Glycolysis and Oxidative Phosphorylation Correlates with Development of Pre-liver Transplant Immune Dysfunction and Post-transplant Mortality
*Purpose: Cirrhosis-related immune dysfunction contributes to early morbidity and mortality following liver transplant (LT). We have previously identified a pre-LT biomarker panel, the immune frailty…2020 American Transplant Congress
The Gut Microbiota Stimulates Dendritic Cells for Immune Modulation
University of Maryland, Baltimore, Baltimore, MD
*Purpose: The gut microbiota is a driving force in host immune regulation, and thus a potential target for intervention and drug development. We previously showed…
