Ex Vivo Lung Perfusion Using the Portable OCS Maintains Endothelial Integrity in the Context of Reduced Severe PGD Rates
PurposeThe INSPIRE trial revealed significant reduction of PGD grade 3, i.e. less ischemia reperfusion injury (IRI) using the Organ Care System (OCS) compared to controls…2018 American Transplant Congress
An Increase in Spot Urine Protein Excretion during the First Year after Kidney Transplantation Associates with Subclinical De-Novo Donor-Specific Antibodies and Microvascular Inflammation at 1-Year Surveillance Biopsies
Introduction. We investigated whether an increase in spot urine protein excretion during the first year after kidney transplantation associates with subclinical de-novo donor-specific antibodies (DSA)…2018 American Transplant Congress
Assessing the Impact of Flow in Hypothermic Machine Perfusion on Human Venous Endothelium Using a Novel Ex Vivo Model
BACKGROUNDHypothermic machine perfusion (HMP) involves dynamic flow of chilled preservation fluid through an allograft's vasculature. This study describes a simple, reproducible, human model that allows…2018 American Transplant Congress
Peripheral but Not Follicular T Helper Cells Are Activated by Allogeneic Human Endothelial Cells under IRI-Like Conditions and Promote Donor Specific Antibody
Background: Perioperative ischemia reperfusion injury (IRI) is a consequence of solid organ allograft transplantation that primes the graft for future rejection.Methods: We developed an in…2017 American Transplant Congress
Preceeding the Rejection: Clinical Results of a Saliva Test After Renal Transplantation.
Introduction There remains a need for biomarker in transplantation for monitoring and early identification of rejection episodes (R). We developed a colorimetric assay to detect…2017 American Transplant Congress
TRPV4 Channels Mediate Pulmonary Edema and Inflammation During Ischemia-Reperfusion Injury.
University of Virginia, Charlottesville, VA
Rationale: Lung ischemia-reperfusion (IR) injury remains a major challenge in post-transplant patients. Transient receptor potential vanilloid 4 (TRPV4) cation channels mediate cellular calcium influx, and…2017 American Transplant Congress
HLA Class II Molecules Partner with TLR4 to Stimulate Endothelial Cell Activation and Proliferation.
Pathology and Laboratory Medicine, University of California Los Angeles, Los Angeles, CA
Background: Transplant recipients developing donor specific HLA antibodies (DSA) are at a higher risk for acute and chronic antibody-mediated rejection (AMR). DSA contribute to the…2016 American Transplant Congress
Markers of Activation of Microvascular Endothelial Cells Predict a Poor Long-Term Graft Outcome in Early Renal Graft Biopsies Displaying Acute Tubular Necrosis.
Acute tubular necrosis (ATN), is a histopathological feature frequently seen in the early post renal transplant biopsies taken from patients with delayed graft function (DGF).…2016 American Transplant Congress
Monocyte Recruitment to HLA Class I Antibody-Activated Endothelial Cells Is Dependent Upon mTOR.
Pathology & Laboratory Medicine, UCLA, Los Angeles, CA.
Aim: Antibody-mediated rejection (AMR) is a major issue affecting solid organ transplants, manifesting with recruitment of monocytes to the endothelium of the allograft. The purpose…2016 American Transplant Congress
Levels of VEGF-C, PLGF and Follistatin at 12 Months Post Transplantation Are Associated with Increased Risk for Long Term Progressive Renal Dysfunction.
*contributed equallyIntroduction Integrity of the microvasculature is critical for long term survival after solid organ transplantation. We hypothesize that biomarkers of endothelial injury and repair…
