Isolation and Profiling of miRNAs from Formalin Fixed Paraffin Embedded Endomyocardial Tissues from Human Heart Transplant Recipients
R. Nog,^1,2 C. Gupta,^1,2 J. Fallon,^1,2 J. Panza,^1,2 N. Haque.²
¹Westchester Medical Center, Valhalla, NY; ²New York Medical College, Valhalla, NY.
Allograft rejection is a common complication post heart transplant (HTx) and can be confirmed by endomyocardial biopsy (EBx) only. There is however an increasing need…

Molecular Classifiers Can Outperform the Flawed Histologic “Gold Standard” on Which They Are Trained
J. Reeve, P. Halloran.
University of Alberta, Edmonton, Canada.
The histologic diagnosis of rejection in organ transplants is known to be an imperfect gold standard. Therefore, it might be assumed that molecular classifiers built…

Cardiac Grafts from Insulin Resistant Donors Trigger a Heightened Immune Response via Excessive Induction of Autophagy
S. Cai,¹ J. Miao,² A. Chandraker.¹
¹Transplantation Research Center, Renal Division, Brigham and Women's Hospital, Boston, MA; ²Division of Endocrinology, Boston Children's Hospital, Boston, MA.
Background Heart transplantation remains the treatment of choice for many patients with medically refractory heart failure. The use of organs from patients with insulin resistant…

A Pre-Transplant Blood-Based Lipid Signature for Prediction of Antibody-Mediated Rejection in Kidney Transplant Patients
G. Gupta, S. Bobba, D. Contaifer, P. Kimball, A. King, D. Kumar, M. Levy, J. Stern, D. Wijesinghe.
Virginia Commonwealth University, Richmond.
BACKGROUNDThere is a lack of biomarkers for pre-kidney transplant immune risk stratification to avoid over- or under-immunosuppression. Since the circulating lipidome is integrally involved in…

Immunologic Impact of Tocilizumab Treatment in Kidney Transplant Recipients with Allograft Inflammation
J. Leung, S. Chandran, F. Vincenti, Q. Tang.
UCSF, San Francisco.
Background: Proinflammatory cytokine IL-6 increases effector/memory T-cells, induces Th17 cells and prevents the induction of Tregs. IL-6 expression in kidney biopsies is elevated during acute…
