Characterizing the Dominant Phenotype in Kidney Transplant Biopsies: Improving the Prediction of Risk by a Global View of Rejection, Injury, and Atrophy-Fibrosis
P. F. Halloran and The INTERCOMEX Investigators¹, J. Reeve²
¹University of Alberta, Edmonton, AB, Canada, ²Alberta Transplant Applied Genomics Centre, Edmonton, AB, Canada
*Purpose: Interpreting kidney transplant biopsies by histology or molecules involves assigning scores for separate pathologic categories: rejection, acute injury (molecules only), and chronic parenchymal loss…

Rejection Of Optic And Sciatic Transplants
M. Yonar¹, M. Uehara¹, V. Kasinath¹, F. Bei², R. Abdi¹
¹Renal, Brigham and Women's Hospital, Boston, MA, ²Neurosurgery, Brigham and Women's Hospital, Boston, MA
*Purpose: Mechanisms of rejection of peripheral nerve and optic nerve remains largely unknown. The inability to prevent rejection of the optic nerve has thwarted the…

Broadly Profiling the Activation Status of Circulating Immune Cells in Chronic Active Antibody Mediated Rejetion Reveals Increased CD38 and CD16 Expression on Monocytes and NK Cells
K. Sablik, N. Litjens, M. Klepper, M. Betjes
Erasmus MC, Rotterdam, Netherlands
*Purpose: Chronic-active antibody mediated rejection (c-aABMR) contributes significantly to late renal allograft failure. Non-invasive biomarkers of c-aABMR are currently not available but could be valuable…
