MDSCs Prolong Allogeneic Cardiac Graft Survival by Regulating Interferon Type 1 Signaling
S. Cai¹, P. T. Sage¹, T. J. Borges¹, T. Ichimura¹, S. K. Eskandari¹, J. Y. Choi¹, I. Salkuj¹, B. S. AI Dulaijan¹, H. Allos¹, J. Miao², L. V. Riella¹, A. K. Chandraker¹, J. R. Azzi¹
¹Brigham and Women's Hospital, Harvard Medical School, Boston, MA, ²Boston Children's Hospital, Harvard Medical School, Boston, MA
*Purpose: We previously demonstrated that donor-derived regulatory dendritic cells (DCreg), contrary to recipient derived DCreg, promote antigen-specific allograft protection. As myeloid-derived suppressor cells (MDSC) show…

Alloreactive B Cells in Transplant Tolerant Recipients Cannot Differentiate into Antibody-Secreting Cells but Can Suppress Donor-Specific IgG Production By Naïve B Cells
S. H. Khiew¹, J. Chen¹, D. Jain¹, Q. Wang¹, D. Yin¹, M. Alegre², A. S. Chong¹
¹Department of Surgery, Section of Transplant, University of Chicago, Chicago, IL, ²Department of Medicine, University of Chicago, Chicago, IL

Exosomes Isolated from Human Lung Transplant Recipients Diagnosed with Bronchiolitis obliterans Syndrome are Unique in Their Ability to Induce IL-6 via Rab27A Signaling Pathway
M. Rahman, M. Sharma, S. Angara, M. Smith, R. Bremner, T. Mohanakumar
Norton Thoracic Institute, St. Joseph’s Hospital and Medical Center, Phoenix, AZ
*Purpose: Rab27, a member of the Rab subfamily of GTPases, has the ability to induce exosome secretion. Exosomes are small membrane vesicles (40-150nm) that regulate…

IgG Glycosylation Causes Podocyte Injury in Transplant Glomerulopathy through Calcium Calmodulin Kinase IV
R. Bhargava, K. Maeda, M. Pavlakis, G. Tsokos
Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA
*Purpose: Transplant glomerulopathy(TG) is a major cause of late allograft loss. Increase in urine podocin/creatinine ratio in TG signifies acceleration of podocyte detachment from glomerular…

Kidney Allograft Recipient Absence of Myeloperoxidase Decreases Donor-Specific Antibody Titers and Attenuates Antibody-Mediated Allograft Rejection
S. Miyairi, N. Dvorina, A. Valujuskikh, W. M. Baldwin 3rd, R. L. Fairchild
Immunology, Cleveland Clinic Lerner Institute, Cleveland, OH
*Purpose: The incidence of antibody-mediated kidney graft rejection continues to increase. We previously reported that dysregulated donor-specific antibody (DSA) responses were induced in B6.CCR5-/- mice…
