Radiosensitive Cell Population Prolongs Graft Survival of Vascularized Composite Allografts in Non-Human Primates.
M. Uluer, J. Woodall, W. Hassanein, U. Drhu, B. Bojovic, A. Nam, S. Bartlett, R. Barth.
University of Maryland School of Medicine, Baltimore, MD.
Background: Vascularized composite allografts (VCA) containing vascularized bone marrow (VBM) prolong graft survival. To help elucidate this protective immunomodulatory effect, we irradiated donor facial VCA…

Acute Allograft Glomerulopathy: A Distinct Form of Cellular Rejection.
O. AL-Badri, M. Alexander, F. Cosio, L. Cornell.
Mayo Clinic, Rochester, MN.
Background: Acute allograft glomerulopathy (AAG) is an unusual glomerular lesion of allografts with endocapillary hypercellularity, markedly enlarged endothelial cells occluding the capillary lumen, and absence…

Distinct Effects of Chronic Hyperglycemia on Cellular and Humoral Alloresponses In Vivo.
N. Bishop,¹ K. Beard,² R. Gill.²
¹Immunology and Microbiology, University of Colorado Denver, Aurora, CO; ²Surgery, University of Colorado Denver, Aurora, CO; ³Surgery, University of Colorado Denver, Aurora, CO.
Background: Diabetes constitutes a significant problem in the transplant recipient. Diabetes is associated with impaired immunity to pathogens but its effect on alloimmunity remains ambiguous.…

Higher Pre-Transplant HDL Levels Are Associated with Decreased Acute Rejection Following Kidney Transplant.
J. Hagopian,¹ D. Brennan,² K. Lentine,³ T. Horwedel.¹
¹Barnes Jewish Hospital, St. Louis; ²Washington University, St. Louis; ³Saint Louis University Center for Transplant Research, St. Louis.
Purpose: Dyslipidemia is a common comorbidity in patients on the transplant waitlist and post-transplant, and hyperlipidemia has been associated with more robust immune response, possibly…

Antibody-Mediated Rejection Can Be Assessed by Histology When DSA Is Unknown or Negative.
J. Reeve,¹ P. Halloran.²
¹Laboratory Medicine and Pathology, University of Alberta, Edmonton, AB, Canada; ²Department of Medicine, University of Alberta, Edmonton, AB, Canada.
Diagnosis of antibody-mediated rejection (ABMR) in kidney transplants currently requires the presence of donor-specific antibody (DSA) and histologic lesions above somewhat arbitrary cutoffs. DSA is…

Graft Survival in Sensitized and Non-Sensitized Patients: Role of the Combination of Donor-Specific Antibodies and Acute Rejection.
P. Souza,¹ A. Aguirre,¹ G. Bezerra,² H. Rodrigues,² F. Agena,¹ D. David,¹ F. de Paula,¹ E. David-Neto,¹ M. Castro.¹
¹Renal Transplant Service, Hospital das Clínicas de São Paulo, Sao Paulo, Brazil; ²Immunology Laboratory, Instituto do Coração (InCor), Sao Paulo, Brazil.
Background: Sensitized (S) patients have higher risk for acute rejection (AR), especially ABMR. DSA is a risk fator for ABMR, however, its impact on AR…
