Ultrastructural Changes in Lung Allografts: Endothelial Changes Correlate with Donor Specific Antibody & Antibody Mediated Rejection
M. Alexander, A. Bentall, P. Abell Aleff, J. Scott, A. Roden.
Mayo Clinic, Rochester, MN.
Introduction: Antibody mediated rejection (AMR) causes lung allograft (LA) injury. Challenges with C4d interpretation & lack of specific histological criteria account for difficulty in diagnosing…
