Protein signatures of remodeled airways in transplanted lungs with Bronchiolitis Obliterans Syndrome obtained using laser capture microdissection

Bronchiolitis obliterans syndrome (BOS), a common form of chronic lung allograft dysfunction, is the major limitation to long-term survival after lung transplantation. The histological correlate is progressive, fibrotic occlusion of small airways, obliterative bronchiolitis lesions, ultimately leading to organ failure. The molecular composition of these lesions is unknown. By laser-capture microdissection and optimized sample preparation protocols for mass spectrometry the protein composition of the lesions in explanted lungs from four end-stage BOS patients were analysed.
