Abstract Background We characterized changes in expression of the antioxidant protein Peroxiredoxin V PRXV during airway inflammation. Methods Studies in anesthetized rats and mice PRXV expression determined by Western blot analyses and immunohistochemistry PRXV m-RNA expression determined by Taq-Man RT-PCR. Results Bacterial lung inflammation did not change expression of PRXV in murine epithelia but produced massive influx of leukocytes highly expressing PRXV. Endotoxin and f-MLP induced leukocyte migration in rat trachea but did not change mRNA levels and PRXV protein expression in tracheal epithelial cells. In primary airway cell culture cow alveolar epithelial cells A549 or coculture of A549 with murine macrophages RAW264.7 exposure to live bacteria increased expression of PRXV which required serum. .
