520 a Background: Exposure to seasonal or indoor allergens may cause sensitisation and development of allergic airway diseases. We have previously demonstrated that the non-proteolytic major house dust mite (HDM) allergen Der p 2 stimulates pro-inflammatory responses in bronchial epithelial cells. We aimed to determine if other clinically relevant non-proteolytic aeroallergens originating from HDMs, storage mites, cat, dog, birch and timothy also activate respiratory epithelial cells. Methods: Cultures of human bronchial epithelial cell line BEAS-2B, normal human bronchial epithelial cells and alveolar epithelial cell line A549 were exposed to recombinant (r)Der p 2, natural (n)Der f 2, rEur m 2, rLep d 2, rFel d 1, nFel d 1, rCan f 2, rBet v 1 or rPhl p 5a. A panel of secreted mediators and expression of cell adhesion receptors involved in recruitment, survival and adhesion of inflammatory cells in asthmatic airways was assessed. Results: The mite allergens rDer p 2, nDer f 2, rEur m 2 and rLep d 2 as well as the cat and dog allergens rFel d 1, nFel d 1 and rCan f 2 induced granulocyte colony-stimulating factor, granulocyte-macrophage colony-stimulating factor, interleukin (IL)-6, IL-8, monocyte-chemotactic protein-1 and macrophage inflammatory protein-3α secretion from bronchial epithelial cells as well as surface expression of intracellular adhesion molecule-1. The pollen allergens rBet v 1 and rPhl p 5a from birch and timothy did not activate the cells. None of the studied allergens affected the alveolar epithelial cells. Conclusion: These results show that both mite and structurally unrelated cat and dog allergens can activate respiratory epithelial cells by adjuvant-like protease-independent mechanisms.
