This article shows a method for the identification of chemical respiratory allergens. Two respiratory allergens were applied to a 3D co-culture cell system model at the air/liquid interface, mimicking the in-vivo situation in the lung.
The results are shown in cytotoxicity (Propidium iodide, PI), Oxidative burst (Dihydrorhodamine assay, DHR), Pro- and antiinflammatory cytokines IL-2, IL-8, IL-10, IL-13, CD54, TNF-α, IFN-γ, MCP-1, RANTES (Cytometric Bead Array, CBA) and Staining of dendritic cell maturation marker CD86
