Primary normal human bronchial epithelial cells (NHBE) from non-smokers, cultured at the air-liquid interface (ALI), were exposed to cigarette smoke in a Vitrocell VC-10 smoking robot. The results show that roflumilast can rescue smoke-induced mucociliary dysfunction.Therefor the ELIZA Assay and qPCR were used.

The aim of this study was to determine the most efficient catalyst for toluene oxidation. Thereby A549 lung cells were exposed using an air/liquid interface (ALI) system and the results are performed with the LDH cytotoxicity test and XME gene expression measurement.

The suitability of using Vitrocell® system as an innovative, direct and dynamic model of ALI exposure in the development of new catalysts is successfully shown.
