Abstract The impact of PM2.5 on epithelial cells is a pivotal process leading to many lung pathological changes and pulmonary diseases. In addition to PM2.5 direct interaction with epithelia, macrophages that engulf PM2.5 may also influence the function of epithelial cells. However, among the toxic researches of PM2.5, there is a lack of evaluation of direct or indirect exposure model on human bronchial epithelial cell against PM2.5. In this present research, PM2.5-exposed human bronchial epithelial cell line (BEAS-2B) serves as the direct interaction model, while the contrast is to indirect stimulation model, which takes advantage of transwell co-culture system to carry out that PM2.5 is promptly contacted with macrophages rather than BEAS-2B. By comparing these two modes of interaction, we determined the viability of BEAS-2B and mRNA and/or protein expression profile of transcription factors Nrf2,NF-kB and according inflammatory indicators, with a view to evaluating the effects of different interaction modes of PM2.5 on epithelial cell damage in vitro. We have found that macrophage involvement may protect epithelia from PM2.5 cytotoxic effect, while strengthen the inflammation response.

Abstract This protocol describes the establishment and maintenance of differentiated primary human bronchial epithelial cell (pHBEC) cultures from primary bronchial epithelial cells using Lonza and Gibco media. Note: This is a historical protocol. At the time of publication, this protocol has been superseded by a different version in the McCullough lab; however, it is being published to support the transparency and reproducibility of other studies by which it is referenced.Disclaimer: The information presented here has been reviewed and approved for publication by the US Environmental Protection Agency do not necessarily represent Agency policy.
