Ambient particulate matter affects occludin distribution and increases alveolar transepithelial electrical conductance

ABSTRACT Background and objective: Inhaled particulate matter (PM) causes lung inflammation and epithelial dysfunction. However, the direct effect of PM on alveolar epithelial barrier integrity is not well understood. Our aim is to determine whether PM exposure affects the alveolar epithelial cells...
