Fig. 1From: Diesel exhaust particle exposure reduces expression of the epithelial tight junction protein Tricellulin16HBE14o- Monolayers Exhibit Proper Localization of the Tight Junction Proteins Occludin and Tricellulin. Immunofluorescence staining of methanol fixed 16HBE14o- cells with anti-Occludin (red) and anti-Tricellulin (green). Tricellulin is predominantly visible at points of tricellular contact while Occludin is distributed along bicellular junctions. Scale bar 30 μmBack to article page
