From: Surfactant Protein D modulates allergen particle uptake and inflammatory response in a human epithelial airway model

Figure 3

Pictures displaying the strong modulation of surfactant protein D (SP-D) on distribution of subpollen particles (SPP) within a human epithelial airway model. Left pictures show an overview of the upper side of the epithelial airway model after incubation with SPP with or without SP-D. Right pictures show internalized and attached SPP after masking of cell borders. A) Epithelial airway model after 8 hours incubation with 10 Million SPPB) Epithelial airway model after 8 hours incubation with 10 Million SPP+ 10 μg/ml SP-D. Green: SPP (Alexa 488); red: F-Actin (Rhodamine phalloidin); blue: CD14. Arrows on the left pictures point to SPP which are attached on the surface of the EC, arrows on the right pictures point to SPP inside cells.
