Fig. 2From: Protective barrier properties of Rhinosectan® spray (containing xyloglucan) on an organotypic 3D airway tissue model (MucilAir): results of an in vitro studyEvaluation by confocal immunofluorescence microscopy of localization of zonula occludens-1 and occludin in MucilAir cells. a Observation after 2 h of pre-treatment and 16 h of exposure to pro-inflammatory compounds. ZO-1 zona occludens-1, OCL occludin. b Evaluation by confocal immunofluorescence microscopy of localization of zonula occludens-1 in MucilAir cells, where the intensity of the staining of the inflammed tissue was increased to better visualize the different localization of the proteins.
