Tight junctions in the intestine. This figure is based on previously published data [115] and shows fluorescent staining of occludin in a tissue section perpendicular to the cell surface of the epithelium (A). The fluorescence intensities of 3 different uniform areas per section were plotted as a function of cell location using the peak fluorescence signal from the tight junction region to align each intensity profile (B). Administration of live L. plantarum to humans significantly increased the fluorescent staining of occludin in the tight junction (P < 0.05 for sections indicated *).
