Fig. 2From: Campylobacter jejuni enters gut epithelial cells and impairs intestinal barrier function through cleavage of occludin by serine protease HtrATight junction protein distribution in intestinal biopsies from healthy individuals and campylobacteriosis cases. Confocal laser-scanning microscopy of human colon crypts from a non-infected individual (a, b) and an acute C. jejuni infection (c, d). The images show clockwise immunostaining for zonula occludens protein-1 (ZO-1, green), occludin (red), nuclei by use of DAPI staining (blue) and a merged image in which co-localization of the tight junction proteins ZO-1 and occludin appears as yellow. White arrows indicate redistributed occludin signals in the infected biopsiesBack to article page
