IL-9 induces leakiness in intestinal epithelial cells via modulating tight and adherens junction proteins: Fluorescence microscopy was carried to evaluate the expression of tight and adherens junctional proteins under in vitro conditions (A) Photomicrographs at 60× magnification were taken for tight junctional proteins (Occludin and ZO-1). (B) Photographs at 60× magnification were taken for adherens junctional proteins (E-cadherin and β-catenin). Red arrow represents occludin expression and green represents ZO-1 protein.
