Cytoskeletal rearrangement induced by keratinocyte growth factor (KGF) treatment of alveolar epithelial cells. A and B: diagram indicating the orientation of actin filaments in cells cultured in control medium forming stress fibers (A) or in the presence of KGF, which are predominantly peri-junctional, cortical actin (B). C and D: attachment of transmembrane tight junction proteins (claudins, occludin) to the actin cytoskeleton via the scaffold protein zonula occludens-1 (ZO-1). Increased peri-junctional bundles of actin fibers provide more ZO-1 attachment sites, which stabilize tight junction strands, thus promoting their barrier function. Not depicted in this diagram are other classes of scaffold and transmembrane proteins, which also crosslink tight junctions to the cytoskeleton.
