Tight junctions' protein expressions. Western blots showing occludin (a), JAM-A (b), claudin-1 (c), claudin-4 (d), claudin-15 (e) protein bands corresponding to their gene expression in H413 clone-1 epithelial cells in response to P. gingivalis, P. gingivalis LPS, and ATP plus P. gingivalis or P. gingivalis LPS. ATP, adenosine triphosphate; JAM, junctional adhesion molecule; LPS, lipopolysaccharide.
