Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium-independent cell-adhesion activity.

The presented data substantiate the hypothesis that claudin-18 is a central barrier-forming component of tight junctions and show that IL-13 downregulates claudin-18. These data also suggest that the loss of claudin-18 is associated with increased sensitization to aeroantigens and airway responsivenessPMID:27215490
