Figure 2
Water flux and electrolyte concentration in the lateral intercellular cleft. The water flux through the TJ and thus through the lateral intercellular cleft (upper panel) and the electrolyte concentration c 2 (lower panel) are depicted in dependence on the luminal electrolyte concentration c 1 . The results are shown for LI-cadherin binding, i.e. a narrow intercellular cleft (solid line) and for inactive LI-cadherin, i.e. a wide intercellular cleft (dashed line).
