Abstract

Epithelial cells which line mucosal surfaces (e.g. lung, intestine) critically function as a semi-permeable barrier to the outside world. Mucosal organs are highly vascular with extensive metabolic demands, and for this reason, are particularly susceptible to diminished blood flow and resultant tissue hypoxia. Recent work from a number of groups have defined the critical molecular and cellular determinants of barrier function in hypoxic/ischemic tissues. Here, we will briefly highlight some of these studies from both a basic and clinical viewpoint and provide a perspective on future work related to tigh tjunction function in mucosal hypoxia.
