Consider a rectangular art gallery divided into n rectangular rooms, such that any two rooms sharing a wall in common have a door connecting them. How many guards need to be stationed in the gallery so as to protect all of the rooms in our gallery? Notice that if a guard is stationed at a door, he will be able to guard two rooms. Our main aim in this paper is to show that Èn/2 ̆ guards are alway...

Tightly controlled epithelial and endothelial barriers are a prerequisite for life as these barriers separate multicellular organisms from their environment and serve as first lines of defense. Barriers between neighboring epithelial cells are formed by multiple intercellular junctions including the 'apical junctional complex-AJC' with tight junctions (TJ), adherens junctions (AJ), and desmosom...

On behalf of the Editorial Board, I am pleased to welcome you to the new Landes Bioscience journal, Tissue Barriers. This is the first cross-disciplinary journal dedicated to the architecture, biological roles, regulation and dysfunctions of tissue barriers and intercellular junctions. We are launching our journal in a very exciting time. The tissue barrier research field is rapidly growing and...

In this synopsis of a symposium at EB2007, we start with an overview of noise and impedance analyses that have been applied to various epithelial barriers. Noise analysis yields specific information about ion channels and their regulation in epithelial and endothelial barriers. Impedance analysis can yield information about apical and basolateral membrane conductances and paracellular conductan...
