Endothelial Junctions. Wolburg and Lippoldt 2002. Endothelial cells are linked one to another by adhesive proteins that are organized in junctional structures. For a long time the mechanisms that underly the formation of tight junctions and the development of apico-basal membrane polarity in epithelial cells have been poorly understood. For instance in the brain where a strict control of permeability between blood and the nervous system is required junctions are well developed and rich in TJ 274 352.
