Knockout animals and natural mutations as experimental and diagnostic tool for studying tight junction functions in vivo.

Abstract excerpt

Two sides of functions of tight junctions; the barrier and the channel in the paracellular pathway are believed to be essential for the development and physiological functions of organs. Recent identification of molecular components of tight junctions has enabled us to analyze their functions by generating knockout mice of the corresponding genes. In addition, positional cloning has identified mutations in the...
