The Paracellular Channel: Biology, Physiology and Disease serves as the first volume to offer a cohesive and unifying picture of the critical functions of paracellular channels (tight junctions) in different tissues. This new class of ion channel utilizes a completely different mechanism to create ion passage pathways across the cell junction. This volume outlines common principles that govern the organization and regulation of these diverse cellular structures, describes the methodology of study, and highlights the pathophysiologic consequence of abnormal structure and functions of the paracellular channels in human diseases. Coverage includes biochemical, biophysical, structural, physiologic analyses of the paracellular channel, and new technologies for recording and characterization.--

ight junctions (TJs) are cell-ceil adhesion belts that encircle epithelial and endothelial cells at the limit between the apical and the lateral T-membrane. These junctions are crucial for the establishment of separate compartments in multicellular organisms and for the exchange of substances between the internal milieu and the external environment. The perception of TJs has changed over the years. From being regarded as static paracellular seals, they have come to be perceived as dynamic structures that adjust their morphology and function in response to physiological, pharmacological and pathological challenges. The roles that TJs play in epithelial and endothelial cells has also widened, and nowadays this structure is regarded not only as a fence that limits within the membrane, the movement of proteins and lipids between the apical and basolateral membranes, or as a gate that regulates in a size and charge selective manner the transit of ion and molecules through the paracellular pathway, but also as a structure integrated by molecules that participate in the control of cell proliferation. These observations highlight the importance of understanding TJ physiology in order to develop effective strategies for the treatment of pathological conditions such as cancer and autoimmune diseases. This broader perception of TJs is reflected in all the chapters of the book and has been attained thanks to the identification in recent years of a wide array of proteins that constitute TJs in epithelial and endothelial cells as well as in central nervous system myelin.

There has been a dramatic increase in knowledge of tight junctions in the past decade. The molecular structure of tight junctions, cellular functions and the pathophysiological roles of tight junctions are becoming clear. Of the most important functions, the role of the cellular structure in cancer spread and drug delivery are increasingly realised. It is now clear that there are fundamental changes to tight junctions during the process of cancer development. Tight junctions are also critical to the metastatic process of cancer cells. The cellular structure is also crucial in drug therapies, namely, the permeability and bioavailability of the drugs, penetration of barriers such as the blood brain barrier. This current volume aims to summarise the current knowledge of tight junctions, their role in cancer and cancer metastasis and is of interest to scientists and clinicians.
