    Some claudin proteins, e.g., claudin-2, form actively-gated paracellular channels that define the pore pathway [52,53,56] In contrast to the leak pathway, the high capacity pore pathway channels are exquisitely size- and charge-selective, with a cutoff of ~8 Å diameter [57,58]. This limits the pore pathway to small ions and water and is too T. Sawada, T. Ogawa, M. Tomita, M. Hayashi and S. Awazu.

    We seek to determine whether ZIKV can open the paracellular pathway of STB cells. This route is regulated by tight junctions (TJs) which are present in the uppermost portion of the lateral membranes of STB cells. We analyzed the paracellular permeability and expression of E-cadherin, occludin, JAMs –B and –C, claudins -1, -3, -4, -5 and -7 The residual transepithelial conductance (G{sub T}) and radioisotopic tracer flux under these conditions probably occur via the paracellular pathway. The G{sub T} measured in nontransporting CCD bathed in NaCl solutions was mS/cm{sup 2}. more» When {sup 22}Na or {sup 36}Cl was replaced by a less mobile ion, the G{sub T} decreased by

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 :// Sabyasachi Maiti, in Multifunctional Systems for Combined Delivery, Biosensing and Diagnostics, Paracellular Pathway.

Paracellular transport is a passive transport process that results in the transport of substances across an epithelium by passing through the intercellular spaces in between epithelial cells. There is a large body of evidences suggesting that tight junctions play a /paracellular-transport.

The paracellular pathway is an aqueous, extracellular route across endothelia and epithelia that is followed by substances according to their size and charge. Although under certain circumstances it may be Paracellular pathway book by objects as large as leukocytes, it is generally used by water and small :// The paracellular pathway involves the transfer of peptides and proteins through the space present between the adjacent cells.

This space has radius 8 Å, so only smaller peptides can pass through the space. The only hindrance in the paracellular pathway is the tight intracellular junction of the villus cells [66].

Recent data, both physiological and ultrastructural, strongly indicate that solutes — at least up to the size of small proteins — may permeate the microvascular endothelium via the paracellular pathway.

Paracellular permeability across epithelial and endothelial cells is in large part regulated by an apical intercellular junction also referred to as the tight junction (TJ). The diffusional permeability (P d) of the paracellular pathway to water is μm s −1 and that of the transcellular path is μm s −1.

From the P d data we calculated the filtration permeabilities (P f) for the paracellular and transcellular pathways as and μm s −1, :// Paracellular permeability across epithelial and endothelial cells is in large part regulated by an apical intercellular junction also referred to as the tight junction (TJ).
