Tight junctions and tight junction proteins in mammalian epidermis
European Journal of Pharmaceutics and Biopharmaceutics, 2009Tight junctions (TJ) are barrier forming cell-cell junctions that are found in a variety of cell types and tissues but their existence in mammalian epidermis has been shown only in the last years. A variety of TJ proteins were identified in mammalian epidermis, comprising several members of the claudin family, occludin, and JAM-A as well as ZO-1 and ...

We have analyzed previous thin-section and freeze-fracture observations of the tight junction. We propose that the tight-junction strands represent intramembranous, cylindrical, inverted micelles. At the junctional site, the exoplasmic halves of the plasma membranes are fused into a continuous leaflet.

Tight junctions of oligodendrocytes
Cell and Tissue Research, 1977Freeze-fracture replicas of the rat corpus callosum revealed prominent junctional strands in fractured cell membranes of the somata of oligodendrocytes. The junctional strands were characterized by an elaborate system of straight or slightly undulating rows of linear aggregates of particles or ridges in the P face and furrows in the E face.

Tight junctions in skin inflammation
Pflügers Archiv - European Journal of Physiology, 2016Inflammation of the skin is found after various external stimuli, e.g., UV radiation, allergen uptake, microbial challenge, or contact with irritants, as well as due to intrinsic, not always well-defined, stimuli, e.g., in autoimmune responses. Often, it is also triggered by a combination of both.

Tight junctions (=zonulae occludentes, TJs) function as an effective barrier in simple epithelia. Recent developments in the molecular biology of TJs revealed that TJs also exist in the stratum granulosum and contribute to barrier function in epidermis. Furthermore, several TJ-related junctions were identified in epidermis.

Perspectives on tight junction research
Annals of the New York Academy of Sciences, 2012The tight junction connects neighboring epithelial or endothelial cells. As a general function, it seals the paracellular pathway and thus prevents back‐leakage of just transported solutes and water. However, not all tight junctions are merely tight: some tight junction proteins build their own transport pathways by forming channels selective for small

MOLECULAR ARCHITECTURE OF TIGHT JUNCTIONS
Annual Review of Physiology, 1998▪ Abstract The tight junction creates a regulated barrier in the paracellular pathway and, together with the actin-rich adherens junction, forms a functional unit called the apical junction complex. A growing number of tight junction–associated proteins have been identified, but functions are defined for only a few.

Tight Junctions and Gap Junctions
2010Tight junctions have several major functions. They seal the intercellular space in epithelial and endothelial cell layers and prevent free paracellular passage of substances. They determine the polarity of epithelial cells by creating a boundary between the apical domain of the plasma membrane and the basolateral domain and prevent diffusion of lipids ...

Tight Junctions and Tissue Barriers
Antioxidants & Redox Signaling, 2011The integrity and function of many vertebrate organs depend on cellular barriers that are mainly formed by intercellular protein complexes of the plasma membrane. These cell-cell contacts, tight junctions (TJs), exhibit the most apical localization in the lateral membrane; they regulate the permeability of the paracellular space between opposing ...
