Pyk2-dependent phosphorylation of LSR enhances localization of LSR and tricellulin at tricellular tight junctions.

Tight junctions (TJs) are cellular junctions within the mammalian epithelial cell sheet that function as a physical barrier to molecular transport within the intercellular space. Dysregulation of TJs ...

The tricellular vertex-specific adhesion molecule Sidekick facilitates polarised cell intercalation during Drosophila axis extension.

In epithelia, tricellular vertices are emerging as important sites for the regulation of epithelial integrity and function. Compared to bicellular contacts, however, much less is known. In particular,...

Cell junction proteins: Crossing the glomerular filtration barrier in diabetic nephropathy.

Diabetic nephropathy as a deleterious complication of diabetes mellitus and an important cause of end-stage renal failure is characterized by changes in the molecular and cellular levels. Cell-cell co...

Cell Biology: Tight Junctions as Biomolecular Condensates.

Two recent studies report that ZO proteins, the main scaffolding proteins of tight junctions, undergo liquid phase separation. This new concept provides understanding at the mechanistic level of how t...

Molecular organization and function of vertebrate septate-like junctions.

Septate-like junctions display characteristic ladder-like ultrastructure reminiscent of the invertebrate epithelial septate junctions and are present at the paranodes of myelinated axons. The paranoda...

Gap Junction Potentiation of Endothelial Function With Rotigaptide

Hypothesis - Rotigaptide will improve endothelial function in the context of endothelial dysfunction. The lining of blood vessels (endothelium) can react to hormones in the blood stream c...

Intestinal Permeability in Obesity

In rodents, obesity is associated with changes in tight junctions' structure in small intestine, which impacts intestinal permeability and results in metabolic complications. Few data exis...

Steroids for Early Treatment of Radiation Retinopathy

Radiation retinopathy is a known complication of ocular radiation therapy. To date there is no known effective treatment. In addition to their anti-vascular endothelial growth factor (VEGF...

Register of Autoimmune Bullous Dermatoses

Autoimmune bullous dermatoses are a group of diseases with chronic course. They are provoked by the production of autoantibodies against the dermal-epidermal junction or against the inter-...

Neuromuscular Transmission in Amyotrophic Lateral Sclerosis

Consistent data suggest that neuromuscular transmission is impaired in ALS patients. Neuromuscular junctions dysfunction may appear very early in the disease, as shown by data in animal mo...

Medical and Biotech [MESH] Definitions

Connections between cells which allow passage of small molecules and electric current. Gap junctions were first described anatomically as regions of close apposition between cells with a narrow (1-2 nm) gap between cell membranes. The variety in the properties of gap junctions is reflected in the number of CONNEXINS, the family of proteins which form the junctions.

A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications.

Cell-cell junctions that seal adjacent epithelial cells together, preventing the passage of most dissolved molecules from one side of the epithelial sheet to the other. (Alberts et al., Molecular Biology of the Cell, 2nd ed, p22)

A group of homologous proteins which form the intermembrane channels of GAP JUNCTIONS. The connexins are the products of an identified gene family which has both highly conserved and highly divergent regions. The variety contributes to the wide range of functional properties of gap junctions.

Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.
