tight junction

Tight junctions exist at the meeting point between two cells.

These cells maintain contact with each other through tight junctions.

There have been approximately 40 proteins identified to be involved in tight junctions.

Tight junctions are made up of many different proteins.

Tight junction protein 1 has been shown to interact with:

A tight junction is formed between the parasite and erythrocyte.

Thus, tight junctions join together the cytoskeletons of adjacent cells.

The cells in the epithelium are connected via tight junctions.

These two types of cells are knitted together by proteins to form what is called 'tight junctions'.

Glucocorticoids play a complex regulating role in the maintenance of tight junctions.

Tight junctions are very important in embryo development.

Electron microscope images show that these cells maintain contacts through tight junctions.

However, this is only applicable for small molecules, as larger ones will not be able to fit through the pores in the tight junctions.

A seal is created by tight junctions of the epithelial cells which line the blastocoel.

They are located just below tight junctions.

Tight epithelia have tight junctions that prevent most movement between cells.

These cells are sealed via tight junctions that prevent flow of Endolymph between them.

This causes water to leave the endothelial cells, which then shrink, opening the tight junctions temporarily.

Together with the Claudin group of proteins, it is the main component of the tight junctions.

The tight junctions on adjacent cells line up so as to produce a seal between different tissues and body cavities.

Modified tight junctions between ependymal cells control fluid release across the epithelium.

This causes an increased leakiness of the tight junctions and thus movement of molecules into the cells.

These changes result from the inactivation of Rho proteins, which play an important role in regulating tight junctions.

This can only be done through transcytosis due to tight junctions, which prevent movement from one plasma membrane domain to another.

(Tight junctions play this role in maintaining the blood-brain barrier.)
